Study on Mechanical Properties of Modified Polyurethane Concrete at Different Temperatures

The objective of the present research was to study effect temperature on mechanical properties, failure mode and uniaxial compression constitutive relationship a modified polyurethane concrete. A total 24 cube 27 prism specimens were fabricated, uniformity concrete checked. compressive test, splitting tensile test static carried out at 0, 15, 40 60 °C. mode, strength, axial elastic modulus stress–strain curves obtained. Based experimental results, model considering characteristics proposed. results show that modulus, cubic strength decrease with increase temperature, peak strain ultimate significantly. When rises from 0 °C, are decreased by 67.1%, 66.4% 73.3%, respectively. calculation proposed in good agreement results. expected guide application bridge deck pavement.
