Aci 31814 Design Examples2000 Psi Concrete Mix Ratio

concrete durability requirements based on aci-318-19,a specific exposure class of concrete structure may govern several aspects of concrete, for instance, mix proportion, strength, addition of mineral and chemical admixture. the durability requirement of concrete necessitates low water to cement ratio and addition of cementitious materials, for instance, silica fume, fly ash, and ground granulated blast furnace slag to decrease water penetration.aci mix design example – pavement interactive,aci mix design example. a concrete mix is to be designed for use in a 250 mm (10 inch) thick jpcp pavement. the desired properties are: slump = 25 mm (1.0 inch) average 28-day flexural strength of at least 4.5 mpa (650 psi) coarse aggregate: nominal maximum size = 37.5 mm (1.5 inch), dry-rodded weight = 1600 kg/m 3 (100 lb/ft 3 ), specific.

    but what happens if that 3000 psi design mix also has a maximum 0.40 w/cm ratio and produces an average strength of 6500 psi? can we still use the “3000 psi” design mix? while it isn’t really a gap, another concern is the fact that there are numerous discrepancies between how aci 318, the code, and aci 301, specification for concrete, address strength overdesign.
