Description

JK**3 ASP is a high range of water reducer which is a modified amino sulphonate and organic compounds withretarding effect. It contains no added chloride and meets the requirements of chemical admixture specifications for concrete: GB********8, GB*********3. It complies with ASTM C**4 Type F specifications.

Uses

1.       JK**3 ASP has the advantages of no air-introducing, low dosage, low slump loss, no chloride and no sodium sulfate crystal. At normal condition, it can be prepared for C**-C*0 high strength and high-performance concrete.

2.       It is ideal for use in prestress, precast, bridge deck or any concretewhere it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation.

3.       Applicable to the preparation of a plastic security requirement of commercial concrete, high-fluid concrete, retarder or super-retarder concrete, self-compacting concrete, mass concrete etc.

4.       Applicable in concrete precasting and steam-curing for both industrial and civil construction project.

5.       Available for base material for compound admixtures. It can be mixed with naphthalene-based superplasticizer which can achieve better water reducing rate and high strength performance.

Advantage

1.       Low dosage: 0.5 to 1.5% with high water reducing *5 to *2%.

2.       Low slump loss: It can satisfy the requirement of long time and distance transportation. It is ideal for commercial and pumping concrete.

3.       Effective durability. It has the property of high volume stability, anti-seepage and anti-freezing.

4.       Low alkali content:It can prevent alkali-aggregate reaction. When it is used in winter, there is no crystal.

5.       JK**3 ASP can make high-slump flowing concrete. It allows concrete to be produced with very low water/cement ratios at low or normal slumps.

6.       Wide applicability. It can be used with different variety of cement. Compatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash cement and Portland pozzolanic cement etc.

Dosage

The after-mixing approach can achieve better result. The dosage is added from 0.**1.5%. 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.
