Abstract
In this report, the results of experimental studies on the effect of water-cement ratio. air-bubble content and volume of rightweight aggregate per unit volume of concrete on the compresive strength properties of natural cured cellular concrete, and to improve compresive strength of cellular concrete through variation in mix-proportions and addition of lightweight aggregate are described. The results are as follows. (1) The compresive strength of natural cured cellular concrete is depends on the void-cement ratio. (2) It becomes an effective method to increase the compresive strength and young's modulus of natural cured cellular concrete, that addition of lightweight aggregate. Increase of unit weight of cellular concrete, by addition of light weight aggregate, is a little.
