Deterministic Model on Concrete Density from Local 3/8 Gravel Influenced by Variation of Water Cement Ratios and Curing Age

Concrete densities varies base on some level of mix design, several experts has express the densities of concrete using various grades of coarse aggregate in there mix design, these study are to express the behaviour of locally occurring 3/8 gravel concrete also known as all in one aggregate 3/8 Aggregate gravel concrete. The development of concrete densities variation from experimental values compared with deterministic model simulation values were carried out in table and figures, from the graphical representation, fluctuation were observed in some values, while linear increase were express in some values, these fluctuation from the simulation values has also reflected the rate of concrete porosity varying at different water cement ratio and curing age, the heterogeneity of these densities from the predictive values are through variation from these porosity and mix proportions, water cement ratios variation were also observed to influenced the rate of concrete densities, the prediction of concrete densities at interval of seven day are the normal methods of monitoring concrete properties, but the developed model are predicting the increase of concrete densities at every twenty four hours, these method are new developed concept that can also be applied to predict other concrete parameters or properties.
