Abstract
The invention discloses a kind of complex accelerator, by sodium sulfate, tartrate, trolamine, gypsum are formed down.The present invention fills a prescription rationally, and energy accelerate concrete process of setting improves concrete early strength, excellent performance, and 3 days ultimate compression strength of more conventional hardening accelerator improves more than 250%.
Description
Technical field:
The present invention relates to a kind of hardening accelerator for building.
Background technology:
Existing building hardening accelerator kind is a lot, but is generally also having problems aspect the raising early age strength of concrete.
Summary of the invention:
The object of the present invention is to provide a kind of good complex accelerator of early age strength of concrete performance that improves.
Technical solution of the present invention is:
A kind of complex accelerator is characterized in that: be made up of following components in part by weight:
0.1～0.3 part in 2～4 parts of tartrate of sodium sulfate
1～3 part in 0.01～0.03 part of gypsum of trolamine.
Described complex accelerator, form by following components in part by weight:
0.2 part in 3 parts of tartrate of sodium sulfate
3 parts in 0.03 part of gypsum of trolamine.
The present invention fills a prescription rationally, and energy accelerate concrete process of setting improves concrete early strength, excellent performance, and 3 days ultimate compression strength of more conventional hardening accelerator improves more than 250%.
The invention will be further described below in conjunction with embodiment.
Embodiment:
A kind of complex accelerator is mixed by following components in part by weight:
Sodium sulfate 2～4 parts of (2,3,4 parts of examples), tartrate 0.1～0.3 part of (0.1,0.2,0.3 part of example), trolamine 0.01～0.03 part of (0.01,0.02,0.03 part of example), 1～3 part in gypsum (1,2,3 parts of examples).Use makes hardening accelerator of the present invention add by 5～10% of cement amount.
Claims (2)
