The Influence of Compression Applied during Production to the Compression Strength of Dry Concrete: An Experimental Study

Abstract

Dry concrete is a cementitious material, consisting of aggregates imbedded in a cement matrix. The water cement factor is customary kept low, the compression stress is given to reduce the air voids in the mixture, to enable the entrapped water to optimize the hydration process, and to create more dense material so it will provide a better performance. This study uses 2 types of mix designs and 9 types of compressive stress. The experimental test showed that the greater compressive stress given during the production process increase the compressive strength of the dry concrete until it reaches the optimum point.
