Abstract

The invention provides a water reducing agent as well as a preparation method and application thereof. The invention relates to the technical field of concrete admixtures. The water reducing agent ismainly prepared from polycarboxylic acid, a defoaming component, an air entraining component, a water retention component, a retarding component and water according to a specific content ratio. The raw materials are reasonably matched with one another so as to realize the synergistic effect; according to the present invention, with the application of the prepared water reducing agent in the machine-made sand-containing concrete, the workability, the wrapping property and the pumping property of the machine-made sand-containing concrete can be improved, and the strength of the machine-made sand-containing concrete can be improved so as to effectively alleviate the problem that the application effect of the existing water reducing agent in the machine-made sand-containing concrete is not ideal.

Description

Technical field [0001] The invention relates to the technical field of concrete admixtures, in particular to a water reducer and a preparation method and application thereof. Background technique [0002] In recent years, due to the consideration of construction and economic costs in special fields, it has become more and more common for machine-made sand made from slate and metamorphic sandstone to be used in concrete configuration. However, for this type of concrete containing machine-made sand, due to the irregular edges and corners of the machine-made sand and the high content of flake particles, it seriously affects the workability of the prepared concrete. During the flow of the concrete, the slurry cannot drive the stones to flow at the same time, and the package is poor. Poor pumpability. Therefore, it has become very necessary and urgent to improve the workability, wrapping and pumpability of concrete containing machine-made sand, and to increase the strength of concret...
