High-crack-resistance and high-flow-state C100 ultrahigh-strength concrete and preparation method thereof
The invention provides high-crack-resistance and high-flow-state C100 ultrahigh-strength concrete. The ultrahigh-strength concrete is prepared from the following raw materials in parts by mass: 380-480 kg/m < 3 > of cement, 30-80 kg/m < 3 > of silicon powder, 30-80 kg/m < 3 > of fly ash microspheres, 124-160 kg/m < 3 > of mineral powder, 694-845 kg/m < 3 > of sand, 754-902 kg/m < 3 > of gravel, 6-10 kg/m < 3 > of slaked lime, 5.0-8.0 kg/m < 3 > of a modifier, 13-24 kg/m < 3 > of acrylic emulsion, 0-78 kg/m < 3 > of steel fibers, 30-60 kg/m < 3 > of an anti-crack agent, 12-20 kg/m < 3 > The invention also provides a preparation method of the ultrahigh-strength concrete. The invention aims to utilize the specific requirements and functional characteristics of the raw materials for reasonable compatibility, realize the unification of ultrahigh strength, high fluidity and high crack resistance of the concrete, and endow the ultrahigh-strength concrete with excellent working performance, mechanical property, crack resistance and durability.
本发明提供了一种高抗裂与高流态C100超高强混凝土，该超高强混凝土由以下质量配合比的原料组成：水泥380～480kg/m3、硅粉30～80kg/m3、粉煤灰微珠30～80kg/m3、矿粉124～160kg/m3、砂694～845kg/m3、碎石754～902kg/m3、熟石灰6～10kg/m3、改性剂5.0～8.0kg/m3、丙乳13～24kg/m3、钢纤维0～78kg/m3、抗裂剂30～60kg/m3、高性能减水剂12～20kg/m3、水105～133kg/m3。本发明还提供了上述超高强混凝土的制备方法。本发明旨在利用各组成原材料的特定要求及功能特性进行合理配伍，实现了混凝土超高强度、高流动性与高抗裂性的统一，赋予了超高强混凝土优异的工作性能、力学性能、抗裂性能及耐久性能。
