Abstract

The invention discloses a modified polycarboxylate powder water-reducer specially used in fluid mortar, which comprises the following components in mass percent: 90.0-98.0% of the original powder of polycarboxylate water-reducer; 0.5-98.0% of superfine talc powder 5.0%; anti-adsorption agent 0.25-1.0%; high-viscosity biosynthetic collagen 0.03-0.08%; fibrillar synthetic pulp 0.3-0.5%; high polymerization retarder 0.5-2.0%. Through the above-mentioned method, the modified polycarboxylate powder water-reducer specially used in fluidity mortar provided by the present invention can improve the flow performance of the polycarboxylate water-reducer by means of effective and low-dosage additives through physical compounding , increase the spreading area of ​​the fluid mortar, prolong the release time of the polycarboxylate superplasticizer force, maintain a good construction work degree, improve work efficiency, and improve the construction quality.

Description

Technical field [0001] The invention relates to the field of concrete, in particular to a modified polycarboxylic acid powder water-reducing agent specially used in fluid mortar. Background technique [0002] Generally, polycarboxylic acid water-reducing agents are used in fluid mortars, and the time point of their effects varies with different materials. In other words, the time for the water reducing agent to exert its maximum effect is different. Some can fully take effect within 15 seconds and achieve the best flow performance. Some need to extend the mixing time to 1 minute to achieve the best flow effect. Although the dosage is the same, the application areas will be different. In particular, with the progress of society, the price of labor is getting higher and higher. Simply relying on manual labor to complete some work cannot be guaranteed in terms of efficiency and quality. This requires the use of mechanized construction, it must be matched with appropriate materials...
