Ultra-high performance concrete admixture as well as preparation method and application thereof
The invention discloses an ultra-high performance concrete admixture as well as a preparation method and application thereof, and the ultra-high performance concrete admixture comprises the following components in percentage by mass: 35-50% of mineral powder, 20-30% of white carbon black, 15-25% of rectorite, 5-15% of hollow glass beads, 2-4% of modified latex powder, 2-4% of modified calcium sulfate whiskers, 2-4% of a synergist, 0.2-0.5% of a viscosity reducer and 0.03-0.1% of a shrinkage inhibitor. The ultra-high performance concrete admixture provided by the invention can improve the mechanical properties, working properties and later shrinkage of ultra-high performance concrete; in addition, both coarse aggregate and fine aggregate are applicable, so that the applicability is better.
本发明公开一种超高性能混凝土掺合料及其制备方法以及应用，所述超高性能混凝土掺合料，按质量百分比计，包括以下组分：矿粉35～50％、白炭黑20～30％、累托石15～25％、空心玻璃微珠5～15％、改性乳胶粉2～4％、改性硫酸钙晶须2～4％、增效剂2～4％、降粘剂0.2～0.5％以及抑缩剂0.03～0.1％。本发明提供的超高性能混凝土掺合料能够改善超高性能混凝土的力学性能、工作性能以及后期收缩；另外，粗骨料和细骨料均可适用，适用性更好。
