| 摘 要： | 用Y型聚丙烯纤维和硅灰增强水泥混凝土,研究不同掺量条件下,对混凝土抗压性能的影响,并分析聚丙烯纤维以及硅灰在阻裂增强方面的作用机理.研究表明,加入聚丙烯纤维可使混凝土的抗裂、抗收缩性能提高,但会使混凝土中的孔隙率增大,使抗压强度有一定程度的降低;加入硅灰后,水泥石的密实性提高,抗压强度增大.

| Abstract: | This article used Y -shaped polypropylene fiber and silica fume to reinforce concrete. Influence of PP fiber and silica fume was quantified using compressive strength and crack growth resistance. The results show that PP fibers can raise the performance of crack growth resistance and shrinkage but with more noles which reduces the compressive strength. Adding silica fume can solve this problem and improve the density of cement. |
