Composite materials made of glass fibre reinforced mineral matrices are nowadays utilized in both new construction elements and in strengthening solutions of deteriorated civil engineering structures. The use of such materials requires a good knowledge of their strength and stiffness properties for the corresponding design works.

An extensive experimental program has been carried out at the Faculty of Civil Engineering and Building Services of the “Gheorghe Asachi” Technical University of Iasi to reveal the usage possibilities of mineral matrix composites, relating to regular construction elements and to specialized modules in emergency conditions. The research program has included theoretical and experimental studies regarding the utilization of ecological reinforced matrix, obtained by partial substitution of the ordinary Portland cement by a hydraulic binder manufactured from industrial wastes. The mechanical strengths and the elastic moduli from composites with various mixes and fibre volume fractions experimentally established confirm the suitability of these materials to structural members subjected mainly to axial loading.
