The present invention relates to the field of construction engineering, in particular to a concrete viscosity modifier, which comprises the following three parts: a main chain composed of organosilicon structural units A and polyether units B; The side chain C of the nitrogen atom; the borosilicate active end D connected to the main chain and the end of the side chain. The invention overcomes the defect that the concrete viscosity modifier in the prior art cannot be adapted to the viscosity adjustment of medium-low elevation and high-grade concrete at the same time, and has a narrow application range, and can be applied to the viscosity of medium-low elevation and high-grade concrete at the same time Adjustment, the application scene is wider.
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. The development and application of viscosity modifiers are of great significance to the stability of concrete performance. Concrete viscosity modifier is used to adjust concrete viscosity and improve concrete rheology. Whether it is in the preparation of ordinary low-grade concrete or high-strength and 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 concrete...
