Problems solved by technology

[0005] At present, the development of additives that have a synergistic effect on cement is still very imperfect. Many additives used in the cement production process in order to improve the performance of cement products and increase the strength of cement have high cost and complex composition, and they are effective in increasing the strength of cement after hardening. Not ideal, there are often contradictions in improving water retention, bond strength and compressive strength

Abstract

The invention discloses an addition agent having a synergistic effect on cement.The addition agent is prepared from, by weight, 5.4-5.8 parts of nitrilotriacetic acid, 1.8-2.4 parts of ethylene diamine tetra (methylene phosphonic acid) sodium, 2.4-2.7 parts of triisopropanolamine, 3.7-4.3 parts of acrylamide, 3.2-3.5 parts of alpha-sodium-olefinsulfonate, 3.3-3.6 parts of useless lubricating oil, 3.9-4.4 parts of lauryl sodium sulfate, 4.9-5.7 parts of urea, 2.2-2.5 parts of calcium lignosulfonate, 0.6-0.8 parts of molasses, 2.6-3.0 parts of sodium thiosulfate, 2.1-2.5 parts of a silicone lubricating agent, 1.5-1.9 parts of a fluorine-containing lubricating agent, 2.1-2.5 parts of polysorbate-80 and 2.3-2.7 parts of sorbitol.The construction efficiency can be improved effectively, price is low, the enhancing effect is remarkable, fallen dust is reduced, resources are saved, the raw materials are wide in source, and the manufacturing technology is simple.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an additive with a synergistic effect on cement and a preparation method. Background technique [0002] The cost of producing cement is getting higher and higher, and the profit margin is getting less and less. Behind the large-scale production of the cement industry, many manufacturers have adopted reorganization and alliances, strong alliances, new technologies and new processes, and increased clinker strength or increased mixing materials. Dosage, to save energy and reduce consumption, reduce production costs. However, based on the existing cement process conditions, it is impossible or not worth the gain to increase the amount of mixed materials, and adding 1-2% reinforcing agent to the cement can increase the three-day and twenty-eight-day strength by 3-5Mpa on the existing basis. The combined material is increased by more than 5%, and the effect is remarkable an...
