PROPERTIES AND MIX DESIGNATIONS

Cementitious materials include portland cement, sla g, silica fume, fly ash, and any other material having cementitious properties as approved by the Engineer. While strength is always an indicator of quality concrete, it does not necessarily correlate to durable concrete. A low w/c ratio is a good indicator of durable concrete.
