Hardcon

DESCRIPTION:

AT-HARDCON exhibits unique ‘dual property’ of concrete floor hardener and sealer; available in liquid form. AT-HARDCON has the special characteristic of changing the chemical composition of treated surface(s) by filling the pores and capillaries of the concrete matrix with a hard dense gel like structure. AT-HARDCON is a concrete densifier & chemical hardening compound. It is a proprietary, water-based, ready-to-use, clear silicate liquid, formulated with chemically reactive raw materials to harden and dustproof the concrete. This waterborne solution, when properly applied, offers substantial improvement in abrasion and chemical resistance and will significantly improve the durability of the concrete surface when compared to untreated concrete. AT-HARDCON when applied penetrates into the concrete surface and a chemical reaction takes place, producing a byproduct that fills the pores of the concrete. This process leads to a substantially dense concrete surface with enhanced durability. USES: AT-HARDCON is used as a rapid concrete hardener for Roads, Pavement, Industrial Floors, etc. It is also used as a quick setting agent for construction of water storage tanks, roads, floor slabs, where frame work to be removed quickly, maintenance and restorative works. AT-HARDCON can also be used as a waterproofing agent. As a water-proofer, it is used in basements, flats, plastering walls, reservoirs, etc.

    • Setting time of concrete can be accelerated by increasing the dosage
    • It increases plasticity of fresh concrete or mortar
    • It has no long term deleterious effect on concrete
    • AT-HARDCON makes the concrete dense and prevents from chemical attacks
    • AT-HARDCON waterproof & hardens concrete and cement renderings thus serves dual purpose
  • AT-HARDCON is recommended for use wherever hardened, dust-proofed and improved chemical- and abrasion-resistant surface(s) is required
  • AT-HARDCON is ideal for:
  • Interior horizontal concrete surfaces
  • Freshly poured or older / cured concrete
  • Industrial, commercial or warehouse floor slabs
  • Food preparation, storage and distribution centers
  • Convention centers, sports facilities, etc
  • Freezers, cold rooms, walk-in chillers
  • Schools, hospitals, retail outlets, etc

ADVANTAGES:

  • Increases surface density and durability
  • Reduces surface absorption of liquids yet allows moisture vapour transmission
  • Resists black tire marks
  • Reduces absorption rate of oil and grease
  • VOC compliant, water based
  • Neutralizes surface alkali eliminating efflorescence
  • Will not peel, scratch or delaminate
  • Develops satin sheen
  • Naturally slip resistant
  • Dries quickly for minimal downtime
  • Normal life expectancy of twenty years
  • Minimizes maintenance costs and labour

USAGE:

AT-HARDCON when used in the standard proportion of 4 ltr with 100 kg (2 bags) cement, is required in approximately the following quantities:
MASS CONCRETE (AT-HARDCON dosage in liters):

MIX 1 CUBIC MTR OF FINISHED CONCRETE 1 CUBIC YARD OF FINISHED CONCRETE
1 : 2 : 4 12 9
1 : 1 ½ : 3 16 11

RENDERINGS (4 liters of AT-HARDCON diluted with 4 parts of water suffices for):

RENDERING MIX (Aggregate Size ¾ ”) APPROX. SQ. METRES YARDS 12 SUPER
1 : 2 7.52 9
1 : 3 : 4 10.00 12

TOPPINGS (AT-HARDCON diluted with 4 parts of water suffices for):

FLOOR TOPPING MIXED APPROX. SQ. METRES YARDS 12 SUPER THICKNESS (in mm)
2.5 6.70 8 26 (1”)
2.5 4.20 5 39 (1 ½ ”)
1 : 1 ½ : 3 3.35 4 78 (3 ”)

METHOD OF APPLICATION:

  • MASS CONCRETE
    • Mix 4 litres of AT-HARDCON diluted with 4 parts of water for 100 kg or 2 bags of cement to get the required coverage.
  • CEMENT RENDERINGS
    • In Portland Cement renderings AT-HARDCON is used in the proportion of 4 litres to 100 kg (2 bags) of cement.
    • If the sand is dry, dilute AT-HARDCON with 5 parts of water. For thoroughly damp sand dilute AT-HARDCON with 4 parts of water.
  • INTERIOR RENDERINGS
    • A 1:2 mix of cement and clean gritty sand to a total thickness of not less than 19 mm (3/4″) for three-coat work is strongly advised, for proofing pits or basements. The purpose of three-coat work is to minimise the risk of shrinkage crazing.
  • CLEAN-UP
    • Clean equipment with warm, soapy water. Residue or excess material is nontoxic and does not require special disposal procedures.
