Concrete is the stuff from which we have crafted our modern societies, but this versatile and convenient building component comes with certain challenges. In the following article, we will see how polycarboxylate ether superplasticizer can be used to improve the strength of concrete.

Polycarboxylate Ether Superplasticizer

In the average urban environment, dense traffic and other constraints can mean that concrete batching plants are located a good distance from the site where concrete is being applied. This can mean that various factors in the environment can make it difficult to maintain optimal workability in the concrete. This can be made worse due to longer waiting times for mixed concrete to be delivered to a construction site — the average time for mixed concrete to make it from batching plant to the construction site is about 120- 180 minutes.

To counter long waiting times and the considerable drop in workability that can come from long waiting times and unfavorable working conditions, a suitable set of concrete admixtures have been developed to provide dispersion and retention to mixed concrete. The first of the admixtures were lignosulphonates, followed by naphthalene based superplasticizers, and finally polycarboxylate ether superplasticizers.

While the traditional naphthalene-based plasticizers are the cost-effective choice of admixture, they do not provide a sufficient advantage in creating high-performance concrete that retains workability indefinitely.

This has increased the demand for polycarboxylate ether-based admixtures, also called PCE. These hyper-plasticizers have paved the way for groundbreaking concrete technology. One of the main advantages of PCEs is that they impart better control over the rheology of concrete. This makes PCE based admixture a great solution for creating self-compacting concrete. Advanced water-reducing plasticizers use advanced PCE technology to provide advanced rheological properties to create high-performance concrete.

The performance of admixtures for concrete has been greatly improved with the introduction of many other supplemental cementing materials such as slag, fly ash, silica fumes, and others. These new components have greatly increased the scope of concrete admixtures as we see them today. In addition to many developments in the modernization of mechanized support, the dimensions of the industry have expanded to include new technologies like smart pumping of concrete.

There has also been a major shortage of skilled laborers in the industry and this has increased the need for self-compacting and smart technologies, for example, improved concrete pumps. PCEs are the new generation of concrete plasticizers, allowing workability enhancement when the ratios of water to cement are low. This allows for the production of durable concrete that will flow readily through pipes and pumps to its intended destination.

PCE Superplasticizer for Concrete

The advanced polymers in this family of concrete admixtures can produce an infinite array of variations each endowed with its special properties and specific applications. This has been especially important in the construction of skyscrapers. Nevertheless, achieving these admixtures takes skill and experience. For example, as the viscosity of the concrete increases, concrete can be harder to pump and finish. The addition of water can be used to offset this stickiness to a certain degree.

Proper mixtures, selected supplementary products, and more stable concrete mixtures and the subject of extensive research today.

PAC For Drinking Water Treatment

PAC, which is the abbreviation for Polyaluminum Chloride, is a highly efficient water treatment chemical that is used in most waste-water treatment solutions.

PAC (Polyaluminum Chloride) is used widely in both waste-water and potable water treatment since it offers enhanced coagulation efficiency. It also provides the widest range of temperature application and pH when you compare it to other types of chemicals used for water treatment.

Poly aluminium chloride powder is used widely as an effective water-treatment chemical. It also doesn’t produce a color or change the color of the water or displays any side effects when it is used.

After using PAC (Polyaluminum Chloride), the overall content of manganese, iron, and other types of heavy metals that are present in the water will be lowered. This has a minimal corrosive effect on the equipment used in waste-water treatment plants.

More importantly, PAC (Polyaluminum Chloride) that is used for projects that involve wastewater treatment features properties of adequate coagulation performance, fast setting, large-alum particle formation, high efficiency, low dosage, and a much wider application range.

PAC is a product that is frequently used for removing harmful elements that are present in water such as chromium, lead, manganese, iron, and other types of heavy metals that are not safe for human consumption. It is also useful to remove oil and fluoride present in water, which makes it useful for the treatment of dyeing, printing, oilfield sewage, papermaking, urban sludge, along with dehydration-treatment processes of sludge.

Polyaluminum Chloride or PAC 30 has a positive charge which makes it highly effective when it comes to absorbing suspended matter that is present in water. For this particular reason, PAC offers several benefits, such as robust decontamination, comprehensive efficiency in the removal of oil, and high turbidity removal. All of these benefits are available at a low cost when comparing this product to other chemicals.

PAC (Polyaluminum Chloride) when used for water treatment in most cases will ensure safety, and lower water accidents, while providing reliable and safe drinking water.

Phosphoric acid is a significant chemical used in many industries to produce a variety of products. Phosphoric acid (PA) is mildly acidic and is used in industries such as pharmaceuticals, agriculture, textile, food production, construction, cosmetics and beauty. Here are the top phosphoric acid uses:

1. Metallurgical.

Phosphoric acid is an industrial metal and is used to to treat metal surfaces by coating them with insoluble metal phosphate crystals affecting the hardness and electrical properties of the metal. Phosphoric acid is mixed with special additives and the phosphate coating is used on steel surfaces such as steel machinery, vehicles and aircrafts bodies for protection and rust proofing which ensures adhesiveness during painting.

It is also used to remove rust from metals. One only needs to soak the rusted metal object in a dilute solution of water and phosphoric acid and a reaction occurs which converts the iron oxide to ferric phosphate which can be easily removed from metals and a barrier is formed on the metal which prevents rusting and corrosion. PA is also used to remove oxides from metal machinery in food processing equipment.

2. Food and Beverage Industry.

Most products we consume make use of pure food grade phosphoric acid. It can be used as a food additive and it is mostly used as an acidity regulator in foods like jams, mayonnaise and processed meats.

In the beverage industry, phosphoric acid is used as an acidulant for juices, helps keep a check on the formation of bacteria and fungi in food processing, avoids water segregation in baked goods and can be used as food preservatives when converted to sodium and potassium phosphate. It may also be used as a disinfectant for fresh produce such as citrus fruits during processing.

3. Pharmaceutical and Dentistry Industry.

Dentists often carry out dental services and procedures using phosphoric acid derivatives such as  dental cement which is made of zinc phosphate to clean and roughen teeth before they can insert dental appliances, phosphate salts to reduce teeth sensitivity and also whiten teeth, remove plaque and clean teeth. Orthopedic implants are also covered with calcium phosphate which helps them integrate with the osseous tissues. Other phosphoric acid uses are in the making of mouth wash and anti-nausea medicine.  

4. Agriculture.

The wet-process phosphoric acid has been used for a long time in the production of fertilizers both for local and international export. The fertilizers such as superphosphates, ammonium phosphates and mixed NPK fertilizers are used either during fertilization, irrigation or foliar application. Animal and poultry feeds also contain phosphoric acid additives for flavoring and supplements.

5. Cosmetics And Beauty Industry.

Phosphoric acid uses extends to the cosmetic industry and it is used as a buffering and PH control agent in the cosmetics industry. It alters the PH of oral care and cosmetic products and it is therefore added as a stabilizing agent during formulation of personal care products and in some instances used as a preservative to lotions and creams. PA has a high UV absorbance rate and is therefore used in degrading fragrances and fatty acids in sunscreen lotions which prevents the skin from damage. Other products such as bathing products, makeup and nail products contain PA due to its buffering and PH control ability.

6. Manufacturing Cleaning Products.

Used in making soaps and detergents for cleaning tiles, tubs and toilet bowls.  It is an acid-base cleaner for tiles and natural stones surfaces. It is very effective in removing mortar residue and hard water deposits.

7. Water treatment.

Phosphates(such as stpp, sodium hexametaphosphate tech grade)are used in water treatment facilities to ensure that the quality of water by reducing lead and copper levels in the distribution system. Inorganic contaminants such as iron and magnesium if allowed to come into contact with air may discolor the water hence the phosphoric acid is used to prevent this exposure by neutralizing contaminants and preventing bacteria growth in the treatment plant.

Other phosphoric acid uses include the production of activated carbon products and acts as an electrolyte in fuel cells and oxyhydrogen generators. It is important to take precaution when handling phosphoric acid by protecting your skin, eyes and face and also ensure that there is enough ventilation to minimize respiratory risks. If you need to purchase phosphoric acid, check more from our website(, Chemate – a professional supplier of chemicals, will be your ideal choice.
