Abstract

The paper deals with verifying the influence of glass fibres to volume changes in cement composites, especially shrinkage. The tests were conducted with different doses of glass fibres on the prism samples with size of 40 x 40 x 160 mm, which were fitted with glass contacts at their ends. The cement paste was modified by glass fibres in amount 0, 1, 2, 3, 4 and 5 % by weight of cement (replacement of cement). The effect of glass fibres on the bulk density, consistency, shrinkage and weight change was investigated. The achieved results have shown a positive effect of glass fibres on the shrinkage of cement composites, especially in the first days of measurement. The most significant impact was reflected in the higher dose of glass fibres - 4 and 5 %.
