Експериментальне визначення бокового тиску в процесі пресування бетонних сумішей

Abstract

Methodology and results of experimental researches of influence of duration of preliminary vibration, and composition of concrete mixture on distribution of lateral pressure that arises in the process of pressing of concrete standard are considered in the paper. The effect of plasticizing additives on the nature of the distribution of lateral pressure on height has been researched. It is shown that the greatest resistance to pressing has vibrocompressed mixtures with lower water-cement ratio. Concrete specimen lateral pressure height fading increases with increasing compressing pressure.
