Estimating the optimal mix design of silica fume

2019-2-1 An accurate model of estimating the compressive strength and optimal mix design of silica fume concrete can save in time and cost. In this study, the biogeography-based programming (BBP) was used as a symbolic regression method to predict the compressive strength of silica fume concrete, while the constrained biogeography-based optimization (CBBO) was used to estimate its optimal mix design.

Mix Design of High Performance Concrete Using Silica

A mix design procedure for HPC using silica fume and super plasticizer is formulated by ACI method of mix design and available literature on HPC. 2. As the silica fume content increases the compressive strength increases up to 15% [HPC4] and then decreases. Hence the optimum replacement is 15%.

Fly ash and silica fume concrete mix design

2017-4-8 Effect of fly ash and silica fume on concrete properties: Workability: Fly ash increases workability when compared with conventional concrete with same water content. The use of good quality fly ash with a high fineness and low carbon content reduces the water demand of concrete . Fresh concrete containing silica fume is more cohesive and less prone to segregation than concrete without silica fume. silica fume it is necessary to increase the initial slump of concrete.
