Properties of Slag Concretes p2infohouse.org

Figure 15: Effect of slag replacement. Durability. Carbonation. The rate of carbonation of slag cement concrete has been reported to be higher than that of Portland cement concrete, especially at high slag replacement values. In all cases, the rate of carbonation is related directly to the compressive strength of concrete

Using Fly Ash in Concrete precast.org

May 08, 2010 · All precast concrete producers can now use a group of materials called "fly ash" to improve the quality and durability of their products. Fly ash improves concrete''s workability, pumpability, cohesiveness, finish, ultimate strength, and durability as well as solves many problems experienced with concrete today–and all for less cost.
