Above values were calculated based on the allowable compressive stress in low density concrete load-bearing walls as stipulated in ACI 523.2R-96 (Guide for Precast Cellular Concrete Floor, Roof and Wall Units), Section 4.3.3 ‘Range of Products’ of the LCC-Siporex Technical Guide. Non load-bearing partitions or curtain walls should be limited to a height/thickness (h/t) ratio of not greater than 48.

Horizontal Wall Panels (WH)

Horizontal Wall Panels (WH)

Similar to WV, they are also reinforced units with either single or double mat reinforcements, but are used in horizontal positions. Applications include: low parapet, boundary walls, wall claddings to steel or concrete framed structures and for filling of space between lintels and ceiling. Tongue and groove joints are usually provided for multi-layered WH construction for ease of on-site assembly.

Fluted Wall Panels (WF)

Fluted Wall Panels (WF)

Wall panels are also available with fluted surface as an added feature. They make very attractive features in building facades used either in small areas such as under window openings or as an all-over treatment. Fluted wall panels are also favorite features for boundary walls. Flutes are available in depths of 25 mm or less.

Partition Wall Panels (WP)

Partition Wall Panels (WP)

These are normally used as non-load bearing internal partitions with thickness ranging from 10 to 15 cm thick depending on the height of wall. The flexibility in the design of partition wall panels means it can be provided with central groove to accept grouting or with standard tongue and groove, increasing their ease of on-site assembly. They are simply fixed using steel angles or by grouting where possible inside framed structures or concrete-shell buildings.

Millings for Wall Panels

Wall panels are milled along their edges to suit various construction conditions and appearance using standard profiles. They may be chamfered or fluted on one or both faces. Following are various shapes of wall panel millings:

Central Groove
Applicable for WV, groove to be filled with cement-sand grout (1:3), providing rigid connection between panels as well as connection to the foundation through steel anchorage and next upper floor through steel dowel bars and ring beams.

Tongue & Groove
Applicable for WV, usually for non-load bearing external cladding or internal partitions where central groove for grouting is not applicable. Also commonly used for boundary walls using WH fixed at the ends to the supporting columns.

Fluted Surface
Can be applied for both WV & WH in combination with Central Groove or Tongue & Groove for architectural purposes. Depth of flute can be 25 mm or less. Standard distance between flutes is 100 mm center to center.

Plain Corners
Used in combination with Central Groove or Tongue & Groove where plain wall surface is required. Fiberglass tape fixed with our special adhesive, Gesol, along the joints will be necessary prior to application of wall finishes.

Chamfered Corners (one or both faces)
Also used in combination with Central Groove or Tongue & Groove where joints between panels are required to be visible, forming V-grooved joints. This is appropriate for Siporex wall panels used as claddings to a framed structure.

Fiberglass tape will not be necessary where chamfered corners or V-grooved joints are provided.

Note: All dimensions indicated above are in “mm”.

LINTELS

Panel Type Lintels (LW)

Panel Type Lintels (LW)

Lintels are used as load-bearing members over window and door openings for external or internal walls, eliminating the need for shuttering and in-situ concrete. They are bedded with special Siporex glue onto wall panels adjacent to the opening of reduced height. The maximum obtainable lengths (free spans) in meters for lintels of various design loads and thicknesses are shown in table below. LW’s usually have standard height of 60 cm.

Maximum Clear Span of Panel Type Lintels with Various Design Loads (Height = 60 cm)
Design Load	Thickness of Panel Type Lintel (mm)
Design Load	100	150	200	250
500 kg/m	250 cm	450 cm	540 cm	540 cm
1000 kg/m	200 cm	325 cm	400 cm	450 cm
1500 kg/m	100 cm	275 cm	325 cm	375 cm

Arch Type Lintels (LA)

Arch Type Lintels (LA)

Arch type lintels are also load-bearing members but with added architectural features that can be designed with various shape and sizes of arches applicable for openings at external facades or internal walls. Reinforcement mats are specially arranged to facilitate fabrication and avoid exposure after cutting the required shape. Arches can be designed with single panel where height of arch does not exceed 30 cm or multi layers of panels for high arches.

Box Type Lintels (LB)

Box Type Lintels (LB)

Box type lintels are designed with special steel reinforcement arrangement to be used where lintel depth is limited. They are suitable for block wall construction, produced with depth equal to the height of Siporex blocks for ease of construction. This eliminates shuttering and cast-in-situ works as well as avoids thermal bridges caused by the use of traditional concrete lintel. The maximum obtainable lengths (free spans) in meters for Box type lintels of various design loads and thicknesses are shown in table below.

The minimum permissible end bearings for all types of lintels are as follows: for L ≤ 2400 mm 200 mm each end for L > 2400 mm 300 mm each end Due to the special reinforcement arrangement, lintels must never be cut.

Maximum Clear Span of Box Type Lintels with Various Design Loads (Height = 25 cm)
Design Load	Thickness of Box Type Lintel (mm)
Design Load	100	150	200	250
500 kg/m	200 cm	350 cm	360 cm	360 cm
1000 kg/m	150 cm	250 cm	260 cm	265 cm
1500 kg/m	75 cm	200 cm	210 cm	210 cm

Other heights and spans of lintels can be designed by our technical department depending on their particular condition and considering the clear span of openings as well as design loads. Since Siporex lintels are constructed with the same materials as the wall panels or Siporex masonry blocks, the surfaces are easily finished and the possibility of cracks due to different thermal expansion is eliminated.

FLOOR & ROOF SLABS

Siporex slabs are also produced in various thickness and spans depending on the required load-bearing capacities. The table shown below gives a guide to the permissible spans of slabs with different design loads of various slab thicknesses. FS & RS can be used in all types of buildings, e.g. housings, industrial, commercial & educational buildings.

Roof Slabs (RS)

Floor Slabs (FS)

Product and Application

Siporex floor/roof slabs are reinforced aerated concrete products which are produced in accordance with international standards.

Siporex slabs attain their design strengths during the high-pressure steam curing process in the autoclaves. Thus, after delivery, slabs can be erected immediately within a very short period and ready for occupancy use.

Installation can be done with minimal number of erection crew, light equipments and will not require highly skilled workers. Shuttering works are eliminated, and finishing works can commence directly, saving time and overall costs.

Siporex slabs can be used both in flat roof areas or sloped roof. They can also be installed with cantilevered ends, produced with special reinforcements.

The excellent thermal insulation of Siporex slabs ensures pleasantly healthy and balanced internal temperature. The units are milled along their edges to provide tongue & groove and grouting notch on top. The bottom longitudinal edges are preferred to have corner chamfers giving an attractive V-shaped joints pattern on the ceiling.

SIPOREX BLOCKS

Product Application & Characteristic Data

Siporex solid blocks are used as load-bearing and non load-bearing walls and as thermally insulating roof tiles in addition to being used as Hordi blocks or infills for ribbed slabs. They are produced with very precise dimensions with slim tolerance of ±3mm for thickness and width, therefore they are able to be laid by thin-bed mortar (Siporex glue) with a maximum of 3mm thick mortar joint. This results to a high quality wall structure with uniform thermal insulation and fast installation.

Masonry Blocks Dimensions

For the past decades, LCC Siporex had been supplying Autoclaved Aerated Concrete (AAC) blocks with a standard face size of 25 cm high x 60 cm long only in various thicknesses. However, due to the increasing demand and growing popularity of the use of AAC blocks, LCC Siporex have started the production of new dimensions of blocks in line with the continued expansion of additional manufacturing plant to sustain the market requirements. Siporex blocks are now produced at the following standard sizes:

Standard face size: 25 cm high x 60 cm long: | Thickness: 10, 15, 20, 25 and 30 cm

Standard face size: 20 cm high x 60 cm long: | Thickness: 10, 15, 20, 30 and 40 cm

Hordi Blocks

Hordi blocks or infill blocks for ribbed slabs can be produced in various dimensions to form lightweight infill between in-situ reinforced concrete ribs designed to span in one or both directions. Due to their excellent bondage to in-situ concrete, Siporex Hordi blocks are easily arranged to form permanent part of the slab, providing excellent thermal insulation as well as fire resistance material. Hordi blocks are produced with density of 450 kg/m3 according to the following dimensions:

Length : 60 cm Width : 37/38 cm or 40 cm Thickness : 20, 25, 30, 35 cm

Other sizes may be produced upon request only.

Hordi blocks are not available in stock and are manufactured against order only.

Thermal Insulating Tiles

Roof insulation of existing conventional roof can still be improved with the use of Siporex thermal insulating tiles available at the following dimensions:

60 x 60 x 7.5 cm 60 x 25 x 7.5 cm 60 x 25 x 5 cm

Other dimensions can be produced upon request.

Packing Data for Siporex Blocks

Siporex blocks are delivered ready for use and packed in easily transportable wooden pallets. The pallets should be unloaded at the site by construction-site cranes, forklifts or other suitable hoisting equipments. For ease in unloading of materials, it is suggested to order Siporex blocks in whole bundle or pallet volume to avoid handling loose quantities. Following table is an easy reference in making order of some standard sizes of Siporex blocks in bundles or pallets.

Block Laying

The first course should be laid on cement-mortar bed of thickness about 1 to 3 cm depending on the evenness of the base and should maintain a correct level for fast installation progress in the following courses. It is recommended to spray the mortar face of the block before installation to keep damp at erection time especially during the hot seasons. After installation, spray with water twice a day for 3 consecutive days for curing of the mortar. Three types of Mortars can be applied on the succeeding courses:

Glue for Siporex (BONDCHEM – for thin joints):

Pre-mixed mortar – only water is to be added. Thickness of glue should not exceed 3 mm in horizontal and vertical joints in order to achieve the ideal consumption rate as follows:

7 kg/m2 for Siporex blocks 25 cm thick 6 kg/m2 for Siporex blocks 20 cm thick 5 kg/m2 for Siporex blocks 15 cm thick

Ordinary Mortar with Gesol

1:6 Cement : Sand (by volume) respectively in addition to water (with 10% of Gesol). The erection can be carried out normally as for conventional blocks. (Gesol is a liquid material used as bonding agent and retardant for the mortar especially during hot weather. Gesol is available at Siporex factory in 3 kg and 25 kg plastic containers).

Ordinary Mortar with Lime:

1:1:10 Cement : Lime : Sand (by volume)

Plastering of Siporex Block Wall

Before plastering, dirt and loose particles should be removed from walls. Spray walls with water and follow one of the two methods mentioned below:

Traditional Plastering: Similar to plastering of conventional block walls with the following mix:

Splattering (3mm): Use 1 cement : 3 sand mixed with solution of water and Gesol (20% of the volume). Spray with water twice a day. Ordinary Plastering Mortar: (1 – 1.5 cm thick, apply 24 hours after the splattering) Use 1 cement : 6 sand mixed with solution of water and Gesol (10% of volume).

Plastering with Pre-mixed Mortar Water is added to the pre-mixed plaster supplied in bags of 25 and 50 kgs. Surfaces should be thoroughly cleaned and wetted without any splattering. Apply plaster directly with a thickness ranging between 0.5 to 1 cm In both above methods, walls should be watered twice a day after plastering for three consecutive days.

Cladding with Marble or Artificial Stone

Marble or artificial stones are fixed using hooks and screws. It is necessary to use screws with plastic plugs like Fisher and Hilti anchors in addition to several other types specially made for use in cellular concrete. Refer to “Typical Connection Details” at Section 7 of the LCC-Siporex Technical Guide

Bolts and Fixings

Various type of bolts and fixings applicable for both Siporex blocks walls and reinforced panels are discussed in Section 10 of the LCC-Siporex Technical Guide. These types of fixings are used in installation of doors and windows, as well as wall accessories with weights not exceeding the allowable loads of the type of fixing used. Through-bolts should be used in case of heavy fixtures such as water tanks and hanging lavatories (please Refer to “Fixings to Siporex” at Section 10 of the LCC-Siporex Technical Guide).
