聚丙烯纤维及聚合物乳液对砂浆抗冲击性能的影响

Effects of Polypropylene Fiber and Polymer Emulsion on Impact Resistance of Cement Mortar

研究了聚丙烯纤维聚合物砂浆的抗冲击性能。实验表明,单独掺加聚丙烯纤维或聚合物乳液能有效改善砂浆的抗冲击能力,同时掺加聚丙烯纤维和聚合物乳液更能改善其抗冲击能力。初步探讨了聚丙烯纤维和聚合物提高砂浆抗冲击性能的机理。

Impact resistance of polypropylene fiber/polymer emulsion reinforced cement mortar was studied. Testing results showed that either addition of polypropylene fiber or polymer emulsion could effectively improve impact resistance of the mortar while both addition of them would even more improve its impact resistance. Mechanism of improving impact resistance of mortar by addition of polypropylene fiber and polymer emulsion was discussed initially.
