Computer Modelling and Analysis of Polymer Composite

Computer Modelling And Analysis Of Polymer Composite

concrete is a complex composite material, which begins its life as a mixture of graded stone aggregate particles suspended in a fluid of cement, water and sometimes admixtures. nominally, aggregate occupies 75% of the volume, cement about 15% and water content 10%. the priority when choosing a mix design is strength, which along

the basic parameters for the concrete ingredients mixture design are: characteristic target strength of 30 n/mm 2, cement content of 290 kg/m 3, water–cement ratio (w/c) of 0.55, fine and coarse aggregate content of 766.35 kg/m 3 and 1198.65 kg/m 3, respectively (alaneme et al. 2020a; osarenmwinda & awaro, 2009).



the mix design for the concrete was ratio 1:2:3, for ordinary portland cement (opc, cem i, 32.5n), fine aggregate and coarse aggregate respectively with a water-cement ratio of 0.5, all based on bs 1881 (1983) standard method, the fine aggregate was partially replaced with the rubber crumb at 0, 4, 8, 12, and 16% mix proportion.

this point contact ensures a low restrained shrinkage that is about 50-70% of that of conventional concrete; the reduction in voids ensures a dense concrete, and consequently a good strength can be attained.20 however, if a high-strength concrete is to be produced, care must be taken in the design of the grout as microcracking may occur owing to the settlement of the grout.
