Concrete synergist and preparation method for same

Abstract

The invention relates to concrete synergist. Components of the concrete synergist, mixed by weight, include 8%-12% of triisopropanolamine, 25%-35% of polymeric alkylol amine, 5%-15% of modified polycarboxylic acid water reducer, 25%-35% of black liquor extractive and water. The concrete synergist, which is prepared by means of scientific proportioning and mixing of all components, is non-poisonous, free of abnormal odor, green and healthy. When concrete added with the concrete synergist is compared with traditional concrete, a concrete grade is increased on the premise of the same consumption, and 10%-15% of cement consumption is reduced on the premise of the same grade, so that pumping resistance is small during conveyance, workability of the concrete is improved, the concrete is resistant to bleeding, concrete cracks are decreased, all components of the concrete are more disperse, and the concrete is integrally uniform after hardening.

Description

Technical field: [0001] The invention belongs to the technical field of concrete materials, in particular to a concrete synergist and a preparation method thereof. Background technique: [0002] Concrete is a kind of artificial stone made of cementitious materials, granular aggregates (also known as aggregates) and water in a certain proportion, uniformly stirred, compacted, cured and hardened. It has the characteristics of abundant raw materials, low price and simple production process, and is one of the most important civil engineering materials in the contemporary era. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material. [0003] Concrete admixtures based on water reducer...

AI Technical Summary

Problems solved by technology

Research data at home and abroad show that under normal conditions, about 20-30% of the cementitious materials in concrete have insufficient hydration reactions and only play a filling role and cannot effectively exert the cement strength. On the other hand, due to different water-reducing The mechanism of the influence of the agent on the adsorption of cement is different. After being added to a certain extent, it is difficult to work on the concrete again, and a large amount of addition will inevitably increase the cost.
