Binder reducing agent for high-strength concrete, and preparation method of binder reducing agent

Abstract

The invention discloses a binder reducing agent for high-strength concrete, and a preparation method of the binder reducing agent. The binder reducing agent for the high-strength concrete is preparedfrom the following raw materials in percent by mass: 5%-10% of a co-dispersed component, 8%-10% of an interface enhanced compaction component, 0.5%-1% of an emulsified component, 0.1%-0.5% of a foam control component and the balance of water; and the preparation method comprises the steps of firstly, adding the interface enhanced compaction component, the emulsified component and water into an emulsification tank, and stirring at a high speed to obtain a modified interface enhanced compaction component; and then, adding the foam control component and the co-dispersed component step by step, and evenly stirring to obtain the binder reducing agent. The binder reducing agent disclosed by the invention can effectively improve the viscosity of a high-strength concrete mixture, improves the strength of the concrete, significantly reduces water loss in a concrete curing process, reduces cracks in the concrete, and greatly improves the anti-permeability and durability of the concrete; in the premise of guaranteeing the strength of the concrete, the amount of admixture is 0.6%, and a cementing material is reduced by 5%-10%; and the preparation method is simple, low in cost and less in additive amount, and is remarkable in the effect of reducing the consumption of the cementing material, thus having remarkable economic benefit and social benefit.

Description

technical field [0001] The invention relates to the field of admixtures for concrete, in particular, the invention provides a glue reducer for high-strength concrete and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the construction industry, modern building structures tend to be large-scale and high-rise. High-strength concrete is gradually being applied in some national infrastructures due to its high strength and low weight. In order to improve the strength level of concrete, the measures of using high-strength cement, increasing the amount of cementitious materials, and reducing the water-binder ratio are generally adopted. The high consumption of cementitious materials also causes a lot of waste of resources and indirect environmental load, and the continuous consumption of cement will inevitably bring serious environmental problems. With the development of concrete technology, many concrete mixing plants are...
