Liquid Polycarboxylic Acid High Strength Concrete Superplasticizer

Polycarboxylic acid superplasticizer is a new type of concrete superplasticizer

Polycarboxylic acid superplasticizer is the third generation of new superplasticizer for concrete. Compared with naphthalene superplasticizer, polycarboxylic acid superplasticizer has the advantages of high water reduction rate, high strength, low shrinkage, low secretion and low slump loss. Polycarboxylate superplasticizer has relatively good adaptability with different cement. Compared with naphthalene superplasticizer, the strength of polycarboxylate superplasticizer concrete increases faster in early and late periods, especially the strength of high-strength concrete increases more obviously in late periods.

Typical Applications & Advantages

This product is mainly used to formulate early strength concrete. Its main features are as follows:

(1) High water reducing rate: The dosage range is 0.3 — 0.8%. The recommended dosage is 0.5% of cementitious material.

According to ASTM C 494 type E & F “Concrete Admixtures” standard test, water reducing rate is above 28%. Water reducing rate can be above 30% under optimal dosage (confirmed by lab tests). Cement-saving rate is 15-20%.

(2) High early strength: concrete compressive strength ratio is above 180% after 1 day, above 160% after 3 days, 150% after 7 days, and 40% after 28 days, if our product is used under optimal dosage. Concrete long-term strength will also be enhanced obviously.

(3) Long durability: PC-E, with low chloride and alkali content, can decrease concrete long-term air shrinkage and shrinkage crack. Concrete shrinkage ratio will be less than 110%. Suitable air content and foaming structure will ensure concrete long durability if our product is used. It is far beyond the post-performance of both traditional naphthalene.

(4) Production clean degree is high: Due to formaldehyde, industrial naphthalene or other flammable and toxic chemicals not being used in production process, it meets cleaning production standard. This new production technology is a fully automated process without heat production.

(5) Safety: non-toxic, no radiation, non-inflammable, no corrosion for steel bar or aggregate, and no formaldehyde, or aromatic residues harmful for human. Our product complies with the current environmentally friendly standards for interior and exterior construction.

Dosage

1) Dosage range:0.3%–0.8% weight of cementitious material. (calculated according to PC-E)

2) Recommended dosage: 0.4% weight of cementitious material (calculated according to PC-E). Concrete lab test for optimal dosage is required before usage or cement changing.

Packaging, Storage and Transport

1) Our product can be packed in 200L or 1000L plastic drums according to customer’s requirements.

2) Material should be stored in a cool and dry place.

3) Shelf life is 1 year. It can also be used after shelf life if concrete test is good.

Health & Safety Precautions

Polycarboxylate Superplasticizer does not fall into the hazardous classifications for current regulations. However, it should not be swallowed or allowed to come into contact with skin and eyes. Suitable protective gloves and goggles should be worn. Splashes on the skin should be removed with water. In case of contact with eyes rinse immediately with plenty of water and seek medical advice. If swallowed, seek medical attention immediately and do not induce vomiting.

Safety Precautions

1. this product is a weak alkaline liquid, non-toxic, non-corrosive, environmentally friendly product. It is not edible and when exposed to the human body and eyes, should be washed with water as soon as possible, causing allergic to some of the human body should seek timely medical treatment.

2. this product should be stored in a covered container to avoid exposure to moisture/water and debris, mixed with or evaporation of water dry.
