Description

A kind of concrete retarder

Technical field

The invention belongs to paint additive field, relate to a kind of concrete retarder.

Background technology

In general, the large multipair cement granules of retardant and the new phase surface of hydrate have stronger active function, are adsorbed in solid particles surface, have delayed the formation of cement and paste structure.These effects can cause the hydration rate of cement to slow down, and extend the time of coagulation of cement.A large amount of heats can be released during concrete hydrating, what when summer temperature height, the temperature of goods had all reaches 80 degree, the goods produced when products temperature is too high will be no longer 5.1.8 phases, but very unstable 9.1.5 phase, and intensity is not high, the goods produced when temperature is too high there will be and return the problems such as halogen, distortion, intensity are not high.

Summary of the invention

The technical problem to be solved in the present invention is to provide one can disperse water heat-transmission amount, the concrete retarder of setting-time control.

For solving the problems of the technologies described above, hardening accelerator of the present invention comprises following integral part:

Sucrose 15-20 part, glucose 10-25 part, phosphatase 79-16 parts, Di-Sodium Phosphate 5-14 part, tertiary sodium phosphate 3-7 part, Sodium phosphate dibasic 6-9 part, trisodium phosphate 8-20 part, alkyl phosphate 9-15 part, disodium ethylene diamine tetraacetate 3-7 part, humic acid 2-9 part, Sodium Silicofluoride 5-11 part, methylene phosphoric acid derivatives 8-13 part, ethylenediamine tetraacetic methene sodium phosphate calcium 5-12 part, dimethylamine 4-9 part, formaldehyde 8-17 part, phosphorous acid 6-14 part, boric acid, sodium bicarbonate and tartrate mixture 4-12 part.

The proportionally 3:5:2 mixing of described boric acid, sodium bicarbonate and tartrate.

A kind of concrete retarder provided by the invention can disperse water heat-transmission amount, the setting-time control, has stronger active function.
