Basalt fiber reinforced excavation material aggregate concrete and preparation method thereof
The invention provides basalt fiber reinforced excavation material aggregate concrete and a preparation method thereof. The basalt fiber reinforced excavation material aggregate concrete is prepared from the following components in parts by weight: 100 parts of cement, 300 parts of coarse aggregate, 226.4 parts of fine aggregate, 40 parts of water, 1 part of a water reducing agent and chopped basalt fibers, wherein the coarse aggregate and the fine aggregate are both prepared by crushing gneiss and sieving to obtain a first coarse aggregate with the particle size of 5-10 mm, a second coarse aggregate with the particle size of 10-20 mm and a fine aggregate with the particle size of 0.37-0.52 mm; in the coarse aggregate, the mixing ratio of the first coarse aggregate to the second coarse aggregate is 1: 1; wherein the volume fraction of the chopped basalt fiber is 0-0.5%, and the optimal volume fraction is 0.2%. According to the invention, the optimal fiber ratio suitable for the lining structure on the engineering site can be determined.
本申请提出一种玄武岩纤维增强开挖料作骨料混凝土及其制备方法，制备成分及成分配合比如下：水泥100份，粗骨料300份，细骨料226.4份，水40份，减水剂1份，及短切玄武岩纤维；其中，所述粗骨料和细骨料均选用片麻岩进行破碎加工，过筛获得5‑10mm粒径作为第一粗骨料，10‑20mm粒径作为第二粗骨料，0.37～0.52mm粒径作为细骨料；所述粗骨料中，所述第一粗骨料和所述第二粗骨料成分配合比例为1:1；其中，所述短切玄武岩纤维的体积率为0‑0.5％，最优体积率为0.2％。通过本发明，能够确定适用于工程现场衬砌结构的最优纤维配比。
