DESCRIPTION:
DS-J3 early-strength-type polycarboxylic superplasticizer has characteristics of high water-reducing,highslump,high enhancement,less dosage,good cement adaptability and etc. It applies to preparation of admixturesconcrete,such as commercial concrete,high strength concrete,flow concrete,self-compacting concrete,precastconcrete and etc.
Technical performances & features
1,this product is light brown red,brownish-yellow or colorless transparent liquid,products are nontoxic,nonflammable,non-corrosive,low alkali content,chlorine ions,solids content (12%~30%) ±1.
2,plastic function,the slump can be increased by 3~7cm to 20cm above,water retention,cohesiveness andsignificantly improved pumpability.
3,high slump concrete slump basic without loss of 1~2H,and is not affected by temperature changes.4,high early strength and high reinforced concrete compressive strength of ld more than 180%,and 3Dcompressive strength of concrete compressive strength of greater than 170%, 28D than 130%.
5,good applicability of cement, adapted to different types of cement, especially suitable with fly ash,slagand other active admixture compatibility with high durability of self-compacting high performance concrete.
6,good gas barrier properties,concrete air content 2%~4%,bleeding,anti-segregation good resistance ofconcrete,concrete pumping resistance is small,easy to transport.
Usage
1,the content of actual use should be determ ined by trial. 25% solids commonly used content is0. 7%~1. 5%, 12%solids is 1. 5%~2. 5%,when the preparation of high-strength concrete,increasing the content.
2,this product is not compounded with naphthalene water-reducing agent. When used with other additives,concrete compatibility testing should be carried out.
Packing & Storage
1,packing by 200kg~1000kg barrels or transporting by trucks.
2, store in a covered container, and avoid the rain and water evaporation,prevent exposure and frost
3, expiration date is 1 year. Expire products can still be used after testing qualified.
