บทคัดย่อ: This article presents the consideration of relation between compressive strength and rebound number of concrete cooperating with quarry dust as fine aggregate (natural river sand was replaced by quarry dust at the rate of 0%, 25%, 50%, 75% and 100% by weight of fine aggregate). The properties of the tested concrete samples are w/c = 0.6, maximum size of coarse aggregate is 20 mm., cement contents are between 308 and 348 kg/m3, slumps range from 0 to 100 mm., the 28-day compressive strength from 14 to 30 MPa. It was found that the rebound number results were affected by quarry dust especially the standard deviator of rebound number. The cube compressive strength at 28 days and the supplementary curve from the instruction manual were discussed. Moreover, the prediction equation is proposed to estimate the compressive strength of concrete cooperating with quarry dust as fine aggregate. © 2016 The Authors, published by EDP Sciences.
