Interaction of glass fiber with paste matrix

The results of studies of the processes of interaction of fiberglass used for dispersed reinforcement of concrete with cement stone are presented. It was found that the nature of the interaction depends on the chemical composition of the fiber, the composition of the cement and the conditions of concrete hardening. It is shown that for steamed concretes it is more expedient to use finely ground basalt glass powder instead of basalt fiber. In this case, the compressive strength of the cement stone can be increased up to 2 times.
