摘要
This paper discusses the results of a study aimed at designing cement bound mixtures for road construction, made with steel slag, ladle furnace slag, waste foundry sand, glass wastes and coal ash. The mixtures were designed by means of Proctor, compression and indirect tensile tests. Their performance was investigated in terms of elastic modulus, through ultrasonic tests at different curing times. Satisfactory results were obtained, compression and indirect tensile strength at 7 days being up to 7.56 MPa and 0.78 MPa respectively, depending on the composition of the mixtures.
