Concrete composite admixture and concrete
The invention discloses a concrete composite admixture and concrete, wherein the concrete composite admixture comprises fly ash, mineral powder, silica fume, an expanding agent and a concrete viscosity modifier, and the mass ratio of the fly ash to the mineral powder to the silica fume to the expanding agent to the concrete viscosity modifier is (60-70):(70-80):(60-70):(25-35):(10-16). When the concrete composite admixture provided by the invention is applied to concrete, especially C100 concrete, the problems of high viscosity, expansion and shrinkage of the concrete can be solved at the same time, the compactness of the concrete can be enhanced, the durability and corrosion resistance of the concrete can be enhanced, and the concrete with high flow state and high working performance can be prepared; and the concrete is safe and environment-friendly, greatly reduces the detection frequency of on-site raw materials, and reduces the storage pressure of cementing materials on an engineering construction site.
本发明公开一种混凝土复合掺合料以及混凝土，所述混凝土复合掺合料包括粉煤灰、矿粉、硅灰、膨胀剂以及混凝土粘改剂，其中，所述粉煤灰、矿粉、硅灰、膨胀剂以及混凝土粘改剂的质量比为60～70:70～80:60～70：25～35:10～16。本发明提供的混凝土复合掺合料应用于混凝土中时，尤其是应用于C100混凝土中时，能够同时解决混凝土粘度高、膨胀收缩的问题，并且能够增强混凝土的密实性，增强混凝土的耐久性和耐腐蚀性，可以配制出高流态、高工作性能的混凝土，而且安全环保，大大降低了现场原材料的检测频率，减轻了工程施工现场胶凝材料的储存压力。
