Partial Replacement of Microsilca on Compressive Strength Concrete: Applying Predictive Model

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