Problems solved by technology

[0003] When the existing curing agent is used in severe cold weather conditions, it is prone to the problem of poor frost resistance, which will easily lead to cracks in the cured soil and road cracks. Therefore, a solidifying agent for civil engineering materials with better frost resistance is developed is very necessary

Abstract

The invention discloses a civil engineering material curing agent. The civil engineering material curing agent is characterized by being prepared from the following materials in percentage by weight:1.3 to 7 percent of a water reducer, 2.5 to 9 percent of an anti-seepage agent, 1.5 to 13 percent of sodium hydroxide, 1.8 to 25 percent of sodium oxide, 1.3 to 21 percent of maleic acid, 1.7 to 23 percent of silicate, 2.5 to 28 percent of a gel material, 5 to 11 percent of triethanolamine, 7 to 13 percent of a surfactant, 15 to 29 percent of water, 35 to 65 percent of cement and 20 to 45 percentof quick lime powder; the surfactant is prepared from sodium nitrite, fatty acid amide, alkylamine and acidic ammonium phosphate; the sodium nitrite, the fatty acid amide, the alkylamine and the acidic ammonium phosphate are compounded according to the ratio of (2.3 to 4.3) to (1.2 to 2.5) to (1.9 to 3.4) to (1.3 to 2.4). By adopting the civil engineering material curing agent, the problem that the anti-freezing performance of the curing agent is relatively poor under a severe cold climate is solved.

Description

technical field [0001] The invention relates to the field of civil construction materials, more specifically, to a curing agent for civil construction materials and a preparation method. Background technique [0002] Building a road is a huge project, and its own significance is also huge. It can promote economic development. However, there will be large and small problems in the process of road construction, one of which is that some loose soil layers will be encountered. The place. In order to strengthen these soft places, we often add curing agent to solidify the soil, making it suitable for building roads on it. [0003] When the existing curing agent is used in severe cold climate conditions, the problem of poor frost resistance is prone to occur, and it is easy to cause cracks in the cured soil and cracks in the road. Therefore, a curing agent for civil construction materials with better frost resistance is developed. is very necessary. SUMMARY OF THE INVENTION ...
