Fly ash additive
BATIMIX Fly Ash DG3-P is a powder fly ash pozzolanic additive used in wet and dry-mix shotcrete applications to enhance strength and durability and reduce the permeability of hardened concrete.
BATIMIX Fly Ash DG3-P are ultra-fine particles that significantly improve the particle packing of shotcrete mixes as they physically fill voids in the cement paste. This leads to a more densified shotcrete skeleton with a reduced level of bleeding. On the other hand, this product reacts chemically with the calcium hydroxide present in the cement paste, yielding a calcium silicate hydrate gel that significantly enhances strength, water/chloride impermeability, and durability. Applications incorporating this product include all types of high strength and specialty shotcrete and repair applications.
Shotcrete prepared with BATIMIX Fly Ash DG3-P are characterized by the following:
In the plastic state:
In the hardened state:
15% to 25% of the cement weight
Batimix Fly Ash DG3-P is not a hazardous material. However, it should not be swallowed or come into contact with eyes. Suitable goggles should be worn.
Fly ash is a byproduct of burning coal in power plants, and it can contain small amounts of heavy metals. Therefore, proper handling and disposal of fly ash are important to ensure public safety and environmental protection.
The Occupational Safety and Health Administration (OSHA) has set regulations for the handling and storage of fly ash to protect workers from potential health hazards. These regulations include measures such as providing personal protective equipment, establishing proper ventilation, and minimizing worker exposure to fly ash dust.
In addition, the Environmental Protection Agency (EPA) has established guidelines for the disposal of fly ash to prevent environmental contamination.
Overall, with proper handling, storage, and disposal, fly ash can be safely managed and its potential risks minimized.
