Alkali-activated cementing material with low shrinkage and high seawater erosion resistance and preparation method of alkali-activated cementing material
The invention relates to a low-shrinkage high-seawater-erosion-resistance alkali-activated cementing material and a preparation method thereof. The concrete comprises the following raw materials in parts by mass: 235-245 parts of slag powder, 59-61 parts of fly ash, 95-105 parts of water glass, 20-25 parts of sodium hydroxide, 10-12 parts of calcium hydroxide, 5-6 parts of calcium nitrite, 20-23 parts of nano aluminum oxide, 5-10 parts of sodium phosphate, 1-5 parts of polyethylene glycol, 85-90 parts of water and 1200-1230 parts of standard sand. Compared with the prior art, the alkali-activated cementing material disclosed by the invention has the advantages that the shrinkage cracking resistance and the chlorine fixation performance of the alkali-activated cementing material are remarkably improved, the 28d compressive strength can reach 130MPa or above, and the economic benefit and the application prospect are remarkable.
本发明涉及一种低收缩高抗海水侵蚀碱激发胶凝材料及其制备方法，它的原材料按质量份数计包括矿渣粉235‑245份、粉煤灰59‑61份、水玻璃95‑105份、氢氧化钠20‑25份、氢氧化钙10‑12份、亚硝酸钙5‑6份、纳米氧化铝20‑23份、磷酸钠5‑10份、聚乙二醇1‑5份、水85‑90份、标准砂1200‑1230份。与现有技术相比，本发明显著提高了碱激发胶凝材料的抗收缩开裂性能和固氯性能，28d抗压强度均可达到为130MPa以上，具有显著的经济效益和应用前景。
