Modeling Fly Ash and Alccofine Partial Replacement of Concrete Density for High Strength Development

Abstract

This paper monitor the development of density from concrete model partially replaced cement with alccofine and fly ash, the study were generated applying modeling techniques, this concept were adopted to detail the influence of other concrete properties that influenced the growth rate of concrete density generated from such model concrete. Linear influences were observed in all the figures, the study observed variations of growth rate in the study, these are based on the mixed proportion at various dosage of the two additives partially replaced cement in the development of the concrete, this generated variation at different densities in the study. The studied developed predictive values numerically to ninety days of curing, the study has express the refection of density relating to strength development, this were thoroughly observed on the modeling techniques applied, variation of concrete void, permeability and porosity reflected various effect on the growth rate of the density. A denser concrete generally provides higher strength and fewer amount of voids and porosity. Smaller voids in concrete were observed, this also lead to less permeable to water and soluble elements. The properties of concrete such as void and porosity generated decrease growth rate as it pressured the density, the concrete density observed low permeability to water and soluble element, these effect on density of concrete is a measurement of concrete's solidity The simulation applied has explained other parameters that may have not been determined in experimental generation of concrete density; the development of concreted density has expressed the rate of model prediction that reflects variation of strength development on concrete density.
