Effect of polypropylene fibre on cementitious mortar early shrinkage cracking using the eccentric-ring test
نویسندگان
چکیده
The effects of polypropylene fibres on mortar and cement-paste cracking were investigated using different amounts fibre fractions eccentric rings under restrained-shrinkage conditions. Eccentric-ring tests conducted to investigate early-age shrinkage cracks. characteristics restricted cementitious materials described by evaluating the time concrete mixtures that are less likely crack. Different fibre-volume significantly enhanced width, area, age cracking. Increasing water-cement ratio sand percentage increased age. eccentric-ring test showed a greater susceptibility in cement-mortar composites. mechanical strength was assessed, impact investigated.
