Fly Ash Precast Concrete Parts Precast concrete parts are supporting construction elements. This leads to high demands on the strength and durability of the concrete. The use of coal fly ash according to DIN EN 450 in combination with other carefully selected concrete additives allows the production of concretes that meet these requirements for the production of precast parts. On account of its pozzolanic effect, fly ash can replace a proportion of the cement in the concrete mixture. Its spherical grain shape helps reduce the internal friction of the concrete and thus improves its compactibility.
