High-strength non-shrinkage concrete master batch

Abstract

The invention relates to a construction material, in particular to a high-strength non-shrinkage concrete master batch, and aims to solve the problems that: the conventional concrete production process is relatively complex and has high technical threshold; the conventional material is not suitable to be purchased and stored on a large scale because the strength of the conventional material is influenced by storage time and storage environment; and the produced product has poor high fluidity under the condition of high viscosity, and can generate segregation phenomenon when the proportion of the water is larger. The technical scheme adopted by the invention to solve the technical problems is that: mixing 9.5 percent of high-efficiency water reducing agent melamine, 76.1 percent of UEA swelling agent, 0.6 percent of antifoaming agent, 0.6 percent of methyl cellulose ether, 12.2 percent of calcium formate and 1.0 percent of subdivisible emulsion powder; sufficiently and uniformly stirring the mixed materials; grinding the obtained product in a ball grinding mill; and selecting the ground particles of which the particle diameter is controlled to between 5 and 10mu m as the master batch. The master batch is used together with portland cement, fast setting and hardening cement, sulphoaluminate early strength cement and quartz sand to produce various concretes with different application.

Description

technical field [0001] The invention relates to a building material, in particular to a high-strength non-shrinkage concrete masterbatch. Background technique [0002] At present, due to the needs of construction and production, there are many types of concrete products (such as high-strength non-shrinkage grouting materials, cement self-leveling materials, inorganic steel anchoring materials, various cement grouting materials, and such as emergency repair materials, track mastic, and primary cement) Materials, various high-density concrete and other special-purpose concrete), every time a product of a specification is produced, the material must be purchased according to the material composition and ratio of the produced concrete, and the strength of the original material is affected by the storage time. The influence of storage and storage environment will change greatly, so it is not suitable to purchase and store in large quantities. [0003] In addition, the previous p...

[0002] At present, due to the needs of construction and production, there are many types of concrete products (such as high-strength non-shrinkage grouting materials, cement self-leveling materials, inorganic steel anchoring materials, various cement grouting materials, and such as emergency repair materials, track mastic, and primary cement) Materials, various high-density concrete and other special-purpose concrete), every time a product of a specification is produced, the material must be purchased according to the material composition and ratio of the produced concrete, and the strength of the original material is affected by the storage time. The influence of storage environment and storage environment will change greatly, so it is not suitable to purchase and store in large quantities

[0003] In addition, the previous production process is relatively complicated, the technical threshold is high, and the products produced have poor fluidity under high viscosity, and segregation will occur when the ratio of water is too large.
