Fly ash supplied by Ash Resources is a key component in the Department of Water Affairs’ new De Hoop Dam in Limpopo.Ash Resources, South Africa’s leading supplier of fly ash, has been awarded associate membership of the South African National Committee on Large Dams (SANCOLD).

Fly ash has become virtually a standard ingredient of concrete mixes for water-retaining structures all over the world. It has the particular benefit of keeping temperature build-up in mass concrete pours to a minimum and helps produce durable, impermeable concrete with good off-shutter finishes.
