Building anti-freezing accelerator

Abstract

The invention discloses a antifreeze early strength admixture used in construction using concrete that includes anhydrous calcium chloride, fly ash, inositol hexaphosphate, triethanolmine, sodium benzoate, azimidobenzene, and adding monoethanolamine to adjust the pH value to 9-9.5. The advantages of the invention are that: low cost, easy to gain raw material, no toxin, and no pollution to environment; improving the compressive strength and anti-leaking, anti-charring, antifreeze ability; shortening time limit for a project; ensuring intension and saving cement content.

Description

Technical field: [0001] The invention relates to an antifreeze early strength agent used in building concrete. Background technique: [0002] At present, the antifreeze and early-strength agents used in my country's construction industry use composite materials, so the cost is high, the source of materials is few, and there is no additive that can simultaneously perform antifreeze and early-strength functions. Invention content: [0003] The purpose of the present invention is to provide a high-efficiency and low-cost antifreeze early-strength agent for building concrete, which can effectively improve the antifreeze of concrete in winter construction, and can also be used as an early-strength agent in concrete by construction units to shorten the construction period. , 3-4% of cement can be saved under the same conditions. [0004] The object of the present invention is implemented by the following technical solutions: building antifreeze early strength agent, which inclu...
