High-Performance Concrete Incorporating Rice Husk Ash as a Supplementary Cementing Material

摘要: This paper presents results on the physical and chemical properties of rice husk ash (RHA), deals with fresh hardened concrete incorporating same ash. The investigated included workability, bleeding, setting time, autogenous temperature rise, those compressive, splitting tensile, flexural strengths, modulus elasticity, drying shrinkage, resistance to chloride ion penetration, freezing thawing cycling, salt-scaling resistance. In addition effects percentage RHA water-cementitious materials ratio investigated, were also compared control Portland cement silica fume concrete.
