Polycarboxylate Ether Superplasticizer Powder in Concrete Construction


Applications NAY-P polycarboxylate superplasticizer is a new type concrete admixture for green concrete.
NAY-P polycarboxylate superplasticizer can be used in high strength concrete, high performance concrete, mass concrete and high quality flow plastic concrete.
NAY-P polycarboxylate superplasticizer is especially for concrete with 28d compressive strength not more than 100MPa.

 Polycarboxylate Ether Superplasticizer Powder in Concrete Construction


Properties

 


(1) A kind of anionic / non-ionic liquid admixture, low-chloride, low-alkali, non-toxic, free effect on ecological environment.
(2) NAY-P polycarboxylate superplasticizer has excellent water-reducing ability. can greatly reduce slump loss.
(3) NAY-P can significantly reduce 25% ~40% mixing water in concrete.
(4) High strength enhancing ability. Better performance when used together mineral admixture.
(5) No bleeding, anti-segregation, easy to pump and transport.
(6) Good appearance of hardened concrete, without water lines, big bubbles, and color difference.
(7) High durability. NAY-P polycarboxylate superplasticizer can greatly improve compactness, freeze-thaw resistance, carbonation resistance, elastic modulus and impermeability; reduce drying shrinkage and creep of concrete.
(8) A stable performance, non-precipitation.
(9) Excellent compatibility with Portland cement.


Dosage

 


The dosage of NAY-P polycarboxylate superplasticizer for normal strength and high strength concrete is typically 0.6%~1.2% and 1.2%~1.8% respectively, the recommended dosage for GB8076 standard test is 1.0%.
The amount of NAY-P polycarboxylate superplasticizer used in concrete will be slightly adjusted depending upon job requirements, such as concrete strength, variations in cement, aggregate and other job site conditions. Experiments for appropriate dosage must be carried out when changing concrete mix proportion or materials.


Usage

 

 NAY-P polycarboxylate superplasticizer can be added in concrete directly together with mixing water, or added after mixing water. Special storage and charging system are needed. Carefully clean storage, transport pipeline, dispensing equipment, and mixer.
NAY-P polycarboxylate superplasticizer can not be compound with naphthalene and anthracene water reducing admixtures. Experiment must be done when NAY-P polycarboxylate superplasticizer is used together with other chemical admixtures and mineral admixtures.

Packaging, transport and storage


(1) NAY-P is available in Powder pack: woven fabric bag with plastic liner. Net weight: 25kg±0.1kg or 50kg±0.2kg or 650kg±1.0kg.
(2) Dry and well ventilated warehouse is needed for storage. Quality guarantee of NAY-Ppolycarboxylate superplasticizer is half a year under normal conditions. If storage has surpassed thetime, test must be done to confirm the validity.
