JLY-02 slump retention type series is an eco-friendly new generation High performance water reducer. The molecular chain shape of PCE is comb shaped. The main chain of PCE molecular are absorbed onto the surface of the cement particles, which can effectively hinder the hydration, enhance flowability; The branch chains surrounded by cement particles play dual roles of steric hindrance and electrostatic repulsion, which is totally different from conventional water reducing agents. So the high performance polycarboxylate ether based superplasticizer has better dispersion and water reducing effect, Specially own the excellent slump retention ability.
FEATURES AND BENEFITS
■ Superior slump retention performance: Excellent slump retention performance, Specially in low slump retention loss, which assures the concrete workability while has no effect on the normal setting of the concrete.
■ High water reduction: Excellent dispersibility can provide strong water reducing effect and water reducing ratio, the initial water reducing ratio is 18%, which assures improving the concrete workability, enhancing the concrete strength and saving cement amount.
■ Production control: The water reducing ratio, fluidity retention ability and air entraining performance of this slump retention type of PCE can be adjusted by changing the molecular weight of the main chain, length,density and groups of the side chains.
■ Good cohesion: Ease of pumping, No delamination,No segregation or bleeding.
■ High flowability: Ease of placing and compaction. No segregation.
■ Superior durability: low porosity, low alkali and no chloride ion content, can increase the durability of the concrete.
RECOMMENDED FOR
■ Pumped concrete
■ High flowability concrete
■ High durable concrete
■ High strength concrete
■ Ready-mixed concrete
■ Long distance transport concrete

DOSAGE:
Dosage of JLY-02 should be decided according to the mix design, surrounding, the required water reducing rate and materials. Normal dosage is 0.7% weight of cement with a range of 0.25%-0.8%. Trial mixes should be made to determine the optimum dosage.
PRECAUTIONS:
Health: JLY-02 does not contain any hazardous substances need to be labeled.It is safe for use with standard precautions followed in the construction industry, such as use of hand gloves, safety goggles, etc.
For detailed health, safety and environmental recommendations please consult and follow all instructions on the product Material Safety DataSheet.
polycarboxylate ether based high range water reducer for construction is a new type super plasticizer developed suitable for engineering projects under various weathers and primarily for using in hot climate area, which have liquid and powder form. It’s most effective high range water reducing in the market which the reducing rate can go up to 35-40%. Because of their Low chloride and alkali content, no corrosion to steel-bar, high stability & environmental friendly and nontoxic characters, they have been warm welcomed in high strength concrete for railway, haven, traffic, bridge and electric power., got good feedback from worldwide customers. It is excellent superplasticizer in premix of construction and cast-in-place concrete.
