Description
JK-06PL is a ready-to-use aqueous solution of hydroxylated organic compounds with water reducing and set retarding for concrete. JK-06 PL is a liquid set retarding concrete admixture with a plasticizing effect. Substantial water reduction can be achieved without loss of workability. It complies with ASTM C494 Type D specifications.
Uses
JK-06 PL is recommended for use in all applications where high quality concrete with superior workability, high temperature, long hauls, ready-mix and extended set time and dense concrete is required.
Advantage
1. Extends concrete initial setting time for proper finishing without cold joint during hot weather.
2. Long-lasting control of slump loss, Reduce water without loss of workability and improved finishing characteristics.
3. Provides decreased permeability but increased durability and strength and reduced shrinkage and creep.
4. Chloride free, does not attack reinforcement.
Dosage
0.24– 0.6% 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.
