Accelerating agent with good adaptability to cement with low alkali content and use method of accelerating agent
The invention relates to an accelerator with good adaptability to cement with low alkali content and a use method of the accelerator. The accelerator comprises the following components in parts by weight: 20-75 parts of calcined alunite, 2-6 parts of sodium carbonate, 20-70 parts of calcined shell and 3-40 parts of diatomite. The use method is as follows: when the accelerator is used for spraying concrete, the mixing amount of the accelerator is 3-8% of the mass of low-alkali cement. Compared with the prior art, the concrete spraying agent is suitable for spraying construction of concrete prepared from cement with the alkali content smaller than or equal to 0.5%, has the advantages of being good in cohesiveness, rapid in setting and hardening, low in rebound rate, ideal in strength development speed and the like, and is suitable for open-air concrete spraying construction engineering such as mountain slope protection and pit backfilling.
本发明涉及一种与含碱量低的水泥适应性好的速凝剂及其使用方法，速凝剂包括以下重量份组分：煅烧明矾石20‑75份，碳酸钠2‑6份，贝壳煅烧物20‑70份，硅藻土3‑40份；使用方法为：速凝剂用于喷射混凝土时，其掺量为低碱水泥质量的3‑8％。与现有技术相比，本发明适用于含碱量小于等于0.5％的水泥所配制混凝土的喷射施工，具有粘聚性好，凝结硬化快，回弹率低，强度发展速度理想等优点，本发明适用于山体护坡、矿坑回填等露天混凝土喷射施工工程。
