Concrete anti-freezing water reducing agent

Abstract

The invention discloses a concrete anti-freezing water reducing agent, and relates to the technical field of concrete. The concrete anti-freezing water reducing agent has a formula which comprises thefollowing components in parts by mass: 20 to 50 parts of a beta-formaldehyde naphthalene sulfonate condensate, 30 to 40 parts of glucose laurate, 30 to 50 parts of microcrystalline muscovite powder,15 to 30 parts of bentonite, 20 to 50 parts of triterpenoid saponin, 3 to 5 parts of an Artemisia seed gum, 5 to 8 parts of ethylene glycol and 10 to 12 parts of polysorbate. The concrete anti-freezing water reducing agent provided by the invention has the following advantages: adsorption of soil to a water reducing agent is reduced; the effects of a water reducing agent are fully exerted; the rate of water reducing is improved; compressive strength of concrete is effectively maintained; good water-reducing dispersity is achieved; compression resistance and fracture resistance of the concreteare reinforced; good anti-freezing effect of the concrete is improved; the freeze-thaw resistant durability of the concrete is improved; the concrete can be applicable to being used in engineering ofcold regions; and the water reducing agent has high strength and good performances, effectively improves the performances of the concrete, and prolongs the service life of the concrete.

Description

technical field

[0001] The invention relates to the technical field of concrete, in particular to a concrete antifreeze water reducer. Background technique

[0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The term concrete usually refers to the cement concrete obtained by mixing cement with cement as cementing material, sand and stone as aggregate, and water (may contain admixtures and admixtures) in a certain proportion, also known as ordinary concrete. Concrete, which is widely used in civil engineering.

[0003] Concrete water reducer is one of the important products in the building materials industry. Adding water reducer to the concrete mixture can disperse the cement particles, improve the fluidity of the concrete mixture, reduce the amount of cement per unit, save cement, and make the concrete resistant Frost resistance is an important part of the durability of concrete. ...
