Concrete Admixture, Polycarboxylate Ether

STEMOL PW-35 (PCE POWDER)
The product was powdered polycarboxylate superplasticizer with high performance of water-reducing and slump retention It has the benefits as follow:
1. High water reducing rate could achieve 25% above, under the conditions of mixing the concrete with the same ratio of the water, the product could improve fluidity greatly.
2. Liquid polycarboxylate superplasticizer is available by diluting the product with just water.
3. The index of performance for this product is the same with the index of pumping agent.
4. It is convenient during use & can meet the requirement of building plants in remote area by mixing the product with water.
5. The product has the features of uniforms particles, lower moisture content, excellent solubility, high range water reducing, high slump retention and so on.

MAIN PERFORMANCE:-
1. High water reducing rate: It could achieve 25% above, under the conditions of mixing the concrete with the same ratio of the water, the product could improve fluidity greatly.
2. High slump retention performance: Normally carboxylic groups is damaged of ordinary polycarboxylate superplasticizer by the high temperature during dry spray process, this product takes the special process so protect the carboxylic groups and achieve the excellent slump retention ability.
3. Excellent solubility and fast solvability: Due to uniform particles, the specific area is larger, so the product is dissolved quickly in the water then no impurity after dissolving
DOSAGE
0.2~0.3% of the aggregate material, it is instead of liquid polycarboxylate superplasticizer after dissolving the dosage after dissolving reference to the actual solid content of dissolving liquid.

Polycarboxylate Based Superplasticizer is the third generation concrete plasticizer which advance developed from lignosulfonate calcium type and naphthalene type plasticizer.

Sodium Naphthalene Sulfonate Formaldehyde
This product, named -naphthalene sulfonate formaldehyde condensate, is non-air entraining superplasticizer. It has good
dispersing performance to the cement particles. Compared with traditional plasticizer, it has higher water reducing rate, and good for preparing mass concrete, fresh concrete required for early strength and high strength, and precast concrete and parts. It also has good adaptability to commonly used cement, and widely used in roads, bridges, dams, power engineering, civil construction, steam and natural curing precast parts and other projects.

Advantage:
* Higher water reducing rate. By the recommended dosage, the water reducingrate can reach 15% -20%.
* Improve the workability of concrete, such as compression, long-term strength, flowability, etc., and enhance the reinforcement of steel and concrete.
* Reduce costs. In the case of maintaining the same workability and strength, cement amountcan be reduced.
* Wide adaptability, cost-effective. Good adaptability to all kinds of cement, such as Portland cement, slag cement, volcanic ash cement, etc.
* Be mother material to formulate other admixtures.(like early strength, set retarder, pumping agent, antifreezing agent).

YL-PL-WR Polycarboxylate Superplasticizer

(Water reducing type, 40-50% solid content)

* High water reduction, low dosage. The water reducing rate can reach 20%-40% with recommended dosage.
* Early and high strength. The early strengthand 28 day strength have been obviously improved.
* Low slump loss: complywith the pumping agent standard, slump loss would besignificantly reduced.
* High durability: This product can effectively
reduce the W/C ratio, improve durability.
* It can be used as a mother liquor to produce other functional admixture, such as early strengthtype, retarder, pumpingconcrete admixture, antifreezer, etc.;
* Environmentalfriendly products: the production does not pollute the environment;
* Non-corrosionon steelbar.

Yl-sg Sodium Gluconate Set Retarder

(industrial grade & food grade)

YL-SG is a set-retarding admixture, and it can
slow down the hydration of cement, prolong setting time, and extend the working life of concrete for long periods without any negative influence on the concrete quality.

Performance:

* Extend concrete initial setting time during hot weather.
* Increasethe workable time of concrete up to several hours.
* Provideflexibility in planning and scheduling of concrete pours.
* Applicable for massive concrete, precast concrete and large area construction.

Description

YL-SG is a kind of sodium polyhydroxy carboxylate. Its appearance is white or light yellow crystal powder. It is easily soluble in water, slightly soluble in alcohol, and insoluble in ether. It can be used as a retarder in concrete industry, or chelating agent in textile dyeing, metal surface treatment and water treatment industries, as steel surface cleaning agent, or glass bottle detergent.
Performance
Used as a cement additive: it can slow down the hydration of cement, prolong the setting time and extend the service life of concrete, no negative effect on quality of concrete in hot weather;
Used as steel surface cleaning agent;
Used as a special detergent for glass bottles;
Other industrial fields such as electroplating, film manufacturing, etc.

Sodium gluconate is a versatile chemical compound widely employed in various industrial applications. It is primarily recognized for its role as a chelating agent and concrete admixture. In construction, sodium gluconate is added to concrete mixes to enhance workability and reduce water content, ultimately improving the strength and durability of concrete structures. Its chelating properties make it valuable in cleaning products, as it effectively binds with metal ions and prevents them from causing stains or corrosion. Sodium gluconate is also used in the food and pharmaceutical industries, serving as a buffering agent, sequestrant, and stabilizer in various products. Its multifaceted properties contribute to its significance across different sectors.
