The Effect of Silica Fume on the Properties of Concrete as Defined in Concrete Society Report 74, Cementitious Materials
نویسنده
چکیده
The new Concrete Society Publication, Cementitious Materials, CSTR74, covers the effects of cementitious materials blast furnace slag (GGBS), fly ash (FA), limestone fines and silica fume (microsilica) on the properties of concrete. This paper focuses on the effects of silica fume on all the main properties of concrete in the fresh and hardened state as defined in the publication.

Effect of Limestone Powder on Compressive Strength of Concrete Containing Silica Fume and Optimization of Mix Design Using Response Surface Method
Silica fume has been largely used in concrete in recent decades due to its effect on improvement of strength and durability of concrete. On the other hand, attention has been recently paid to the use of limestone powder as a substitute for part of cement in concrete, basically because of its low price and its positive effect on the durability of concrete. The aim of the current study is the i...

متن کاملAn Investigation of Coarse Aggregate, Water-Cement Ratio, and Silika Fume on Frost Resistance of HS Concrete
It is well known that the characteristics of concrete components greatly affect the durability of high strength/high performance (HS/HP) concrete against frost action. Undoubtedly, precise recognition of this relationship leads to appropriate selection of the type and proportions of concrete components in any particular project. In the current study, the aim is to investigate the possibility ...

متن کاملThermodynamical and Experimental Study of the Effects of Ball Clay-Silica Fume Combination on the Hydration and Strength
The production of ordinary Portland cement (OPC) as the most expensive constituent of concrete is associated with destructive environmental effects and significant energy consumption. Thus, the use of supplementary cementitious materials such as Natural or synthetic pozzolans is a fundamental solution that affects the kinetics of hydration of cementitious materials. In this article, to evaluate...
