Construction Chemical Industry: Stratagem of higher end product replacement

Construction Chemical Industry is growing at a steady rate of 17 per cent and is likely to increase its numbers, if awareness and benefits of usage of these products are portrayed to the end-users, says V.Raghunathan, Vice President, Technologies – Cerachem Pvt Limited.

Construction Chemicals or so called “sunrise industry” is growing at a phenomenal and rapid pace. Due to the low Market awareness, the use of construction chemicals is still formidably low in India and extremely small when compared to global markets due to the low market awareness.

 

 

In enhancing the quality and durability of Buildings, Construction chemicals play a Prima Ballerina role and are inevitable in adapting. There are new formulae, and significant R & D man-hours invested, which has started to pay back in selling construction chemicals

 

Fast Forward:

Construction Chemical Industry is growing at a steady rate of 17 per cent and is likely to increase its numbers, if awareness and benefits of usage of these products are portrayed to the end-users and made reach with a focussed effort. The Price (vs) Performance /The value for money to be emphasised in the Place of PRICE and there by these chemically active products can be sold at a higher platform and is expected to grow 2 times over the next 5 years.

 

How are the products distributed in terms of per cent in this sector?

Product Share (per cent of total value): A Rough Estimate:

 

Growth Barriers

(a) Absence of stringent regulations

(b) Very Poor awareness levels

(c) Very High Competition between, Global Players, MSME, SSI and low cost substitutes

(d) Claims of Price sensitization

(e) Not fully trained and skilled labour force

(f) Not using fully stipulated quality standards

 

Keys to Growth

(1) Focus in Infrastructure Investments (2) Partnership between public and private sector (3) Focus of Government (4) Geo Political factors (5) Growth of Unban suburbs (6) 20 – 25 per cent envisaged increase in RMC in the construction Industry (7) The increase in FDI (Foreign Direct Investment) (8) Better education on cost benefit Analysis (9) New Product Innovations and novelty applications etc.

 

 

Conventional Products:

AD Mixtures

 

Admixtures are added to concrete to give the end product more workability, strength and good finish

Benefits of Using Admixtures:

  • Increased concrete flow during application
  • Reinforcement of Concrete,
  • Application Ease
  • Workable time limits
  • Preventing from segregation

 

Plasticizers: which increase the workability of fresh concrete

 

Super Plasticizers: Increases the workability and are high range water reducing admixtures

 

Repair and rehabilitation Products:

Concrete jacketing, Steel Jacketing and FRP wrapping are few main rehabilitation methods by using cementitious repair mortars, concrete floor repairing systems, Polyester and epoxy-based resin mortars, moisture insensitive epoxies, structural Additives, synthetic adhesives, rust removers and corrosion inhibitors etc.,

Improvising existing old structures and reconstruction constitute the basis of these product usages with energy efficiency.

 

Water proofing chemicals: The Product designs and functions:

Water seeping is stopped by inherent mechanism of certain special chemicals in liquid, solid, slurry as well as 2 k pus, modified asphalts, clay or rubber based polymers mostly applied on the exteriors these help stop the infiltration of water.

Structural additives, synthetic adhesives, rust removers and corrosion inhibitors, polyester and epoxy-based resin mortars, moisture insensitive epoxies, are some of the chemical means used in this arena.

 

Pre-Packed Cementitious Grout: High strength, non-shrink, free flowing cementitious grout for industrial applications, used in machinery bases, structural columns, pumps and accessory bases, anchor bolts, bearing plates, floor grids, crane tracks, dowels, rail posts and sealing bolts, power line stanchions, etc.

 

Floor coatings Play a major role in the construction chemical Industry and they are lined up as below:

 

Epoxy Flooring: These are Monolithic seamless epoxy topping system offering,

 

  • Excellent chemical resistance, high flexural, compressive and tensile strengths
  • Impact and abrasion resistant

 

 

 

 Self Leveling Top Coats:

 

 Solvent free, self leveling epoxy floor topping system offering:

 

  • Abrasion resistant and durable
  • Resistant to most chemicals

 

PU clear: Two-component solvent free, polyurethane protective coating system imparts:

 

  • Excellent resistance to water ingress, UV rays, no yellowing on exposure to sunlight.
  • Excellent resistance to most industrial and atmospheric chemical attacks.
  • 100 per cent impermeable surface finish.

 

 

 

The Sealants:

 

Expansion Joint Sealant: This is a two component Polysulphide sealant and accommodates movements of joints with excellent adhesion to most construction surfaces.

 

Single component acrylic sealant:

  • Resistant to ozone and ultra violet radiations
  • High performance acrylic sealant
  • Accommodates the movements of joints

 Two component part polyurethane sealant:

  • Excellent weather resistance.
  • Low modulus and high movement accommodation of +/-25 per cent.
  • Excellent resistance to bio-degradation.
  • High performance in extreme conditions.
  • It is low in pitch, low modulus and high movement accommodation.
  • Stable in high temperature and high humidity conditions

Low modulus single component PU sealant:

  • High performances under high and low temperature condition.
  • Excellent allocation and high bond strength to the substrate.
  • UV resistance.

Polymerized flexible Joint Sealant:

  • High chemical, UV and weather resistance
  • High joint movement capacity
  • Permanently active system
  • Elongation up to 400 per cent

 

The New Horizon of “NICHE” Products

Up gradation of the Industry is already happening with Value for Money products being added frequently.

The Carbon Fibre Membranes (CFR):

CFR Membranes are uniquely formulated prefabricated carbon fibre membrane designed for tensile strength. Properly installed, forms an excellent strengthening and repair system to accommodate the stresses.
