Abstract

The invention relates to the technical field of concrete, in particular to concrete antifreezer.The concrete antifreezer is prepared from 15-25 parts of sodium oxide, 8-12 parts of aluminum potassium sulfate, 3-6 parts of triisopropanolamine, 10-12 parts of sodium lignosulphonate, 6-8 parts of sodium carbonate, 12-18 parts of monocalcium aluminate, 3-9 parts of sodium carboxymethylcellulose, 3-5 parts of paraffin, 1-4 parts of pimacol, 2-6 parts of cerous nitrate, 10-15 parts of tea saponin, 12-18 parts of melamine, 1.8-3.8 parts of SAF-I type superplasticizer, 0.8-2.4 parts of sulphonated acetone-formaldehyde resin, 1.2-3.8 parts of modified bentonite, 0.1-0.6 part of air entraining agent and 1.8-4.8 parts of antifoaming agent.The novel antifreezing components are adopted, the alkali content is greatly reduced, concrete alkali aggregate reaction can be avoided, and the antifreezer does not precipitate or crystallize when stored at the subzero temperature; the novel components do not contain ammonia and do not pollute the environment.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a concrete antifreeze agent and a preparation method thereof. Background technique [0002] When the civil engineering industry conducts concrete construction in winter, the poured concrete is covered with thermal insulation materials to ensure the construction quality, but it is far from meeting the requirements. Antifreeze is often added to the concrete to ensure the quality of the concrete at low temperatures, while The physical properties of concrete paste are closely related to the rheological parameters of early concrete paste, and antifreeze has a great influence on its rheological parameters. [0003] Concrete antifreeze is a compound product, which can obviously improve the workability of concrete on the basis of improving the early strength, and the dosage is 2 to 5% of the total glue. When using, the dosage can be adjusted to meet the winter construction requirements...
