    What is Fly Ash

    Fly Ash is a by product of coal based thermal power station generated by the combustion of pulverisedcoal. Fly Ash is a fine, grey, amorphous powder. It is rich in silica & alumina and spherical in shape. The properties of Fly Ash may vary widely, both physically and chemically, depending upon the nature of coal, the efficiency of coal combustion process and the selection process. Therefore, it is important that when considering the use of Fly Ash to look no further than a company with the in depth technical knowledge and support to manufacture and supply a high quality product, that company is Ashtech (India) Pvt. Ltd.

    Our Technology means even better quality

    Ashtech only selects Fly Ash that is highly reactive and has water reducing characteristics. Our Fly Ash is among the first classified and processed material being made available in India.By classifying and processing, we ensure that a large proportion of our Fly Ash is composed of fine particles, which results in a more controlled and consistent product. Our Fly Ash complies with the stringent International codes of practice such as the BS 3892 Part 1,ASTM C 618, BF EN 450 and IS 3812 Grade I. Our customers can therefore be assured of the highest standards of quality, process control and product consistency.

    Characteristics of fly Ash Advantages of fly Ash
    Fine Particle size Better Workability
    Spherical Particle Shape Reduced Permeability
    Low Carbon Content Reduced Heat of Hydration
    Pozzolanic Reaction Improved Pumpability
      Improved Sulphate and Chloride Resistance
      Reduced Risk of Alkali Aggregate Reaction
      Increased Long Term Strength
      Better Concrete Finish
      Reduced Bleeding and Segregation
      Reduced Shrinkage

    We at ASHTECH take special care in understanding the client's needs. Customers have come to count on our expertise and our willingness to work in total co-operation towards maximum & optimum benefit from usage of Fly Ash and allied products.

    Light Weight Blocks (AAC Blocks)

    Aerated Autoclaved Concrete (AAC) blocks are a high quality green building product that offers a unique combination of strength, low weight, thermal insulation, sound absorption , unsurpassed fire resistance and unprecedented build ability. AAC is a steam-cured mix of fly ash, cement, lime, gypsum and aluminium powder. The high-pressure steam-curing in autoclaves achieves a physically and chemically stable product with an average density being approximately one fifth of normal concrete and one fourth of clay brick . AAC is a natural and non-toxic construction material, saves energy and is eco–friendly.No wonder AAC Blocks are termed as the building material innovation of the century.


    Sound Proof
    AAC wall has an excellent Sound Transmission Class (STC) rating of 44 resulting in virtually soundproof interiors.

    Thermal insulation
    Highest thermal rating in the industry ..R30! Thus provides well insulated interiors keeping out warm air in summers and cold air in winters. AAC reduces air conditioning costs by 30%.

    Earthquake Resistant
    Earthquake forces on structure are proportional to the weight of the building, hence AAC shows excellent resistant to the earthquake forces . Regions of high seismic activity like Japan exclusively use AAC. It has been proven to withstand wind load of category 5 tropical storms.

    Cost Saving
    Being light weight, AAC Blocks drastically reduces the dead weight of the building resulting into reduction in steel (up to 25% to 30%) and cement (up to 20% to 25%) requirement in structural cost. Being 8 times the size of clay brick , AAC wall construction involves 1/3rd the joints thus an overall mortar of saving up to 66% and its automatic manufacturing process gives AAC Blocks an exceptional dimensional accuracy & smooth surfaces, eliminating need of three coat plaster on walls and allows for a final 6mm skin coat (Putty/POP).

    Water Barrier
    Its structure does not allow for capillary action making it impervious to water. It's water barrier properties are further enhanced by adding silicon based additives.

    Energy Efficient
    AAC is 100% green building material & is a walling material of a choice in LEED certified buildings (ITC Centre , the highest rated green building has been built using AAC.) AAC is energy & resource efficient in energy in the sense that it uses least amount of energy & material per m3 of product unlike brick manufacturing process which uses precious top layer agricultural soil. AAC uses Fly Ash (upto 70% of its weight) thus providing the most constructive solution to the "Nations Fly Ash utilization program.".

    High Strength
    High pressure steam- curing autoclaving process gives AAC Blocks unmatchable strength to weight ratio, higher then even M 150 concrete, and far exceeds the Indian Building code requirements.

  • Crystal Marbles Download

    Crystal Marble (CM) has unique properties such as soft colour, zero water absorbtion, excellent weather durability, high gloss, maintenance free and none radioactive. CM is the only stone product with absolute acid and alkali resistance.

    CM is highly used in Local and international markets for flooring, wall cladding, counters and all Interiors and Exterior decorations.

    The beauty and durability of the product makes itself a "Unique Selection" as no other stone has this kind of pure whitness and gossy polish.

    CM is also labeled as "GREEN BUILDING MATERIAL" that highlights environmental protection and enjoys a favorable reputation in Domestic and International market.

    Why Crystal Marble?
    CM gets it flawless whiteness by virtue of high quality raw material free from any pigments.
    CM does not use any resins or epoxy based binding material.

    The production process of CM replicates the process of granite formation, at very high temperature & pressure under strict quality control hence it has strength rendering it almost scratch resistant.
    CM is resistant to strong household cleaning agents ulike others artificial stonees.

    Application of Crystal Marble:
    Flooring- Interior and Exterior.
    Wall Cladding, Counter Tops, Kitchen, Bar Counters and Bathroom Decorations etc.
