STRENGTH DEVELOPMENT OF SUPER-PLASTICIZED PLAIN AND FLY ASH CONCRETES . ADMIXTURES FOR CONCRETE: IMPROVEMENT OF PROPERTIES. PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM HELD BY RILEM (THE INTERNATIONAL UNION OF TESTING AND RESEARCH LABORATORIES FOR MATERIALS AND STRUCTURES), BARCELONA, MAY 14-17, 1990
Compressive strength and water penetration of four mixes of structural grade plain concrete with cement content ranging from 250 to 400 kg/m cubic metre and fly ash concrete with fly ash cementitious ratio of 0.32 are reported. These mixes were redesigned by adding a proprietary superplasticiser at a recommended maximum dosage of 1.2 litres per 100 kg of cementitious material, maintaining similar workability. The strength development in three curing regimes was monitored. The results suggest that lower grade mixes of fly ash concrete benefited the most when proper curing was provided. However, the strength development of plain concretes was better than the companion fly ash mixes when limited initial curing was provided. The higher strength development of the superplasticised concrete was the maximum for mixes with high water cementitious ratios. (Author/TRRL)
