C100高强钢管混凝土的生产及工程应用

Production and Engineering Application of C100 High Strength Concrete Filled Steel Tube

研究了胶材用量、水胶比和砂率对C100混凝土抗压强度的影响,并将最佳配合比应用于沈阳皇朝万鑫大厦钢管混凝土施工中。结果表明,胶材用量增加、水胶比降低都能提高C100混凝土的抗压强度,砂率的增加抗压强度先增加后减小,当胶材用量600kg/m^3、砂率40%、水胶比在0.25时,C100混凝土的抗压强度达到110MPa以上。

The effect of the cement amount, water-cement ratio and sand ratio on compressive strength of C100 concrete was studied. The optimum mix ratio was applied to the steel tube concrete construction of Shenyang Huangchao Wanxin mansion. The results show that the increase of cement amount and decrease of water-cement ratio can improve the compressive strength of C100 concrete but increased first and then decreased with the increase of sand ratio. The compressive strength of C100 concrete can reach 110MPa with the cement amount 600kg/m^3, sand ratio 40% and watercement ratio 0.25.
