Abstract

This study proposes to add basalt waste and polypropylene fibers in micro-concrete noting its tensile strength and compressive strength, as well as your workability. It was initially established the mix design of conventional concrete 1:2:3, the water/cement ratio 0.47 and from this developed mix designs with diferent tax of additions. Default consistency was established from the mark, which was maintained with the use of additive plasticizer. It was found that the concretes with the additions were more unctuous and easy to handle that the reference concrete, even with the same slump. There was an increase of 30% of the compressive strength compared to conventional concrete, which are deemed to be at filer effect of basalt powder and a little by the interference of the fibers in the progression of thermal cracks. There was no significant change in tensile strength. The study revealed that the materials tested are compatible on the basis of the performance presented by the mixtures, both fresh, and in the hardened state.
