Cement Foam Concrete with Low Shrinkage

Abstract

The results of studies of fiber reinforced cement foam concrete with mineral and synthetic fibers are given in the article. Introduction of fibers in the amount of 0.1-2% of the weight of cement in the foam concrete mixture enables increase in the strength of the foam concrete in 28 days by 2.5 -fold, decrease in the thermal conductivity by 30-40% and the shrinkage strain by 42-90%.
