Aerated concrete can be classified as autoclaved aerated concrete (AAC) and non-autoclaved aerated concrete (NAAC) based on the process of pore-formation, the type of binder, and the method of curing [24]. The AAC properties such as drying shrinkage compressive strength, water absorption, and density directly vary on the curing process and ...

Aerated concrete is either a cement or lime mortar, classified as light weight concrete, in which air-voids are entrapped in the mortar matrix with the aid of suitable air entraining agent. Aerated concrete is relatively homogeneous when compared to normal concrete, as …

Autoclaved aerated concrete (AAC) is a light porous silicate product, which is made of siliceous materials (sand, fly ash, silica-containing tailings, etc.) and calcareous materials (lime, cement) as the main raw materials, and gas-forming admixtures (aluminium powder) as the main additive agent. Manufactured by mixing, pouring, pre-curing ...

The influence of polycarboxylic-type admixture on the strength of autoclaved aerated concrete (AAC) was investigated. The flexural strength and compressive strength of AAC with polycarboxylic admixture (PA) were tested. The microstructure of AAC reinforced by PA was analyzed using scanning electron microscopic (SEM) methods. The crystal structure analysis of AAC with PA …

Highlights Carbon fibre additives act as nuclei during the autoclave hardening of aerated concrete. Size of carbon fibre additives depends on the way of their mechanical treatment. The higher is amount of small carbon fibre particles the higher is degree of crystallinity. The higher is degree of crystalinity, the better are properties of autoclaved aerated concrete.

Answer: I got an everlasting problem with a aerated autoclaved concrete (also known as "Gasbeton") wall: there's a crack that seems to split the upper half from the bottom half of the wall. I tried several time to fix it, either with the proper aerated autoclaved concrete putty and with stucco b...

Poromix AAC Additive is a new generation of chemical additives developed specifically for autoclaved aerated concrete (AAC) production optimization. Its primary function is a reduction of raw materials and reduction of water required in the AAC mix complemented with stabilizing function, homogenizing function, catalyzing function. 25.

We investigated the effect of joint grinding of Portland cement clinker, silica and carbonate components and mineral additives to specific surface of 280 - 300 m 2 /kg on the properties (strength, average density and thermal conductivity) of non-autoclaved aerated concrete, and the porosity of the hardened cement paste produced from Portland cement clinker with mineral additives.
