Nano-micron composite concrete powder early strength agent and preparation method thereof
The invention relates to a nano-micron composite concrete powder early strength agent and a preparation method thereof. According to the designed and prepared nano-micron composite concrete powder early strength agent, the performance advantages of nano particles and micron particles are combined, the early strength agent is well dispersed in concrete by means of the form effect of fly ash particles, and the early strength effect of a nano crystal nucleus early strength agent is fully exerted; the defects that a nanocrystal nucleus early strength agent suspension system is inconvenient to transport and use, poor in stability and the like are overcome, the early strength of the concrete can be greatly improved, and the acceleration of the secondary hydration reaction of the fly ash is also beneficial to the increase of the later strength.
本发明涉及一种纳米微米复合型混凝土粉体早强剂及其制备方法。本发明设计并制备的纳米微米复合型混凝土粉体早强剂，结合了纳米粒子及微米粒子的性能优势，既借助粉煤灰颗粒的形态效应从而在混凝土中获得良好的分散，又充分发挥了纳米晶核早强剂的早强作用，改善了纳米晶核类早强剂悬浮液体系运输使用不便、稳定性不佳等不足，不仅能够大幅提高混凝土的早期强度，粉煤灰二次水化反应的加速也有利于后期强度的增长。
