This paper presents a study on the geometric pore structure and the distribution of pores in AAC, based on an idealistic mathematical model. The aim is to provide information that is practically relevant for the optimization of AAC products.
Autoclaved aerated concrete is a porous concrete formed by chemical gas generation of aluminum powder. The geometric shape of the hole is a spheri- cal pore or a near-spherical pore, and the pores are closed independently.
The wall thickness of the matrix, i.e. the minimum distance between the edges of two neighbouring pores, as well as the pore size distribution have im- portant effects on the performance of AAC. When matrix performance and wall thickness are fixed, then an increase in the curvature of the pore sur- face, i.e. a decrease in the equivalent diameter of the pore, results in an increase in the relative pore compressive strength. When the equivalent diameter of the pore is fixed, then an increase in the wall thickness of the matrix results in an increase in the matrix compressive strength.
In accordance with its mission “Green Solution, Greener Life”, Keda Suremaker is permanently focusing on environmental protection and energy conservation issues. In order to investigate its practices to this effect, Keda Suremaker decided to analyze its heat consumption fıgures pertaining to AAC products to determine possible methods of heat loss reduction during the production process of AAC and correspondingly lower atmospheric carbon emission as much as possible.
The calculation of the autoclaved heat balance that this article addresses is based on data obtained from a Keda Suremaker AAC block production line with the following features:
Annual block production capacity: 300,000 m³; Mould size: 6 × 1.2 × 0.6 m; 4,32 m³
Autoclave specification Φ 2.68 × 38 m; Final product: B05 grade block;
Good quality product rate: 100 %.
