| 摘 要： | 对经浮选脱炭后的粉煤灰进行了制备混凝土的配比试验, 研究了水胶比与粉煤灰掺量对混凝土抗折强度和抗压强度的影响, 试验结果表明, 当粉煤灰最大掺量为50%, 水胶比为0.34时, 混凝土28 d抗压强度为35.52 MPa, 达到了混凝土规定等级C30级以上, 其28 d抗折强度为4.58 MPa。

| Abstract: | In order to study the proportion of flyash that was decarburized by flotation for preparation of concrete, test was conducted on the influence of both water-to-cementitious materials ratio and dosage of flyash on rupture and compressive strength. Results show that, with the maximum dosage of flyash at 50%, water-to-cementitious material ratio at 0.34, the compressive strength and rupture strength of concrete can reach 35.52 MPa and 4.58 MPa after 28 d, respectively, which is up to the stipulated concrete grade C30. |
