Construction Material

Product Details:

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. It helps in compressive strength, bond strength, and abrasion resistance. Addition of silica fume also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges. Silica fume reduces bleeding significantly because the free water is consumed in wetting of the large surface area of the silica fume and hence the free water left in the mix for bleeding also decreases. Silica fume also blocks the pores in the fresh concrete so water within the concrete is not allowed to come to the surface.

COPPER SLAG

Copper slag is a by-product of copper extraction by smelting. During smelting, impurities become slag which floats on the molten metal. 

Slag that is quenched in water produces angular granules which are disposed of as waste or utilized.
The physico-mechanical characteristics of copper slag suggest that it can be utilized in the cement and concrete industry.  Granulated copper slag exhibits pozzolanic properties, and then, it could be used as a constituent for common Portland cement.
When slowly cooled and milled to be used as fine or coarse aggregate in high-strength concrete, the concrete showed comparable or even superior mechanical properties compared with conventional OPC. Depending of the composition and characteristics of copper slags, they can be used as ballast, abrasive material, fine aggregate in concrete, aggregates in hot mix asphalt pavements, cement raw material, roofing granules, glass, tiles, and so on.

The pH, colour and hemical composition of vermiculite will vary depending on the source from deposits around the world. Vermiculite possesses cation exchange properties, thus it can hold available to the growing plant ammonium, potassium, calcium and magnesium. Vermiculite, when combined with peat or composted pine bark compost, promotes faster root growth and gives quick anchorage to young roots. The mixture helps retain air, plant food and moisture, releasing them as the plant requires them. Vermiculite is very light in weight, easy to handle and easily mixes with soil, peat, composted pine bark, fertilizers, pesticides and herbicides. Its use as a carrier and bulking agent ensures more even distribution in mixing operations.

Concrete treated with a sodium silicate solution helps to significantly reduce porosity in most masonry products such as concrete, stucco, and plasters. A chemical reaction occurs with the excess Ca(OH)2 (portlandite) present in the concrete that permanently binds the silicates with the surface, making them far more durable and water repellent. This treatment generally is applied only after the initial cure has taken place (7 days or so depending on conditions). These coatings are known as silicate mineral paint.
