Resistance of polymer concrete to high temperature

الملخص EN

In this study, the behavior of epoxy polymer concrete under various temperatures, and percent of epoxy was investigated.

The mechanical properties such as, splitting tensile strength, and compressive strength are evaluated under working conditions.

Results of (120) specimens with different shapes which represented concrete specimens having compressive strength ranging from (14.5 MPa to 31.5 MPa), and splitting tensile ranging from (1.52 MPa to 3.18 MPa) .The results are compared with the conventional (without polymer admixture) concrete.

The results showed that the compressive and splitting tensile strengths reduce when exposed to high temperature, but the use of epoxy resin apparently led to decrease the loss of the compressive and splitting tensile strengths at this condition.

The optimum dosage of epoxy resin can be give best mechanical properties for concrete was (7 % by weight of cement).

Also there is a different between the percent of reduction in the compressive strength at 700 Cο with respect to strength at 200 Cο and the percent of reduction in the splitting tensile strength at the same condition.
