DESIGN CRITERIA:1. Concrete shall be composed of Portland Cement, fine aggregate, coarseaggregate, admixtures and water, as specified.2. ACI 211.1 shall be the basis for selecting the proportions for concrete made withaggregates of normal density and of workability suitable for usual cast-in-placestructures.3. The design of the concrete shall be consistent with the minimum requirements ofstrength and proportions stated herein and in accordance with ACI Standard211.1 "Recommended Practice for Selecting Proportions of Concrete," subject tomaximum water cement ratio, minimum cement content and minimum strengthsspecified.4. The workability of any mix shall be as required for the specific placingconditions and the method of placement. The concrete shall have the ability tobe worked readily into corners and around reinforcing steel without thesegregation of materials or the collection of free water on the surface.Compliance with specified slump limitations shall not necessarily designate asatisfactory mix.5. In no case shall the amount of coarse material produce harshness in placing orhoneycombing in the structure, when forms are removed.B. CONCRETE CLASSIFICATIONS:(see following page for chart)03300-1
