Description
JK-08NP is a water reducing, highly effectivesuperplasticizer concrete admixture powderwith a set retardingeffect for concrete in hot temperature which delays concretesetting time. It has also high range water reducing for promotinghigh early and ultimate strengths of concrete.
JK-08NP is naphthalene-based superplasticizer compounded by someof high-performance retarder, stabilizer and reinforcing admixturesetc.
It complies with ASTM C 494 Type G, GB8076-2008 andGB50119-2003.
Uses
JK-08NP is an ideal concrete admixture for preparinghigh-performance and high-strength concrete, mass concrete andlong-distance transport concrete etc.It is suitable for workingcondition under temperature 5-40 centigrade degree.Not suitable forbeing solely applied in the steam curing concrete.Test beforeapplied in anhydrite, dross or similar industrial waste cement.
Advantage
It has a high efficiency water-reducing, retarding in the initialsetting and early strength in final setting, late-enhanced, lessslump loss etc, which is extremely beneficial to the transport andto pouring of concrete.Increasing initial workability. Highultimate strengths.The concrete of compressive strength, flexural,tensile, impermeability and durability are significantly beimproved and enhanced.The concrete setting time prolong 1-3h, itcan also be adjusted according to the user's demand. It has notaffected the strength growth of concrete at differenttimeDosage 0.5-1.2% by weight of cement. Exactdosage rates are dependent on the type of effect sought, quality ofcement and aggregates, water/cement ratio and ambient temperature.Therefore, in many cases it is advisable to carry out trialmixes.Using during mixing and after-mixing method and properlyprolong stirring time to assureeven.
