Recently, the "Construction Method for Commercial Concrete under Negative Temperature Conditions" compiled by the Xinjiang Regional Headquarters under China State Construction Western Construction Co., Ltd. has been appraised as reaching the domestic leading level. This method can effectively solve many challenges in winter construction in the concrete industry.

For a long time, commercial concrete construction under negative temperature conditions has been a persistent challenge in engineering construction. Ordinary antifreeze agents, due to their high chloride ion content, have seriously affected the durability of concrete.

This method covers processes including the treatment of raw materials for concrete production and construction under negative temperature conditions, construction technology, thermal calculations, and concrete production, construction, and curing. While adding ordinary antifreeze agents, it also appropriately incorporates air-entraining agents, new polycarboxylate-based high-performance antifreeze agents, and ultrafine composite mineral admixtures, and uses low-failure-rate heat transfer oil boilers to replace the original steam boilers. This effectively improves the concrete's resistance to freeze-thaw damage under negative temperature conditions, accelerates the turnover efficiency of engineering formwork, reduces delays caused by equipment failures, and shortens the construction cycle by 20% year-on-year.
