✦ Synopsis

This paper presents the results of studies on the effect of micropore structure on the shrinkage of autoclaved cellular concrete with sand aggregate. It has been found that the shrinkage of cellular concrete is the function of vol 1 me and specific surface of micropores of radii 75 < r < 625 . On the base of mathematical analysis the requirements concerning the micropore structure of cellular concrete have been proposed to ensure the proper shrinkage characteristic of this material.

It was proved that autogenous shrinkage of high-strength concrete could be almost the same as drying shrinkage. For cement paste with low water-cement ratio, shrinkage was observed even in water. Existing composite low evaluated well the restraining effect of aggregate on autogenous shrinkage. Moist
