Quick-setting environment-friendly alkali-activated cement-based low-carbon concrete and preparation method thereof
The invention provides quick-setting environment-friendly alkali-activated cement-based low-carbon concrete and a preparation method thereof.The alkali-activated cement-based low-carbon concrete is obtained by mixing the following raw materials in parts by mass: 16-30 parts of an alkali activator, 100-180 parts of coarse aggregate, 65-120 parts of fine aggregate, 15-28 parts of fly ash, 35-65 parts of slag and 10-18 parts of water, the alkali activator comprises sodium hydroxide and water glass; 1-2 parts of sodium hydroxide and 15-28 parts of water glass; the coarse aggregate is medium-particle-size stones and small-particle-size stones; the medium-particle-size stones are broken stones with the particle size of 10-20 mm, and the small-particle-size stones are broken stones with the particle size of 5-10 mm; the fine aggregate is coarse sand and fine sand. According to the present invention, the rapid coagulation of the concrete can be achieved, the concrete can be used for the rapid hardening of emergency engineering and muddy roads, the rapid passing of emergency rescue and disaster relief vehicles is convenient, the industrial wastes such as slag and fly ash are utilized, the waste material is turned into the valuable, the harm is turned into the treasure, and the application prospect is huge.
本发明提供了一种速凝环保的碱激发水泥基低碳混凝土及其制备方法，碱激发水泥基低碳混凝土由按照质量份计的以下原料混合得到：16‑30份碱激发剂、100‑180份粗骨料、65‑120份细骨料、15‑28份粉煤灰、35‑65份矿渣、10‑18份水，其中，所述碱激发剂包括氢氧化钠和水玻璃；氢氧化钠1‑2份，水玻璃15‑28份；所述粗骨料为中粒径石子和小粒径石子；所述中粒径石子为10‑20 mm的碎石，所述小粒径石子为5‑10 mm的碎石；所述细骨料为粗砂和细沙。本发明可以实现混凝土的快速凝结，可用于抢险工程，较为泥泞的道路快速硬化，便于抢险救灾车辆的快速通行，同时利用了矿渣与粉煤灰这类工业废料，变废为宝、变害为宝，应用前景巨大。
