纤维增强磷酸钾镁水泥砂浆力学性能研究
Research on mechanical properties of fiber reinforced magnesium-potassium phosphate cement mortars
摘要
Abstract
The mechanical properties of magnesium-potassium phosphate cement mortars with three fibers (PVA fiber,PP fiber,glass fiber) and different ws/c have been investigated.The results show that the three kinds of fibers can enhance the mechanical properties of magnesium-potassium phosphate cement mortars in a certain extent.All of them have larger influence on the early mechanical properties of magnesium-potassium phosphate cement mortars,but the effect on the subsequent mechanical properties is decreasing.Among them,the most obvious enhancement effect is resulted from PVA fiber,and the second one is from PP fiber,while the weakest influence is for the glass fiber.Meanwhile,with the same fiber,ws/c is not the main influence factor regarding the flexural strength of the magnesium-potassium phosphate cement mortars,while the compressive strength increases with the rising ws/c.关键词
