High-strength compressive concrete for tunnel and preparation method of high-strength compressive concrete
The invention discloses high-strength compressive concrete for tunnels and a preparation method of the high-strength compressive concrete, relates to the technical field of preparation of high-strength concrete, and provides the following scheme aiming at the problems that when high-strength concrete is mixed at present, the high-strength concrete needs to be mixed and stirred, and if the mixing effect is not good enough, the subsequent building effect is easily affected. The building block is prepared from the following components in parts by weight: 300 to 600 parts of cement, 400 to 800 parts of sand, 2000 to 3000 parts of broken stone, 30 to 50 parts of sepiolite, 60 to 100 parts of charcoal dust, 60 to 100 parts of plant fiber, 20 to 40 parts of naphthalene sulfonate water reducing agent, 300 to 500 parts of water, 20 to 40 parts of physcion and 20 to 50 parts of isooctyl nitrate. According to the device, the mixing and stirring effect can be improved, concrete attached to the bottom of the mounting plate can be scraped off, loss of raw materials is reduced, liquid raw materials can be filtered, powdery raw materials can be vibrated and screened, and the subsequent concrete mixing quality is improved.
本发明公开了一种隧道用高强度抗压混凝土及其制备方法，涉及高强混凝土制备技术领域，针对目前高强混凝土在混合时，对于其需要进行混合搅拌，如果混合的效果不够好，容易影响后续建筑效果的问题，现提出如下方案，其包括以下组分：含水泥300‑600份、砂400‑800份、碎石2000‑3000份、海泡石30‑50份、木炭粉60‑100份、植物纤维60‑100份、萘磺酸盐减水剂20‑40份、水300‑500份、大黄素甲醚20‑40份、硝酸异辛酯20‑50份。该装置不仅可以提高混合搅拌的效果，且可将安装板底部沾有的混凝土刮下，减少原料的损耗，还可以对液体原料进行过滤，以及对粉状原料进行振动筛分，提高后续混凝土混合的质量。
