Resistance to wear of fast-track Portland cement concrete

Document Type



The selected fast-track Type I Portland cement concretes were studied for resistance to wear at both opening and maturity (28 days) times. The effect of four cements contents, namely: 386, 445, 505, and 564 kg/m3 (with and without an accelerating admixture) is also ascertained. The trial matrices were examined for plastic and bulk properties, and wear resistance. Depth of wear and rate of deterioration as functions of matrix proportions and constituents, opening-time categories, and testing duration were determined. The influence of variables such as cement content, curing age, and accelerating admixture on compressive strength and abrasion resistance of the selected matrices were studied. The coefficient of variation and abrasion index for the abrasion test of the trials concrete were also examined. Lastly, the relationship between the abrasion resistance (depth of wear) and compressive strength at both opening and maturity ages were investigated.
