Abstract
This paper presents a research of abrasive resistance of classic concrete and micro-reinforced concrete with two types of polypropylene fibers. Water/cement factor was varied from 0.5 to 0.7, while the content (in%) of the remaining components remained constant. An accelerated test of abrasive erosion of concrete was performed on the equipment allowing the high-velocity jet of water/sand mixture to act on the surface of the test specimens. The research results demonstrate that the abrasive resistance of concrete is in an inverse function of the water/cement factor; the concretes with higher compressive strength and higher bending strength have also the higher abrasive resistance; the micro-reinforced concretes demonstrate higher abrasive resistance in comparison to the benchmark concrete. © 2011 Elsevier Ltd.
