Concrete viscosity regulator

Abstract

The invention relates to the field of constructional engineering, in particular to a concrete viscosity modifier which structurally comprises the following three parts: a main chain consisting of an organic silicon structural unit A and a polyether unit B; a side chain C which is arranged on the side edge of the main chain and contains nitrogen atoms; and a borosilicate active end D which is connected to the tail ends of the main chain and the side chain. The concrete viscosity regulator overcomes the defects that a concrete viscosity regulator in the prior art cannot adapt to viscosity regulation of middle-low elevation and high-grade concrete at the same time and is narrow in application range, can be suitable for viscosity regulation of middle-low elevation and high-grade concrete at the same time, and is wide in application scene.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a concrete viscosity modifier. Background technique [0002] Concrete viscosity is a key factor affecting the performance of concrete pumping, and the development and application of viscosity modifiers are of great significance to the stability of concrete performance. Concrete viscosity modifier is used to adjust the viscosity of concrete and improve the rheology of concrete. No matter in the preparation of ordinary low-grade concrete or high-strength high-performance concrete, the application of concrete viscosity modifier can greatly improve the construction performance of concrete, and greatly improve the working performance of concrete while ensuring the mechanical properties of concrete . The research and application of concrete viscosity modifiers meet the current needs of high-performance concrete and are conducive to promoting the development of high-performance...
