Abstract

The invention discloses a concrete antifreeze and an application thereof. The antifreeze comprises the following components in parts by mass: 10-20 parts of calcium silicate hydrate, 4-8 parts of diatomite, 3.5-8.7 parts of sodium bicarbonate, 2.8-6.5 parts of aluminium sulphate, 2-5 parts of organic hydramine, 0.1-0.7 part of potassium sodium tartrate, 2.35-5.48 parts of aluminum dihydrogen tripolyphosphate, 6.4-10.5 parts of dibutyl maleate, 1.0-1.8 parts of sodium dodecyl sulfate, 2-4 parts of melamine and 8-10 parts of sodium gluconate. The antifreeze disclosed by the invention can be applied to the environment with the minimum temperature being -45 DEG C, the mixing quantity of the antifreeze is 25% of the mass of cement in concrete, under the condition of -45 DEG C, the intensity ofthe concrete after -7+28d can reach the intensity of concrete after 28 days of standard curing, and the product performance can meet the GB475 standard requirements.

Description

technical field [0001] The invention belongs to the technical field of concrete admixtures, in particular to a concrete antifreeze and its application. Background technique [0002] Concrete antifreeze is an admixture that can harden concrete at negative temperatures and achieve expected performance and sufficient antifreeze strength under specified curing conditions. It is a substance that can prevent moisture in materials from freezing at low temperatures. [0003] Antifreeze can be divided into strong electrolyte inorganic salts (chlorine salts, chlorine salt rust inhibitors, and chlorine-free salts), water-soluble organic compounds, organic compounds and inorganic salt composites, and composite antifreezes according to their composition. Compound antifreeze is widely used in the market at present. At present, there are mainly three types of concrete antifreeze produced in China: -5°C, -10°C and -15°C. When the temperature is lower than -20°C, there is a lack of corresp...
