Abstract text:
The obtained results of an experimental program concerning the mechanical properties and Young modulus of a mineral matrix are presented. The composite material, which is based on mineral matrix, can be reinforced with glass fibres in order to obtain structural elements with improved behaviour under loading. To assess the optimal mixture for composite structural elements, a good knowledge of mechanical properties is needed. The experimental program was conducted at the “Gheorghe Asachi” Technical University of Iaşi, Faculty of Civil Engineering, Composite Materials Laboratory. Different mixtures have been tested during a period of six months. The testing methodology is in accordance with standard SR EN 196-1:2006. It was observed that the compressive and flexural strengths, as well as the modulus of elasticity, have slightly lower values compared to Ordinary Portland Cement (OPC) mineral matrix. However the workability of the mineral matrix with the new binder was highly improved compared to that of OPC mineral matrix.
