Performance of Silica Fume on Preventing Strength Retrogression in Hardened Cement Paste and Mortar at Elevated Temperatures

Effect of Partial Replacement of Cement by Silica Fume on Hardened Concrete

The use of Silica Fume (SF) in short period of time had one of the most dramatic impacts on the industry’s ability to routinely and commercially produce SF modified concrete of flowable in nature but yet remain cohesive, which in turn would develop both high early and high later-age strengths including resistant to aggressive environments. This paper features an experimental study on the nature...

Efficiency of calcined kaolin and silica fume as cement replacement material for strength performance

The cementing efficiency factor k of a pozzolan is defined as the number of parts of cement in a concrete mixture that could be replaced by one part of pozzolan without changing the property being investigated, which is usually the compressive strength. This concept was proposed by Smith [1] and was initially applied in rational proportioning of fly ash concrete by using the ‘‘fly ash cementing...
