This paper deals with fundamental studies of the resistance to wear of artificial light-weight aggregate concrete. Experimental results are presented concerning the effects on the wear of concretes of the kinds and combinations of aggregates used, water-cement ratio, cement content, and sand percentage. The conclusions obtained are as follows : (1) The artificial light-weight aggregate concrete is less resistant to wear than concretes containing relatively harder aggregates as river sand and gravel, i.e., wear loss of the former is three times as much as the latter. (2) When river sand, harder fine aggregate, is combined with light-weight coarse aggregate, the concrete is more resistant to wear than that which contains both fine and coarse artificial light-weight aggregates. (3) The resistance to wear of concrete varies inversely proportional to the water-cement ratio, and directly proportional to the compressive and tensile strength and hardness. (4) No significant correlation was found to exist between the cement content, sand percentage and the resistance to wear of artificial light-weight aggregate concretes.
