Experimental Research on Basic Mechanical Properties of Inorganic Polymer Concrete

Abstract:

Inorganic polymer material is a new green energy-saving building material which has a broad development prospect. It has been a hot engineering research issue. In this paper, inorganic polymer concrete is made by using fly ash, mineral powder and alkaline activator. Its basic mechanical properties are studied by the cube compressive strength test, the drying-wetting cycle test and flexural strength test and compared with the ordinary concrete in the same sand ratio. The compressive strength of inorganic polymer concrete specimen with mineral powder in early days is much greater than the same level of ordinary concrete. Without mineral powder, its compressive strength has developed rapidly in the early days, but it become very slower in the later days. Furthermore, its ultimate compressive strength is less than the same level of ordinary concrete. After the drying-wetting cycles, the compressive strength of the inorganic polymer concrete specimen is lower than that of the standard conservation. The reduction rate with mineral powder is smaller. The flexural failure characteristics of inorganic polymer concrete specimen are the same with ordinary concrete. However, its bending strength is lower than the same level of ordinary concrete specimen. Research results provide valuable experimental data for the engineering application of inorganic polymer concrete.
