Abstract

Eluozo SN and Dimkpa K

Monitoring the rate of micro-silica variation was carried out to determine different rate of strength developed applying various dosage, these are the pozzolanic reaction which occurs between silica fume and CH producing additional CSH in many of the voids around hydrated cement particles. This is due to high surface area of silica fume that normally affect the mobility of water within concrete segregation, this include bleeding of concrete that are virtually eliminated . This application detailed on the reactions from micro-silica reflection of it are influential factors on rapid increase of concrete strength, these are based on the mixed designed output, such application reflects the significant growth rate of concrete performance in the study, mathematical model application using analytical solution generated derived model for the study, this derived model techniques developed predictive values through simulation, the predictive were applied on the reflection of various water cement ratios including variation of micro-silica dosage numerically to ninety days of curing, water cement ratios influence of strength development were expressed in the study, variation of concrete permeability and void ratios are also detailed as an influential factor in concrete formations, the study has express its significant influence based on the developed strength within seven and ninety days of curing.
