Abstract

The use of admixtures in concrete changes the mechanical properties and rheology of concrete. Reactive powdered concrete has a higher strength than ordinary concrete. In this study, the effect of adding polypropylene and metakaolin fibers on the compressive, tensile and flexural strength of reactive powder concrete separately and when these two materials are added together in reactive powder concrete, has been investigated. In this study, 69 samples have been tested to evaluate the performance of reactive powder concrete. The results show that with a 3% increase in metakaolin to reactive powder concrete, the compressive strength will increase to 23%. Adding 2% by weight of cement from polypropylene fibers to reactive powder concrete will increase the flexural strength by up to 32%. To simultaneously increase the compressive and flexural strength, the simultaneous use of metakaolin and polypropylene fibers will increase the compressive strength by up to 11% and flexural strength by up to 19%.
