High-strength basalt stone powder concrete material and preparation method thereof
The invention discloses a high-strength basalt stone powder concrete material and a preparation method thereof. The high-strength basalt stone powder concrete material is prepared from a cementing material, aggregate, an additive and mixing water, wherein the cementing material is prepared from the following components in percentage by mass: 40-50% of cement and 45-65% of a high-strength basalt powder material; wherein the aggregate is composed of fine aggregate quartz sand with the fineness modulus of 2.5-3.0 and micro aggregate quartz powder with the particle size of 300-400 meshes; wherein the additive is a high-efficiency water reducing agent, the dosage of the additive is 2-3% of the mass percent of the cementing material, and the water reducing efficiency is 30% or above; the water-binder ratio is 0.14 to 0.18. The high-strength basalt powder material is prepared by taking the basalt micro powder, the white corundum micro powder and the metakaolin micro powder as main raw materials, a large amount of natural basalt and metakaolin can be utilized, and concrete meeting corresponding standard requirements can be prepared by matching with other aggregates under the action of an additive (a high-efficiency water reducing agent).
本发明公开了一种高强玄武岩石粉混凝土材料及其制备方法，由胶凝材料、集料、外加剂和拌合水组成；其中胶凝材料由以下质量百分比的组分组成，水泥40‑50％和高强玄武岩石粉材料45％‑65％；其中集料由细度模数为2.5‑3.0的细集料石英砂和粒径在300‑400目之间的微集料石英粉组成；其中外加剂为高效减水剂，其用量为胶凝材料质量百分比的2％‑3％，减水效率在30％以上；水胶比为0.14‑0.18。本发明以玄武岩微粉、白刚玉微粉和偏高岭土微粉为主要原料制备高强玄武岩石粉材料，能够大量利用天然玄武岩和偏高岭土，并能在外加剂(高效减水剂)的作用下，通过与其他集料配合，制备得到满足相应标准要求的混凝土。
