Problems solved by technology

However, this type of operation also has certain disadvantages. This type of operation will greatly increase the viscosity of the concrete, which will cause problems such as uneven mixing and rapid loss during the concrete mixing process.
In addition, high-viscosity concrete cannot guarantee the fluidity and slump of concrete

Abstract

The invention provides a concrete viscosity reducer, relates to an external additive applied to ultrahigh-strength and ultra-large concrete, in particular to a viscosity reducer applied to the ultrahigh-strength and ultra-large concrete. The viscosity reducer is mainly prepared from coal ash, microbeads-POZZ, polycarboxylic acid, polysiloxane resin, sodium dodecyl benzene sulfonate, sodium phosphate, sodium sulfate, dihydrate gypsum and sodium gluconate. The viscosity reducer is designed by adding a lubricating component, a water reducer, an air entraining agent, a surfactant and a certain enhancing component, and the viscosity reducer can effectively reduce the viscosity of the concrete and avoid influence on various use properties of the concrete. The viscosity reducer is subjected to actual detection and is widely applied.

Description

technical field [0001] The invention relates to an external additive used in super-high-strength and super-large concrete, in particular to a viscosity reducer used in super-high-strength and super-large concrete. Background technique [0002] In recent years, with the rapid development of my country's economy and the continuous progress of the concrete field, the current concrete engineering construction and use process have higher and higher requirements for concrete performance, and super-large and super-high-strength concrete has attracted more and more attention. . In the construction process of this type of building, because the building requires ultra-high strength, it is often used in the mixing process to improve the concrete building by using high-strength cement, increasing the amount of cement, increasing the content of gel materials, and reducing the water-cement ratio. Strength of. However, this type of operation also has certain disadvantages. This type of op...
