在混凝土中掺加聚丙烯纤维改善混凝土的抗冲击和抗开裂性能力。研究表明,根据对混凝土的不同性能要求,单独或者和减水剂同时掺加聚丙烯纤维都可以使混凝土的抗冲击和抗开裂能力得到提高,结合科研项目的研究初步探讨了聚丙烯纤维混凝土抗冲击和抗开裂能力的机理,并确定了最佳掺量。
Adulteration of polypropylene fibers in concrete to improve the impact resistance and cracking resistance of concrete. The results show that the impact resistance and cracking resistance of concrete can be improved by adding polypropylene fiber alone or with water reducer according to the different performance requirements of concrete. Based on the research projects, the effects of polypropylene fiber concrete anti-cracking Impact and anti-cracking ability of the mechanism, and determine the best dosage.
