The Influence of Glass Fibers as Dispersed Reinforcement on Hydric Properties of Concrete

Abstract

In this paper, the effect of different kind of glass fiber on hydric properties of ultra-high performance concrete and normal strength concrete is determined. It was the use several types of micro fine high-dispersible alkali resistant fibers that prevent the formation of shrinkage cracks caused by tensions. Comparative measurements with both concrete without glass fibers are done as well. The main aim of this experimental work is to obtain sufficiently accurate input data for the estimate of durability surface layers of concrete which are connected with water transport and its accompanying effects such as biological degradation, water soluble salt transport or degradation by rainwater absorbing oxides of sulfur and carbon from air.
