What is the density of aerated concrete?
What is the density of aerated concrete?
4.2. 1.1 ‘Homogeneous’ porous concrete ( = 500–800 kg/m3)
| Kind of Concrete | Density (kg/m3) | Compressive Strength (N/mm2) |
|---|---|---|
| Ordinary | 2200–2300 | 20–50 |
| Light-weight∗ | 1400–1900 | 15–30 |
| Aerated | 500–800 | 3–8 |
How much does aerated concrete weigh?
Howev- er, unit-by-unit comparison shows that one standard AAC block weighs 27 pounds while one stan- dard CMU block weighs 34 pounds.
What is the R value of aerated concrete?
AAC offers an R value of about 1.25 for each inch of material thickness. But AAC has a high thermal mass, which slows the transfer of thermal energy and can greatly reduce heating and cooling costs.
Why is aerated concrete autoclaved?
AAC has been produced for more than 70 years, and it offers several advantages over other cement construction materials, one of the most important being its lower environmental impact. Improved thermal efficiency reduces the heating and cooling load in buildings. Porous structure gives superior fire resistance.
How do you find density of AAC block?
Weight of AAC Block is determined by multiplying volume and their density, volume is calculated by multiplying its length, height and their thickness such as weight of 1 aac block = volume × density, we know dry density of aac block = 600 Kg/m3 & wet density = 800 Kg / m3.
What is the density of concrete in kg m3?

What is autoclaved concrete?
Autoclaved aerated concrete (AAC) is a lightweight, precast, foam concrete building material suitable for producing concrete masonry unit like blocks. Composed of quartz sand, calcined gypsum, lime, cement, water and aluminum powder, AAC products are cured under heat and pressure in an autoclave.
What is autoclaved aerated concrete used for?
Autoclaved aerated concrete is factory-made, and the material is molded into blocks or slabs with precise dimensions. These can be used for walls, floors and roofs. Similar to all cement-based materials, AAC elements are strong and fire resistant.
What is high density concrete?
High-density aggregates are used to produce concrete that has higher than normal density, usually for radiation shielding or an application where high-density concrete is needed for counter balancing, ballasting, or stabilizing.
