    Ground Granulated Blast Furnace Slag ( GGBS)

    Approx Price: Rs 12.5 / Kilogram 
    Minimum Order Quantity: 100 Kilogram

    We are leading manufacturers, exporters & suppliers of Ground granulated blast-furnace slag ( GGBS )

    GGBS is used to make durable concrete structures in combination with ordinary portland cement and/or other pozzolanic materials. GGBS has been widely used in Europe, and increasingly in the United States and in Asia (particularly in Japan and Singapore) for its superiority in concrete durability, extending the lifespan of buildings from fifty years to a hundred years.[2]

    Two major uses of GGBS are in the production of quality-improved slag cement, namely Portland Blastfurnace cement (PBFC) and high-slag blast-furnace cement (HSBFC), with GGBS content ranging typically from 30 to 70%; and in the production of ready-mixed or site-batched durable concrete.

    Concrete made with GGBS cement sets more slowly than concrete made with ordinary Portland cement, depending on the amount of GGBS in the cementitious material, but also continues to gain strength over a longer period in production conditions. This results in lower heat of hydration and lower temperature rises, and makes avoiding cold joints easier, but may also affect construction schedules where quick setting is required.

    Use of GGBS significantly reduces the risk of damages caused by alkali–silica reaction (ASR), provides higher resistance to chloride ingress — reducing the risk of reinforcement corrosion — and provides higher resistance to attacks by sulfate and other chemicals.

    MICROSILICA ( GREY ) ( SILICA FUME ) ( FERRO SILICON BASED )

    Microsilica ( Grey ) is a mineral admixture composed of very fine solid glassy spheres of silicon d i oxide (SiO2). Each particles are less than 1 micron in diameter, generally 50 to 100 times finer than average cement or fly ash particles. Frequently called condensed silica fume, microsilica is a by- product of the industrial manufacture of ferro silicon and metallic silicon in high-temperature electric arc furnaces. The ferrosilicon or silicon product is draw n off as a liquid from the bottom of the furnace. Vaporizing from the 2000-degree-C furnace bed is oxidized, and as it cools condenses into particles which are trapped in huge cloth bags. Processing the condensed fume to remove impurities and control particle size yields microsilica.

    Calcium Chloride

    Calcium Chloride
    ( Anhydrous )
    For Concrete application

    Investigations have shown that a two per cent addition of calcium chloride has equal cure strength at 50F as plain concrete has at 70F. Regardless of the temperature or cement type, concrete mixes containing calcium chloride will always have a faster cure rate than plain concrete.

    The beneficial effects of calcium chloride will be even more pronounced at lower temperatures. The accelerated cure rate measured as final concrete set time can be reduced by two-thirds when two per cent calcium chloride is added - two hours compared to six hours for plain concrete.
    calcium chloride can accelerate cement hydration reducing its set time.

    That means:


    high initial strength
    reduced final set time
    reduced bleeding
    improved workability
    fast form work turnaround
    greater cost effectiveness
    beneficial when used with fly ash or Microsilica

    *Effect of Calcium Chloride on Portland Cements and Concretes.

    COLD WEATHER CONSTRUCTION

    Low temperatures slow concrete hydration. That is why an accelerator is needed to obtain high initial strength. Calcium Chloride accelerates hydration and gives concrete the strength and durability to meet specification requirements at lower temperatures.

    Silica Ash
    ( Rice Husk Ash )

    RHA is a good super-pozzolans . RHA can be used in a big way to make special concrete mixes There is a growing demand for fine amorphous silica in the production of special cement and concrete mixes ,high performance concrete ,high strength, low permeability concrete, for use in bridges, marine environments , nuclear power plants etc.

    USE OF RICE HUSK ASH
    For Strength :
    Adding RHA to the concrete mix even in low replacement will dramatically enhance the workability , strength and impermeability of concrete mixes , while making the concrete durable to chemical attacks , abrasion and reinforcement corrosion , increasing the compressive strength by 10% - 20 % .

    For water proofing :
    RHA has excellent water resistance ( impermeability ) properties and is used in waterproofing compounds to give amazing results. it reduces the water penetration by as much as 60 % .

    For Better Concrete in Marine environment:
    Adding RHA to concrete and paints helps to reduce the chloride ion penetration by as much as 50 % into the structure , thus improving life of the building.

    For Lower heat of Hydration :

    Adding RHA to concrete lowers the heat of hydration by as much as 30 % and prevents formation of cracks during casting .
    RHA acts as a very good insulator . RHA is also used for insulation of molten metal in tundish and ladle in slab caster .
    The temperature of molten metal in the ladle is around 1400 degrees centigrade and above . When this metal flows from ladle to tundish , the temperature drops to around 1250 degrees . This reduction in temperature leads to choking and causes breakdown in the slab caster.
    When this RHA is spread as a coating over the molten metal in the tundish and in ladle , it acts as a very good insulator and the temperature is maintained and does not cool down quickly , hence reducing the breakdown time of the casting.
    Rice Husk is burnt in controlled temperatures which is below 700 degrees centigrade . This ash generated is amorphous in nature . The transformation of this amorphous state to crystalline state takes place if the ash is exposed to high temperatures of above 850 degrees centigrade .

    Green Concrete : Green Concrete as the name suggests is eco friendly and saves the environment by using waste products generated by industries in various forms like rice husk ash ,micro silicaetc. to make resource-saving concrete structures .Use of green concrete helps in saving energy,emissions, waste water Green concrete is very often also cheap to produce as it uses waste products directly as a partial substitute for cement,thus saving energy consumption in production of per unit of cement . Over and above all green concrete has greater strength and durability than the normal concrete.
    High Performance Concrete : Also known as HPC , the name given to mixtures with high workability and very high early strengthsand long term durability .

    • High performance, high strength, and lightweight concrete
    • Precast and poured-mold concrete
    • Fibercement and ferrocement products
    • Glass fiber reinforced concrete
    • Countertops, art sculptures
    • Mortar and stucco

    It is fired (calcined) under carefully controlled conditions to create an amorphous aluminosilicate that is reactive in concrete. Like other pozzolans (fly ash and silica fume are two common pozzolans), metakaolin reacts with the calcium hydroxide (lime) byproducts produced during cement hydration.

    Calcium hydroxide accounts for up to 25% of the hydrated Portland cement, and calcium hydroxide does not contribute to the concrete’s strength or durability. Metakaolin combines with the calcium hydroxide to produce additional cementing compounds, the material responsible for holding concrete together. Less calcium hydroxide and more cementing compounds means stronger concrete.

    It is very fine and highly reactive, gives fresh concrete a creamy, non sticky texture that makes finishing easier.

    Our experience has shown that optimal performance is achieved by replacing 10% to 15% of the cement with metakaolin. While it is possible to use less, the benefits are not fully realized until at least 10% metakaolin is used. The advantage of replacing some of the cement with metakaolin, rather than simply adding metakaolin to the mix, is that any existing color formulas or mix designs won’t change, or will only very slightly change. This is because the dosage of pigments and superplasticizers are based on the cement content in the concrete. Of course, it is ok to simply add metakaolin to an existing mix, but it’s important to realize that the total equivalent cement content will increase. Be aware that this will affect not only the pigment and admixture dosages but also the water to cement ratio, a critical factor in mix design.

    How well metakaolin behaves depends on your mix design and, more critically, on how much mix water is used. Keep in mind that any admixture must be used wisely. All the other factors (good mix design, proper reinforcing, etc) must also be properly designed and accounted for in order to take advantage of the benefits metakaolin can give you.

    For example, making a very high compressive strength concrete is pointless if the reinforcing is inadequate.

    Metakaolin is compatible with most concrete admixtures, such as superplasticizers, retarders, accelerators, etc. If questions arise as to compatibility with any admixtures you use in your mix, consult with the admixture manufacturer for guidance.
