Ordinary AAC Blocks (whatsApp Riva

Autoclaved Aerated Concrete or AAC is a lightweight, precast concrete material that comes in two forms: blocks and panels. It was developed in Sweden during the 1920s. AAC offers structural strength, heat and sound insulation, and fire resistance in one material.

Being aerated, AAC contains 50-60% air and has a density of 750 kgs/cbm. Although it weighs only about 40% of conventional CHB, the compressive strength averages 4.25 MPa which is twice the PNS (Philippine National Standard) requirement for Type II non load-bearing CHB.
Unlike other concrete products, AAC may be sawn, drilled, chiseled, nailed or screwed using conventional carpentry or electric power tools. Thin bed mortar is used as adhesive to join the blocks or panels together.
Its main ingredients (cement, lime, silica sand, gypsum, and water) are mixed into a slurry. Aluminum powder is added as an expansion agent. The chemical reaction generates tiny air bubbles and causes the mixture to expand to nearly twice its original volume.
After its initial setting, it transforms into a semi-solid state which is then wire cut into precisely sized blocks or panels and then baked (autoclaved).
Autoclaving uses high-pressure steam at temperatures of up to 190°C to accelerate hydration of the concrete. It can produce in 8 to 14 hours concrete strengths equal to that of concrete moist-cured for 28 days at 70°F.

Raw material

- Siliceous materials: Sand/Fly ash/ Tailings containing silicon/ Ceramic waste

- Calcareous materials: Lime bock + Cement + Gypsum

- Others: Aluminium powder paste

Advantages
♥ Lightweight : density of AAC block is 400-700kg/m3,1/3 of solid clay blocks, 1/5 of common concrete blocks.
♥ Fire proof : main materials of AAC blocks are inorganic. it has features of keeping temperature, resisting fire and
releasing no harmful gas.
♥ Sound insulation noise reduction :with distinctive large quantities of pores inside, AAC blocks have great sound insulation, its sound insulation index of 100mm thick can achieve 40.8db
♥ Good heat preservation,energy saving : with a large number of pores inside, AAC blocks have good heat preservation
♥ Reducing project cost and Convenient construction : surface of AAC blocks are smooth, it needn't plastering , lots of decoration costs will be saved. It can be sawed, cut, drilled freely and bound with other building materials which is favorable for building
♥ Anti-seismic :AAC blocks have light weight, so it have low inertia and good performance on anti-seismic
♥ Environmental protection :slag, flyash, mine waste and other industrial wastes can be used as raw material of ALC panel,which is friendly to environment
