摘要:
为研究粉煤灰和聚丙烯纤维掺量对混凝土抗压、抗折强度的影响,掺入为胶凝材料质量分数0、10%、20%的粉煤灰和0、0.23%、0.45%的聚丙烯纤维制备混凝土试件,并进行抗折、抗压试验。试验结果表明:聚丙烯纤维质量分数为0时,混凝土抗压强度随粉煤灰质量分数的增加而提高;聚丙烯纤维质量分数为0.23%和0.45%时,混凝土抗压强度随粉煤灰质量分数的增加而先提高后降低;同时掺入粉煤灰和聚丙烯纤维时,随着两种材料掺量的增加,混凝土的抗折强度均呈先提高后降低趋势;当粉煤灰质量分数为10%、聚丙烯纤维质量分数为0.23%时,混凝土试件抗压强度和抗折强度分别为42.5、7.2 MPa。

Abstract:
To explore the influence of incorporation amount of fly ash and polypropylene fiber on the compressive strength and flexural strength of concrete,concrete specimens with mass fractions of 0,10%,20% of fly ash,and 0,0.23%,0.45% of polypropylene fibers were prepared,respectively. Then,the flexural and compressive tests were carried out. The experimental results show that the compressive strength of concrete specimens increases gradually with the increase of fly ash incorporation amount when the polypropylene fiber mass fraction is 0,while the compressive strength first increases and then decreases with the increase of fly ash incorporation amount when the polypropylene fiber mass fractions are 0.23% and 0.45%. The flexural strength increases followed by decrease with the increase of incorporation amount when fly ash and polypropylene fiber are added at the same time. The compressive strength and flexural strength of concrete specimens are 42.5 and 7.2 MPa respectively when the mass fraction of fly ash is 10%,and the mass fraction of polypropylene fiber is 0.23%.
