    Daffcon Integral Waterproofing Compound

    It is specially formulated unique brown coloured liquid integral water proofing compound for concrete, mortar and plaster based special selective polymers, surface active agents and additives for ensuring better waterproofing.


    Daffcon Integral Waterproofing Compound is generally dosed @ 200 ml per 50 kg of cement. The dosage can also be varied from 0.2 to 0.6% by weight of cement depending on requirement.

    Ground Granulated Blast furnace Slag (GGBS)

    Ground Granulated Blast furnace Slag (GGBS) [1] is a byproduct from the blast furnaces used to make iron. These operate at a temperature of about 1500 degrees centigrade and are fed with a carefully controlled mixture of iron ore, coke and limestone. The iron ore is reduced to iron and the remaining materials from a slag that floats on top of the iron. This slag is periodically tapped off as a molten liquid and if it is to be used for the manufacture of GGBS it has to be rapidly quenched in large volumes of water. The quenching optimizes the cementitious properties and produces granules similar to coarse sand. This „granulated‟ slag is then dried and ground to a fine powder which is called GGBFS (Ground granulated blast furnace slag).

    Uses of GGBS

    The major use of GGBS is in ready mixed concrete, and it is utilized in a third of all UK [2] „ready-mix‟ deliveries. Specifiers are well aware of the technical benefits, which GGBS imparts to concrete, including:

    • Better workability, making placing and compaction easier.
    • Lower early age temperature rise, reducing the risk of thermal cracking in large pours.
    • Elimination of the risk of damaging internal reactions such as ASR
    • High resistance to chloride ingress, reducing the risk of reinforcement corrosion  High resistance to attack by sulphate and other chemicals  Considerable sustainability benefits

    Daffcon PB Curing Compound

    DAFFCON PB a white pigment which at recommended coverage rates gives a daylight reflectance value of 60-80%.This permits a high curing efficiency to be maintained even in conditions of intense ambient light.

    DAFFCON PB is solvent free, suitable for spray application to freshly poured concrete, the resultant film retains sufficient moisture in the concrete to ensure full hydration of the cement;

    essential for optimum strength development. Membrane cured concrete is typically harder and exhibits a dust free surface with a reduced incidence of drying shrinkage cracks.


    All concrete and plaster surfaces which requires curing

    • Towers, Bridge decks, Highways, Canals, Dams
    • Rams &walls.
    • Dry shake hardened floors used over, Hospitals & Industrials.
    • Runways retaining walls.
    • RCC repaired sections.


    Meets the requirement of ASTM: C 309

    • VOC free - Water based product. No objectionable fumes.
    • Ease of application - Quickly and easily applied by brush or spray application
    • Curing - Forms an efficient barrier of moisture for optimum curing of concrete.
    • Water & time saving - Eliminates the requirement of water in traditional repeatating concrete curing method
    • Cracking - Keeps concrete cool by reflecting light and heat and minimizes the chance of surface cracking
    • Bonding - Breaks down by natural weathering to allow subsequent applications over the cured concrete without affecting bonding.
    • Suitability - Suitable for interior and exterior application.


    DAFFCON PB Curing Compound should be applied uniformly at the proper coverage rate by brush or spray on the fresh concrete after the surface has become free from bleeding water and final toweling is over. In-situ concrete should be coated with DAFFCON PB Curing Compound as soon as the shuttering is removed.


    Bauxite is a rock formed from a reddish clay material called laterite soil and is most commonly found in tropical or subtropical regions. Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide. Bauxite ore is the world's primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. Bauxite is very rich in iron and aluminium hence components of the bauxite residue are valuable additions in the production of both Portland Cement and 'special' cement clinkers; and secondly it has been shown at a laboratory scale by several research groups that bauxite residue may successfully replace clinker in blended.

    Chemical Composition


    Laterite can be considered as polymetallic ore as it is not only the essential repository for aluminium, but also a source of iron, manganese, cobalt, nickel and chromium. Furthermore, it is the home for several trace elements like gallium and vanadium which can be extracted as by- products Laterite has been acclaimed to be used as an additive in cement making going by its chemical components. Laterite is used in the production of cement due to the fact that it lowers the temperature of the clinker, supplements deficient aluminous and iron contents that are required in the process of cement making.
