Lightweight Concrete Blocks | Lightweight Precast Concrete
Lightweight precast concrete blocks are normally made by expanded clay, slate or shale, it can help to reduce weight as compared to ordinary concrete aggregates where it might comprise of granite, quartz, crushed limestone and others; the key point here is the porousity of the aggregate particles.
A well-known product is the AAC, also called as Autoclaved Aerated Concrete in Malaysia. The below we will introduce a little bit of AAC and why it is so well accepted and having a high demand in the construction industry Malaysia. Consult us as AAC blocks supplier Malaysia, to give you best advise on the specification you might required for your building.
Autoclaved Aerated Concrete
There are many AAC block suppliers in Malaysia and they are doing well and the common issue constructor always face is they need to pre-order and ready stock is always not the case. AAC has many names in the construction industry such as autoclaved concrete, autoclaved cellular concrete (ACC), cellular concrete, autoclaved lightweight concrete (ALC), porous concrete and many more. From wall panel, slab or floor panel, roof as far as lintel and façade (cladding).
AAC blocks supplier Malaysia also claim that AAC can act as an insulator against sound, heat, fire; resistant agent to mold, water beside it can be used as a structural building materials for internal wall, external wall, roof and floor. AAC lightweight block in Malaysia is also very popular because it allows you to build fast and easy to use where inexperienced workers or house owner can Do-It-Yourself (DIY) with proper instruction information given.
Due to the raw materials and process of manufacturing of AAC by all the AAC block manufacturer in Malaysia, it is basically having high insulation against thermal. The steam curing process involve high pressure, and it the physically properties of these AAC are consisting of more than millions tiny air pockets which are not connected to each other. The materials used to make AAC are sand, cement, aerating agent and lime, mixtures will be allocated by AAC blocks supplier in Malaysia to all the mould sizes and subsequently to form the lightweight AAC bricks, AAC blocks, AAC panels and AAC lintels as a result of autoclave’s curing.
Lightweight also mean you need lesser structural supports to be built, and mortar for joints of each blocks also lesser due to its reduced joints’ number (bigger of each block’s size than conventional brick). It applies to the plastering and rendering too where cost savings can be achieved by having a dimensionally stable and accurate blocks, with also thinner plastering thickness. Heat insulation product by AAC brick supplier in Malaysia saves you in term of time, efforts and costs to install additional heat insulation materials.
Lightweight Reinforced Concrete (LRC)
Lightweight structural concrete. Lightweight aggregate concretes supplied by lightweight block supplier Malaysia can be used for structural applications, with strengths equivalent to normal weight concrete. The benefits of using lightweight aggregate concrete include: Reduction in dead loads making savings in foundations and reinforcement.
Lightweight aggregate concrete supplier in Malaysia product the lightweight concrete panel by using the by-products of industrial manufacturing plant such as fly ash from boiler furnace of power plant. One of the most popular lightweight concrete materials are foam, sometime also known as polystyrene foam or expanded polystyrene foam (EPS).
They are either a slurry of concrete and foam or made into sandwich panel. Foam sandwich panels are also come into different format either the foam are in between of two outer layers of concrete panels or a concrete layer is surrounded by two outer layers of foam. Consult us, as a leading lightweight concrete panel supplier in Malaysia who can provide you supply and install solution for your project.
Expanded Polystyrene Foam - EPS Concrete Sandwich Panel
This type of polyfoam, polystyrene foam concrete panel is popular also in Malaysia due to its heat and sound insulation, polyfoam supplier in Malaysia will send the polystyrene or expanded polystyrene to the prefab or precast concrete panel manufacturer in Malaysia.
After that, the precast or prefab concrete panel supplier Malaysia will process the foam to make it cut into size or blend into its concrete mixture, depend on the designs by architect.
Blended polyfoam with concrete is easy with special additives to make sure the adhesion of foam and premix concrete, the lightweight concrete foam panel manufacturer in Malaysia will then send to any construction site in Malaysia and pour into formwork that has been setup, or alternatively by the site contractor. Otherwise, the premix supplier will pour into the mould in their own factory to foam a foam concrete panel, either for wall, slab, roof or other infrastructure components, send it after it is cured.
Industrialized Building System IBS for Lightweight Block Malaysia
The subsequent designs which the lightweight concrete block for this type of green building materials (GBI certified) industrialized building system, IBS products are more to prefab and precast concrete panel supplier in Malaysia whereas per mentioned above, the only different is the polystyrene and concrete layers in-and-out. If the design is polyfoam layers outside of the concrete panel (also sometime known as insulated concrete forms, ICF), normally the concrete panel manufacturer in Malaysia will either attach the foam layer before sending to site or just assemble at the construction site with starter bars, precast supplier (Precast Lightweight Reinforced Concrete, LRC supplier) will do the first option and prefabricated polystyrene panel supplier will do the later one (cast-in-situ).
Last but not least for the other design is where layers are in between the concrete panels, the supplier of this polystyrene concrete panel in Malaysia normally will do the sandwich panel assembly at site, Cast-In-Situ Reinforced Concrete will be formed after the lightweight block contractor Malaysia spray (shotcrete) or pour the concrete into the formworks in which the expanded polystyrene that have installed. This type of light weight concrete block supplier Malaysia will of course to do the machining work which is to attach the high tensile BRC wiremesh into the expanded polystyrene to make sure concrete adhesiveness and create the structural integrity between poly foam and the concrete layers.
