The importance of construction chemicals cannot be overemphasized. The demand for construction chemicals worldwide has risen due to innovation in the construction industry. It is obvious that the rapid increase in advancement of technology in the construction industry, be it road construction developments, recreational projects, industrial jobs, residential building projects, commercial building projects, and so on needed to be sustained. Construction chemicals give an additional protection to the building and other components, thus protecting them from the assaults of negative climatic components.

What are construction chemicals?

Construction chemicals are components that are added to concrete and mortar to enhance compatibility with the structure. They are formulations used with cement, concrete or other construction materials at the time of construction to hold the construction materials together. They can be used in ongoing construction projects for speeding up the work or in new construction ventures or for repairing and retrofitting existing buildings or for enhancing durability and

providing strength to the structures. Construction chemicals are used along with various building materials at the construction site to improve workability, to increase efficiency, add effectiveness and to protect the part of any structure, or to accelerate the speed of construction work. The global construction chemical market can be categorized as; Concrete admixtures, Asphalt modifiers and protective coating.

Types of construction chemicals

1. Concrete Curing Compounds

A concrete curing agent forms a membrane over the top of the concrete slab while it cures. This stops the water near the surface of the slab evaporating too quickly, and hence helps to reduce cracking and dusting. Concrete Curing compounds are chemicals used to help prevent shrinkage cracking by reducing the evaporation of water from the concrete. A curing compound should be applied as soon as bleed water ceases to collect on the pavement surface.

2. Polymer Bonding agent:

Polymer Bonding Agent is an aqueous emulsion of a polymer and chemical admixtures. It is designed for use as a bonding agent with concrete and cement-based products in interior or exterior applications. Bonding agents are natural, compounded or synthetic materials used to enhance the joining of individual members of a structure without employing mechanical fasteners.

3. Protective and decorative coatings:

Decorative coatings are usually applied to surfaces of stationary structures such as buildings, bridges and roads, or parts of the stationary structures that include facades, pavements and pre-fabricated materials. These coatings can be used for protection as well as aesthetic purposes, while a protective coating is a layer of material applied to the surface of another material with the intent of inhibiting or preventing corrosion. A protective coating may be metallic or non-metallic. The commonly used materials in non-metallic protective coatings include polymers, epoxies and polyurethanes etc.

4. Bostik Cementone SBR Admixture

Bostik Cementone SBR is a specially modified Styrene Butadiene Copolymer Latex for cement and mortar. It toughens, waterproofs and improves chemical and abrasion resistance of renders, screeds and other cement based mixes. It is recommended for use in effluent tanks, dairies, food factories, fertilizer stores and other demanding situations. Cementone SBR is an excellent all round primer and bonding admixture.

Features

• Improves adhesion.
• Toughens floors and screeds.
• Provides superior frost, water, chemical and abrasion resistance.
• Ideal for damp and wet conditions.
• Improves flexibility, reduces cracking.

5. Mold releasing agents:

A mold release agent is applied to the mold surface to allow the composite part to be easily removed from the mold, avoiding stick-ups. Release agents may be sprayed, brushed or wiped on and some can be left on whilst others are wiped off. Mold release agents work by creating a barrier between the substrate and the surface of the mold. This barrier eliminates adhesion between the two materials, preventing mold damage and ensuring quick and easy release from the mold. The coating is applied to the surface of the mold before the substrate is cast.

6. Floor hardeners and dust Proofers:

Floor hardener is a particle form composition made in size graded specifications to be used by mixing with cement & grit/stone chips mixture to give extra hardness to the concrete floor without affecting cement chemistry.

Floor hardeners are used to prevent floors from wearing out prematurely. These products protect, preserve, and strengthen concrete flooring through a uniform curing and sealing process. Liquid concrete hardeners create a chemical reaction when applied to concrete, penetrating pores. Dust proofing, or seal coating, is an application of a thin film of asphalt oil followed by a layer of small rock, which provides a new wear surface for the road. Dust proofing protects the prior applications or asphalt on the street from becoming porous by preventing further oxidation.

7. Non shrink high strength grouts:

Non-shrink grout is a hydraulic cement grout that, when hardened under stipulated test conditions, does not shrink, so its final volume is greater than or equal to the original installed volume. It is often used as a transfer medium between load-bearing members.

8. Tile or cladding fixer

Tile or Cladding fixer is the application of one material over another to provide a skin or layer. In construction, cladding is used to provide a degree of thermal insulation and weather resistance, and to improve the appearance of buildings. Cladding can be made of any of a wide range of materials including wood, metal, brick, vinyl, and composite materials that can include aluminum, wood, blends of cement and recycled polystyrene.

9. Epoxy Coating

These can come as water or oil based solutions. They can be single or two components. Single component epoxy paints are usually oil based. Two component epoxy coatings chemicals are mixed in situ in proportions as prescribed by their manufacturers and they are quite suitable for factory, industrial or commercial building applications by dint of their excellent chemical and thermal resistant characteristic, hardness, durability, waterproofing characteristics etc.

10. Surface retarders and sealant

Surface retarders are spray-applied, water-soluble products designed to slow the set of surface mortar in concrete to expose the aggregate. These products temporarily halt the set of Portland cement at the surface while the concrete below the surface cures normally. While the Surface Sealant creates an invisible, durable, hydrophobic layer with bonding silicones to help protect against road salts, tree sap, bird lime, acid rain etc. Easy to wax over for an enhanced luster. Use after restoring your vehicle's bodywork to protect the rectified paint finish.

11. Polyester Resin:

Polyester resins are synthetic resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Maleic Anhydride is a commonly used raw. Unsaturated polyester resins either in the form of pure resin or in the compounded form with fillers find a wide range of applications. Their main applications are in the construction industry (non reinforced or glass fiber reinforced products), automotive industry, and industrial wood and furniture finishing.

Advantages of construction chemicals

It offers chemical resistance to the structure in question.

It significantly reduces the need for water and cement

It offers Smoother Surface:

Manufacturers of construction chemicals in India enable a smoother concrete surface. The form release agents are incredible compounds that promote formwork removal and also make sure the surfaces are smoother.

They add value to the structures by making them dust-proof and augment the look and feel of the structure.

It increases Durability:

Oil-based, resin-based, water-based and organic chemicals are the most common type releasing agents available on the market. These assist to enhance the concrete life and hence your one-time investment can produce long-term advantages.

Leakage Proof:

Form sealers are another type of chemical compound that is applied along the joints of form work and ensures that there is no leakage at the joints.

Very Economical:

This is another reason why building chemicals are preferred over traditional sealer methods. They are accessible at a reduced cost. Moreover, this type of chemical compound and adhesive prevents the concrete from aggressive weather conditions and thus requires very less frequent repair and maintenance.
