Abstract

Experimental studies were made by molding the self-consolidating concrete (SCC) with a single layer and comparing strength results with the normal molding procedure. The experiments were conducted to estimate the variation in strength and to provide technique in molding the SCC. The concept was first developed to avoid over-consolidation of concrete and try to simulate the usage of SCC under site conditions. The compressive strength of concrete showed approximately the same results as compared with the compressive strength of concrete that was molded in accordance with the ASTM C31/C31M-06 test method. The degree of concrete control based on standard deviations and coefficient of variations was improved.
