Glimate fine aggregate, preparation method, compound fine aggregate and application of compound fine aggregate
The invention discloses a glow fine aggregate, a preparation method, a compound fine aggregate and application thereof, the preparation method of the glow fine aggregate comprises the following steps: S1, testing the fineness modulus N of the glow fine aggregate; s2, aggregate with the particle size being 0.63-5 mm is screened out from the remaining materials, the mass fraction A (1-exp (B-N)) of the aggregate with the particle size being 0.63-5 mm is taken and finely crushed, and after mixing, the aggregate with the particle size being larger than or equal to 0.16 mm is reserved; wherein A is a glow constant, and B is a target fineness modulus of the fine aggregate of which the particle size is greater than or equal to 0.16 mm; the value range of A is 0.55-0.7, and N is greater than or equal to 2.5. According to the method, the problem that a large amount of by-products such as waste rocks can be generated by a traditional means of utilizing the glow is solved, the utilization rate of the raw materials is greatly increased by means of crushing scheme design and the like, and the generation of the by-products is reduced.
本发明公开了一种辉长岩细骨料、制备方法、复配细骨料及其应用，一种辉长岩细骨料的制备方法，包括以下步骤：S1、测试辉长岩骨料的细度模数为N；S2、筛选出余料中0.63‑5mm粒径骨料，取所述0.63‑5mm粒径骨料质量分数A(1‑exp(B‑N))并进行细碎，混合后保留粒径≥0.16mm的骨料；其中，A为辉长岩常数、B为粒径≥0.16mm的细骨料的目标细度模数；A的取值范围为0.55‑0.7，N大于等于2.5。本发明减少辉长岩废料处理难题：传统辉长岩利用手段会产生大量废石等副产物，本发明通过破碎方案设计等手段大大提高了原料利用率，减少了副产物的产生。
