摘要
以28 d抗压强度为考察指标,研究了高强型水泥沥青（CA）砂浆流动性及各组分材料配合比对其抗压强度的影响.结果表明：高强型CA砂浆流动性对其成型后的密实程度有重要影响,高强型CA砂浆的扩展度宜控制在300-330 mm;高强型CA砂浆28 d抗压强度随水与水泥质量比的增大而小幅降低,随沥青与水泥质量比或砂与水泥质量比的增大而显著下降.
Effect of fluidity and material mix proportion on compressive strength of high strength cement asphalt（CA） mortar was studied based on 28 d compressive strength. It is shown that the fluidity has a strong influence on the density of high strength CA mortar. The appropriate spread diameter of high strength CA mortar should be between 300-330 mm. The compressive strength of high strength CA mortar declines to some extent with the increase of the mass ratio of water to cement, while it declines sharply with the increase of the mass ratio of asphalt to cement or mass ratio of sand to cement.
