PROPERTIES AND MIX DESIGNATIONS - MnDOT

The finest materials contribute to the plasticity and cohesiveness of the mix, mainly the cementitious portion of the concrete (cement, fly ash, ground granulated blast furnace slag, and silica fume). The cementitious content, however, is usually fixed by other considerations. Air entrainment greatly improves plasticity and cohesive ness.

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 solved many problems experienced with concrete today–and all for less cost. Fly ash, however, must be used with care.
