    Nano silica
    in the construction industry, extensive research is going on to improve the performance of various building materials and development of durable and sustainable concrete. Among all the nano-materials, nano-silica is the most widely used material in the cement and concrete to improve the performance because of its pozzolanic reactivity besides the pore-filling effect.
    concrete strength is influenced by lots of factors like concrete ingredients, age, ratio of water to cement materials, etc. Nano-silica incorporation into concrete resulted in higher compressive strength than that of normal concrete to a considerable level.
    for nano-silica blended concretes up to maximum limit of 2% with average particle size of 15 and 80 nm. Same results were obtained for split tensile and flexural strength.

    Sodium Hydroxide

    Sodium hydroxide (NaOH) is an inorganic compound. It is a white solid and highly caustic metallic base and alkali salt of sodium which is available in pellets, flakes, granules, and as prepared solutions at a number of different concentrations. Sodium hydroxide forms an approximately 50% (by weight) saturated solution with water.

    Sodium hydroxide is soluble in water, ethanol, and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air.

    Sodium hydroxide is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps, detergents and as a drain cleaner. It is also used in concrete in the construction industry.

    SODIUM SILICATE ( LIQUID )

    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.

    FOUNDRY SAND

    Concrete is a mixture comprised of cement (10-15 percent), coarse and fine aggregates (60-75 percent) and water (15-20 percent) by volume.   Foundry sand can be used as a fine aggregate substitute in concrete.  Fine aggregates are generally 3/8 inch or smaller, while coarse aggregates are 3/8 to 2 inches in diameter. 

    Foundry sand meets two of the critical requirements for concrete aggregates:  it is uniformly graded, and is strong, hard, and durable.
