Place of Origin: Beijing China (Mainland) | Brand Name: JIANKAI | Model Number: JK-08NP | Web: www.jkadmixture.com |
Usage: concrete additives | Appearance: Lark powder | Chloride content: None |
Description
JK-08NPis awater reducing, highly effective superplasticizer additives with a set retarding effect for concrete in hot temperaturewhich delays concrete setting time. It has also high range water reducing for promoting high early and ultimate strengths of concrete.
JK-08NP is naphthalene-based superplasticizer compounded by some of high-performance retarder, stabilizer and reinforcing admixtures etc.
It complies with ASTM C 494 Type G, GB8076-2008 and GB50119-2003.

Uses
- JK-08NP isideal concrete admixtures for preparing high-performance and high-strength concrete, mass concrete and long-distance transport concrete etc.
- It is suitable for working condition under temperature 5-40 centigrade degree.
- Not suitable for being solely applied in the steam curing concrete.
- Test before applied in anhydrite, dross or similar industrial waste cement.
Advantage
- Has a high efficiency water-reducing, retarding in the initial setting and early strength in final setting, late-enhanced, less slump loss etc.which is extremely beneficial to the transport and to pouring of concrete.
- Increases initial workability. High ultimate strengths.
- The concrete of compressive strength, flexural, tensile, impermeability and durability are significantly improved and enhanced.
- The concrete setting time prolong 1-3h,it can also be adjusted according to the user's demand. It has not affected the strength growth of concrete at different time.
Dosage
0.5-1.2% by weight of cement. Exact dosage rates are dependent on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes.Using during mixing and after-mixing method and properly prolong stirring time to assure even.
