Abstract
The invention discloses a liquid cement-setting retarding enhancer. The liquid cement-setting retarding enhancer comprises the following constituents: mixed alcohol, sodium nitrite, sodium gluconate, sodium tripolyphosphate, malt syrup, and triethanolamine. The liquid cement-setting retarding enhancer disclosed by the invention can be used for Portland cement to prolong the cement setting time obviously and improve the early strength and the long-term strength of the cement.
Description
technical field:
The present invention relates to cement additive technical field, particularly a kind of cement liquid slow setting toughener.
background technology:
Cement setting retarder is a kind of deferrable hydrated reaction of cement, thereby extend concrete time of coagulation, make the fresh concrete long period keep plasticity, convenient cast, improve operating efficiency, to later concrete properties, can not cause dysgenic admixture simultaneously.
Retardant kind is a lot, and conventional mainly contains: sulfonated lignin and derivative thereof, low molecular weight cellulose and derivative thereof, hydroxycarboxylic acid (salt), organic phospho acid (salt), boric acid (salt), mixture etc.The defect existing for original retardant is both at home and abroad updated, also newly developed retardant.
The material that specifically can be used as retardant has: dextrin, various types of starch, casein food grade and some protein-contg material; Also have sucrose, glucose, toramil B or sodium salt, Xylo-Mucine (CMC), carboxyethyl cellulose (CHC) and their mixture; Also have in addition mixture, Sodium hexametaphosphate 99, phosphoric acid, the di(2-ethylhexyl)phosphate of tartrate, soluble tartrate, calcium tartrate, terra alba, calcium sulfite, ferrous sulfate, boric acid, boric acid and tartaric mixture, tartrate and sodium bicarbonate to receive, tri-sodium phosphate, phosphoric acid four are received, Sodium phosphate dibasic, trisodium phosphate, alkylphosphonic acid carboxylic acid fat, disodium ethylene diamine tetraacetate, various humic acidss etc.
The fast development of building along with national basis, in series of road engineering the carrying out just in full preparation such as motorway, high ferro, because highway engineering construction is subject to the impact of condition, time, process, requires highway engineering construction must use road slow setting cement.Existing cement setting retarder effect is single, has just extended cement setting time, and the early stage and later strength of cement is not had to help.
summary of the invention:
Given this, be necessary to allocate a kind of can refinforced cement the cement liquid slow setting toughener of early stage and later strength.
A cement liquid slow setting toughener, comprises following composition: mixed alcohol, Sodium Nitrite, Sunmorl N 60S, tripoly phosphate sodium STPP, malt syrup, trolamine.
Preferably, each component content is:
Mixed alcohol 17 ~ 24%
Tripoly phosphate sodium STPP 3 ~ 10%
Sodium Nitrite 10 ~ 15%
Malt syrup 5 ~ 12%
Trolamine 14 ~ 20%
Sunmorl N 60S 20 ~ 30%.
Preferably, each component content is:
Mixed alcohol 23 ~ 24%
Tripoly phosphate sodium STPP 10 ~ 13%
Sodium Nitrite 16 ~ 18%
Malt syrup 10 ~ 12%
Trolamine 14 ~ 15%
Sunmorl N 60S 28 ~ 30%.
The present invention not only can significant prolongation cement setting time for silicate cement, improves the early stage and later strength of cement simultaneously.
embodiment:
A cement liquid slow setting toughener, comprises following composition: mixed alcohol, Sodium Nitrite, Sunmorl N 60S, tripoly phosphate sodium STPP, malt syrup, trolamine.
Preferably, each component content is:
Mixed alcohol 17 ~ 24%
Tripoly phosphate sodium STPP 3 ~ 10%
Sodium Nitrite 10 ~ 15%
Malt syrup 5 ~ 12%
Trolamine 14 ~ 20%
Sunmorl N 60S 20 ~ 30%.
In another embodiment, each component content is:
Mixed alcohol 23 ~ 24%
Tripoly phosphate sodium STPP 10 ~ 13%
Sodium Nitrite 16 ~ 18%
Malt syrup 10 ~ 12%
Trolamine 14 ~ 15%
Sunmorl N 60S 28 ~ 30%.
The method for formulating of cement liquid slow setting toughener: water filling in reactor, be heated to 40 ~ 50 ℃ standby, tripoly phosphate sodium STPP is added, stir 15 minutes; Add Sunmorl N 60S, stir 15 minutes; Add Sodium Nitrite, stir 10 minutes, with 100 object screen filtrations; Add mixed alcohol, trolamine, stir 20 minutes; Add malt syrup, stir 20 minutes, with 100 eye mesh screens, filter; Obtain cement retardative toughener finished product.
