Abstract

The aim of this study is to produce one types of lightweight concrete which is known as ( gas concrete ), four additions of aluminum powder ( 0.1, 0.2, 0.3, 0.4) % by weight of cement were used to produce gas concrete. Two different ways of curing, air and steam curing, were carried out using (5)cm cubes specimens. The test results showed that the density and compressive strength of gas concrete decreases with the increase of the percentage of aluminum powder (Al). The density of gas concrete was between (1177.1-1524.38) kg/m3 and (1246.24-1593.94) kg/m3 for air and steam curing, respectively when the percentage of aluminum powder was between (0.1—0.4) % by weight of concrete. The addition of (Al) also increases the volume of gas concrete. It was between (13.3- 50.8)% and (18.7 – 61.3) % for air and steam curing respectively while (Al) was between (0.1-0.4) %The test results showed that the best percentage of (Al) was 0.2% by weight of cement which gives density (1389.98) kg/m3 and compressive strength (0.26)MPa for air curing and (1431.95) kg/m3nand (0.55)MPa for steam curing.
