Ground Granulated Blast Furnace Slag ( GGBS )

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. 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.

Grey Microsilica ( Ferro Silicon Base )

Our organization is established as one of the leading manufacturers, suppliers, wholesalers and exporters of quality assured Grey Microsilica ( Ferro Silicon Base ).We export our products all over the world. Product Details: State Powdered Packaging Type Bags MICROSILICA ( GREY ) ( SILICA FUME ) ( FERRO SILICON BASED ) Micro silica powder for high strength concrete 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.

Metakaolin

With the help and support of our professionals, we have been able to manufacture, wholesale and export best quality Metakaolin Powder ( POZZOFILZ ). It is calcinated by the professionals, under the controlled conditions for creating an amorphous aluminosilicate. When mixed with the concrete, it enhances the workability and strength of concrete. It also provides concrete a non sticky texture that makes finishing easier. Application:- High performance, high strength, and lightweight concrete Precast and poured-mold concrete Fiber cement and ferrocement products Glass fiber reinforced concrete Countertops, art sculptures Feature: Purity Longer shelf life Correctly formulated Accurate composition Aggregate Concrete Concrete Admixture Cement admixture Uses :- 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.
