Changes in length, compressive strength, dynamic modulus of elasticity and pulse velocity of high fly ash content concrete with replacement levels of up to 50 % when completely immersed in the IO % Na2S04 solution were periodically measured for 2 years. It was found from the measurements of mechani

Modern thermal power plants are producing large amounts of fly ash that is generally quite suitable for use as a supplementary cementitious material in concrete. However, for tilis purpose the fly ash utilization in the United States continues to remain low, mainly on account of lack of quality cont
With otherwise similar chemical end mineralogical composition of fly ash, is it its fineness which has the most significant influence on the properties of concrete. Coarser fly ash is, as a rule, suitable only as a substitute of s portion of fine aggregates or as s correction of unsuitable shape and
This research was conducted to evaluate abrasion resistance of high-volume fly ash concrete. A reference plain portland cement concrete was proportioned to obtain 28day strength of 41 MPa. Concrete mixtures were also proportioned to have two levels of cement replacements (50 and 70%) with an ASTM Cl
