Silpozz and Steel Slag on Mechanical Properties of Concrete

Abstract

To counteract the problem due to global warming, many researchers were conducting and trying to use the waste byproducts of industrial to diminish the CO2 emission and utilize it as a partial replacement for ordinary portland cement (OPC). This paper summarizes the research work conducted to evaluate the properties of concrete by utilizing the supplementary cementitious material (SCM) such as silpozz and steel slag and as partial replacement of the OPC. Six concrete mixes including control mix were designed by using various proportions of silpozz and steel slag to analyze its effect on concrete for a curing period of 7, 28, and 56 days. Slump test is conducted for the evaluation of fresh concrete properties. The behavior of concrete has been evaluated by conducting different laboratory tests such as destructive (i.e., compressive strength) and non-destructive test (i.e, ultrasonic pulse velocity, rebound hammer test). The incorporation of more RHA particles tends to reduce the workability due to its high specific surface area absorbs more water. Inclusion of 20% of silpozz shows better enhancement of strength as compared to other concrete mixes.
