Product Detail
1 High Range Water Reducing & Set Retarding 2 ASTM C494, Type G 3 Good effective superplasticizer with a set retarding effet

Description

JK-08NP is a water reducing, highly effective superplasticizer concrete admixture powderwith a set retarding effect for concrete in hot temperature which 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 is an ideal concrete admixture 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

It 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.Increasing initial workability. High ultimate strengths.The concrete of compressive strength, flexural, tensile, impermeability and durability are significantly be 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 timeDosage 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. Specifications
