Problems solved by technology

[0003] At present, there are few types of concrete synergists on the market. During the application process, there will be problems such as poor concrete encapsulation and rapid loss of slump over time. Many synergists make 20-30% cement that cannot function normally At the same time of sufficient hydration, the strength of cement cannot be guaranteed, resulting in the failure of rapid and widespread application of concrete synergists

Abstract

The invention belongs to the technical field of concrete admixtures, and in particular relates to a multifunctional concrete synergist, which is made of the following raw materials in parts by weight: 26-42 parts of diisopropylethanolamine, 2-8 parts of pentaerythritol, lignin sulphon 15-26 parts of sodium nitrate, 8-16 parts of cetyltrimethylammonium hydroxide, 1-6 parts of xanthan gum, 5-13 parts of alkyl glycoside, 40-80 parts of water. The multifunctional concrete synergist of the present invention can fully hydrate the 20-30% cement that cannot function normally, reduce the amount of cement, and at the same time, can also enhance the strength of concrete, improve the durability and anti-thawing performance of concrete, and improve the impermeability Sex, reduce concrete cracks, improve bleeding, and has multiple functions.

Description

technical field [0001] The invention belongs to the technical field of concrete admixtures, in particular to a multifunctional concrete synergist. 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. Concrete is the largest artificial stone, and it has an irreplaceable...
