Experimental Investigation on Strength and Deformation of Self compacting Concrete at Elevated Temperature

Abstract:

An unstressed test was made to study the compressive strength and stress strain curve properties of self compacting concrete (SCC), self compacting concrete with addition of polypropylene fiber (PPF), high strength concrete (HSC) under different temperatures.The relationship between compressive strength, stress strain curve and temperature of self compacting concrete was revealed.Stress strain curve function was obtained based on the experiment results, and compared with those of normal concrete (NC), high strength concrete, high performance concrete (HPC). The research results are helpful for for the establishment of constitutive model at high temperature and contributes to the design and analysis of self compacting concrete structure.

Key words:self compacting concrete; high temperature; compressive strength; stress strain curve
