Alkali-free fluorine-free chlorine-free quick-setting early strength component, preparation method and application
The invention provides an alkali-free fluorine-free chlorine-free quick-setting early-strength component which comprises a component A and a component B in a mass part ratio of 1: (1-2), the component A comprises the following raw materials in parts by mass: 4-5 parts of aluminum sulfate octadecahydrate and 4-5 parts of water; the component B comprises the following raw materials in parts by mass: 1-2 parts of a nano material and 12-13 parts of water; the nano material is a mixture of nano ettringite and any one of nano silicon dioxide, nano aluminum dioxide, nano titanium dioxide and nano calcium silicate hydrate; the content of nano ettringite in the nano material is not less than 70%. The nano-ettringite in the quick-setting early-strength component is good in dispersity, and no additional dispersing agent is needed; fluorine ions are not contained, so that the harmfulness to a human body is reduced; chlorine ions are not contained, so that corrosion damage of the chlorine ions to reinforcing steel bars is effectively avoided; sodium and potassium ions are not contained, alkali-free rapid hardening is truly achieved, and the problems of strength shrinkage and durability in the later period are avoided.
本发明提供了一种无碱无氟无氯速凝早强组分，该速凝早强组分包括A组分和B组分，A、B组分的质量份数比为1:(1‑2)；A组分包括以下质量份数的原料：十八水合硫酸铝4‑5份、水4‑5份；B组分包括以下质量份数的原料：纳米材料1‑2份、水12‑13份；纳米材料为纳米钙矾石与纳米二氧化硅、纳米二氧化铝、纳米二氧化钛、纳米水化硅酸钙中的任一种的混合物；纳米材料中纳米钙矾石的含量不小于70％。本申请使用的速凝早强组分中纳米钙钒石分散性良好，无需额外分散剂；不含氟离子，降低对人体的危害性；不含氯离子，有效避免氯离子对钢筋的锈蚀危害；不含钠钾离子，真正实现无碱速凝，避免后期的强度倒缩和耐久性问题。
