Abstract:An investigation was undertaken to evaluate the influence of different aggregates on the wear resistance of concrete floors. Three types of mixes were used: one with 3/4-inch aggregate, representing a monolithic floor; one with 3/8-inch aggregate, representing a two-coure floor; and one with fine aggregate, used as a dust coat. Ten different mineral and ground-iron aggregates were tested. An attempt was made to keep all variables except aggregates constant. These included workablity, compressive strength, and method of finishing. Abrasion tests indicated that the relative hardness of mineral aggregates was not directly related to the wear esistance of the floor, or atleast had comparitively little influence on this property. Similarly, the method of finishing, within the limits of the types of finishing used in this investigation, was only significant to a small degree. With a malleable-iron aggregate, however, marked differences in wear resistance from that observed with mineral aggregates were found.
