Nano-modified internal-curing high-terrestrial heat-resistant full-hole slag concrete and preparation method thereof
The invention provides nano-modified internal curing high-terrestrial heat-resistant full-hole slag concrete and a preparation method thereof. The whole hole slag concrete is prepared from the following raw materials in parts by weight: 200 to 500 parts of Portland cement, 10 to 250 parts of tunnel hole slag stone powder, 900 to 1800 parts of tunnel hole slag machine-made sand, 1 to 20 parts of nano Al2O3, 0.1 to 2 parts of water-absorbent resin, 1 to 20 parts of water glass and 200 to 300 parts of water. The obtained full-hole slag concrete has the characteristics of good mechanical property, high geothermal heat resistance and the like, the problem of concrete service performance reduction caused by high geothermal heat of a tunnel can be improved, the high geothermal heat resistance use requirement of tunnel concrete is met, the concrete cracking problem caused by high geothermal heat of a tunnel structure is solved, and the service life of the tunnel structure is prolonged. And the service life of a tunnel structure building is greatly prolonged, and important practical application value is achieved.
本发明提供一种纳米改性内养护耐高地热全洞渣混凝土及其制备方法。该全洞渣混凝土包括以下重量份的原料：硅酸盐水泥200～500份、隧道洞渣石粉10～250份、隧道洞渣机制砂900～1800份、纳米Al2O31～20份、吸水性树脂0.1～2份、水玻璃1～20份和水200～300份。本发明所得全洞渣混凝土具有良好的力学性能以及耐高地热性能等特点，能够改善隧道高地热所带来混凝土服役性能下降问题，实现了隧道混凝土的耐高地热使用需求，解决了隧道结构因高地热而引起的混凝土开裂问题，使隧道结构建筑物服役寿命大幅提高，具有重要的实际应用价值。
