摘 要:为提高砂浆拉伸黏结强度,研究了不同水泥及胶粉掺量对砂浆拉伸黏结强度的影响。结果表明:当水泥掺量较低时,增加胶粉掺量能在一定程度上提高砂浆的拉伸黏结强度;当胶粉掺量较小时,增加水泥掺量能显著提高砂浆的拉伸黏结强度;当水泥掺量与胶粉掺量均较大时,同时增大水泥与胶粉掺量会降低砂浆的拉伸黏结强度。
Abstract: In order to improve the tensile bonding strength of mortar, the effects of different cement content and rubber powder content on the tensile bonding strength of mortar were studied. The results show that when the cement content is low, increasing the rubber powder content can improve the tensile bonding strength of mortar. When the content of rubber powder is low, increasing the content of cement has obvious effect on improving the tensile bonding strength of mortar. When the cement content and rubber powder content are both high, increasing the cement content and rubber powder content will reduce the tensile bonding strength of mortar.
