Concrete Admixture – Polycarboxylate Superplasticizer of Ultra Early Strength PC-E

 

Polycarboxylate Superplasticizer of Ultra Early Strength

PC-E (primary liquid)

 

Description

PC-E is a polycarboxylic ether (PCE) based superplasticiser that has super retention technology. PC-E provides exceptionally good early strength development. While conventional admixtures for high early strength concomitantly suffer from high work-ability loss over time and eventually lower final strength, PC-E overcomes this dependency and provides much improved slump retention and vastly increased final strength of concrete.

PC-E Polycarboxylate Superplasticizer of High Early Strength is suitable for making precast concrete elements with rheoplastic concrete having fluid consistence, no segregation and low water cement ratio, and consequently high early and long-term strengths.

Standards Compliance

PC-E Polycarboxylate Superplasticizer of High Early Strength complies with the requirements of the following standards: ASTM C 494, Type E & F. BS EN 934-2.

Typical Properties

Special Features

PC-E offers the following benefits for the precast concrete industry:

-Extremely high-water reduction

-High early strength development

-Shorter demoulding time

-Energy-saving (reduced steam curing)

-Produce Rheoplastic and Rheodynamic concrete having a low water to cement ratio

-Optimize the curing cycles by reducing curing times or temperatures

-Eliminate heat curing

-Eliminate the energy required for placing, compaction and curing

-Increase productivity

-Improve surface appearance

-Produce durable precast concrete elements as per EN 206-1

As compared with the traditional superplasticizers, the engineering properties such as early and ultimate compressive and flexural strengths, bond to steel, modulus of elasticity, shrinkage, creep, and impermeability are greatly improved.

Usage

1) PC-E can be widely used in ordinary concrete and high-performance concrete, especially having excellent performance in high-performance concrete of early strength.

2) PC-E can be applied to industrial and civil construction, pumping concrete construction in hydraulic projects, ports, traffic, municipal and railways. It can also be used for making special concrete, such as high strength, ultra-high strength, high impermeability, early strength, self-leveling and steel fiber types.

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 and acetone sulfonate formaldehyde early strength superplasticizers.

(4) Production clean degree is high: Due to formaldehyde, industrial naphthalene, acetone 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.
