Normal-Weight Concrete Mixtures: Proportion by either laboratory trial batch or field test data methods according to ACI 211.1, with materials to be used on Project, to provide normal-weight concrete with the following properties:
A. Compressive Strength (28 Days): 5000 psi minimum.
B. Maximum Water-Cementitious Materials Ratio: 0.45.
Water Absorption: 6 percent by weight or 14 percent by volume, tested according to PCI MNL 116.
Add air-entraining admixture at manufacturer's prescribed rate to result in concrete at point of placement having an air content complying with PCI MNL 116.
When included in design mixtures, add other admixtures to concrete mixtures according to manufacturer's written instructions.
Concrete Mix Adjustments: Concrete mix design adjustments may be proposed if characteristics of materials, Project conditions, weather, test results, or other circumstances warrant.
