Mechanical Properties of Reactive Powder Concrete with Various Content of Recycled Glass Powder

Abstract

The production of Reactive Powder Concrete (RPC) deals with stabilization of strength using quartz powder as one of the constituent components of RPC and high temperature of curing condition. In literature, the RPC with content of quartz powder to cement ratio of 30% and steam curing condition of 250ºC in an autoclave resulted a compressive strength of 180 MPa and quite high tensile strength. Since the quartz powder and high temperature tend to increase the production cost, this study proposes considering the recycled glass powder as a substitute material and a lower temperature of curing condition to achieve reasonable mechanical properties of RPC in compressive strength, flexural strength and split tensile strength. The aim of this study is to find out the effect of different glass powder content in the mechanical properties of RPC. The RPC with the glass powder content of 10%, 20%, and 30% of cement mass, and the steam curing condition with maximum temperature of 95ºC were conducted by the tests of compressive, flexural and split tensile strengths. The test results showed that the recycled glass powder caused the reasonable mechanical properties of RPC, in other words it can be a substitute material of quartz powder in RPC. In this study, the compressive strength with maximum value of 136 MPa was attained from the RPC with the glass powder content of 20%.
