Analysis of early-age behaviour of textile-reinforced cementitious matrix composites (TRC) using different measurements techniques

This study aims at investigating the early-age behaviour of textile-reinforced cementitious matrix composites. Six different configurations with two types reinforcements (glass and carbon meshes) three reinforcement layers were tested. Experimental measurements conducted using various measurement techniques: optical fibre sensors, thermocouples, thermal cameras, Fourier transform infrared spectroscopy analysis. The phases expansion shrinkage monitored during first 12 h after 15 days from casting. effects air contact, textile, mesh size grids evaluated discussed. Then, effect on mechanical tensile these composites was identified analysed. Moreover, a chemical analysis performed to determine influences constituents, cement hydration process related heat release
