Experimental study on tensile strength development of concrete with manufactured sand

摘要

Concrete with manufactured sand (MSC) is a potential environmental friendly building material. As the limited study on tensile strength development of MSC, the findings of research work are presented in this paper. The MSC cubes were tested by the splitting tensile method, the influences that the water-cement ratio and the stone powder content have on the tensile strength development of MSC were analyzed. Test results showed that manufactured sand with no more than 13% stone powder content was beneficial to the long-term tensile strength of MSC. Forecast models are suggested for the prediction of long-term tensile strength of MSC. (C) 2017 Elsevier Ltd. All rights reserved.
