Other Details

Quality Assured: Ashtech is committed in supplying high quality products. Our Fly Ash conforms to the most stringent international standards and is subjected to strict quality control procedures to ensure that only consistent and reliable material is supplied. Quality assurance certification is available on request. Additional Rates and Handling: Deciding the most suitable Fly Ash content depends on a number of factors including design strength, placing method and durability requirements. Typical addition rates of Fly Ash in concrete range between 25% - 35% by weight of the cementitious content of the mix. For reducing heat of hydration in massive concrete placements the dosage could go up to 55% replacement by weight of cement. To achieve optimum benefits of Fly Ash, proper curing in line with good concrete practice should always be followed. Fly Ash can be handled in terms of batching, mixing and delivery of concrete in exactly the same way as cement using the same equipment. In dry power, it is often recommended that an aeration system be installed to facilitate easy discharge of Fly Ash from the silo. Fly Ash can be used in conjunction with other cement extenders in the mix and is compatible with a wide range of admixtures, often resulting in more cost effective dosages.
