Polycarboxylate Superplasticizer concrete admixture (50%)
JH-50 Polycarboxylate Based Superplasticizer
JH-50 polycarboxylate based superplasticizer from Zibo Jianhua Building Materials Company is a high range and high performance water reducer which is joint researched and developed with scientific institutions.It is polymerized by a variety of polymer organic compounds and doesn’t contain the harmful substance formaldehyde.Now it becomes the most popular eco-friendly concrete admixture home and abroad.
This product has bleed air function and during its long-term storage, it doesn’t delaminate or precipitate, and has no crystallization in winter, which is especially suitable for formulating high-durability, high flowing and high strength concrete, and exposed concrete with high quality requirements.Widely uesd in hydraulic electrician, ports, bridges, highways,tunnels and other projects.

II:Main Performance
1.Low dosage:save 15-30% of cement and high water reduceing rate:from 25-40%.
2.Low Slump loss:less than 20% during 2 hours.It is beneficial to long-distance transport and pumping construction.
3.Good compatibility:can be used with various cements and admixtures.
4.Low shrinkage of concrete:can improve the compression of freshly mixed concrete.
5.Low chloride and alkali content,no corrosion to steel-bar.
6.High stability:no precipitation at low tempreture.
7.Environmental friendly and nontoxic.
8.High economic benefit:less cost in projects than use the other products.
III:Scope of Application
1.Suitable for compounding long-distance transportation pump concrete.
2.Suitable for compounding normal concrete,high-performance concrete,high-strength concrete and ultra-high strength concrete.
3.Suitable for compounding high durable concrete which has impermeability,high ability of keeping collapse and frost-resistance.
4.Suitable for compounding high-performance and high flowing concrete,self-leveling concrete,fair-faced concrete and SCC.
5.Suitable for compounding concrete which has high dosage of coal ash and mineral powder.
IV:Usage
1.The blend dosage (by weight) is 0.4%-1% of the gelled material.
2.In order to fix the best blend dosage, trial mix according to the requirements of construction is recommended.
3.This product can’t be compounded with naphthalene type water reducer. Compatibility test should be done previously when using together with other kind of admixture.
4.Measure accurately. Avoid repeat mix, missing mix and error.
5.Mud content of sand,stone and quality variety of admixtures has great effect on water reduction.So standard aggregate and admixtures are recommended.
V:Preparation Methods
1.PCE(50%) is always diluted to 10% to 20% concentration for use.
For example,to make 1 ton of PCE solution(10%),please fully dilute 200kg of PCE(50%) into 800kg of water.
2.When making pumping agent with PCE(50%),a certain amount ratarding agent,air-entraining agent and defoamer need to be added in the PCE(10%).On special occasions when slump loss of concrete speeds up and segregation appears after casting,it’s necessary to add plastic retaining agen.
HERE is the general formula to compound pumping agent.
PCE solution (10%): 980kg
Retarding Agent: 15-20kg
Air-entraining Agent: 2kg
The dosage of RMC pumping agent is 1.8-2.5% by weight of cement.
Air content of concrete should be controled between 3% to 4%.
VI:Package and Storage
1.JH-PCE is liquid,packed in plastic drums:1.1Ton/drum,210kg/drum.
2.Keep from rain and clutter with seal covering.
3.Keep out of the sun and can’t be stocked below freezing point.
4. When opening,it should be used up within 60days.
5. It can be stocked in drum a year without opening.
6.This product is valid for 1 year, but still can be used if checked qualified after 1 year.
