【摘要】 将废橡胶粉以不同的方式进行表面改性,以不同比例掺入水泥砂浆,并采用纤维增强,制备了具有一定功能性的纤维增强废橡胶水泥砂浆。分析了废胶粉改性工艺、废胶粉颗粒大小、废胶粉掺量对纤维增强砂浆性能的影响。研究表明,将废橡胶颗粒进行表面改性后,可以在一定程度上提高了砂浆的力学性能,纤维和废胶粉的复合作用使得砂浆的性能有较大地改善,尤其是水泥砂浆的韧性显著增加。更多还原

【Abstract】 First waste rubber powder was modified with different approaches, then fiber reinforced rubberized mortar with a certain function was developed by adding different amount of waste rubber power and hybrid fiber. The effect of the modification technology,particle size and the amount of rubber powder on the fiber-reinforced mortar performance was analyzed. The results showed that the mechanical properties of mortar can be improved to some extent;the composite of fiber and rubber powder can largely improve the performance,in addition the toughness of fiber reinforced rubberized mortar obviously increased.更多还原
