MATHEMATICAL MODELING OF FLY ASH AND ALCCOFINE PARTIAL REPLACEMENTS OF CEMENT FOR HIGH COMPRESSIVE CONCRETE STRENGTH

Eluozo S. N., Afiibor B. B.

Abstract


Mathematical model was applied to monitor the behaviour of partial replacement of cement with  alccofine and flyash, alccofine and fly ash was applied to monitor the variation of strength development in different mixed designed, the study applying such concept has observed these two material to generated high strength development more than the normal strength generated applying cement in full dosage, the detailed sources of these substance  such as micro finer was observed on its particle size, this is much more finer than that of  cement, while that of flyash is a prime material as cement based product, the sources of these two materials enhanced the strength development of compressive  strength,  it was express from  the linearity of the figures that shows the rates of increase to the optimum level recorded at ninety day of curing. These condition has also shows the ductility of the material as it  displayed in the figures, the compressive strength developed was influenced by variation of simulation in mentoring water cement ratios in the study, the simulation also monitored the variation of  concrete voids and its rates of  permeability as  the effects was examined, it is observed that there is tremendous  influence on the  compressive strength increase on the developed model concrete, the study has expressed other parameters that may not have been monitored experimentally to determined there impact in strength development, these were carried out in the simulation, this is  to displayed their rates of effect in design   on model concrete partially replacing cement with alccofine and flyash., the predictive values were compared with experimental values, these parameters developed best fits correlation. The study has expressed its imperative based on the influences from various properties that has been simulated to determined their various rates of  effect, it has also  monitor the  variation of compressive strength applying two materials partially replacing cement at different water cement ratios and curing age.
