This specification covers mixing water used in the production of hydraulic cement concrete. It defines sources of water and provides requirements and testing frequencies for qualifying individual or combined water sources. Mixing water shall consist of: batch water, ice, water added by truck operator, free moisture on the aggregates, and water introduced in the form of admixtures. Potable and non-potable water is permitted to be used as mixing water in concrete. The following are concrete performance requirements for mixing water: compressive strength and time of set. Density of water shall be tested or monitored with a hydrometer. Optional chemical limits for combined mixing water are given for: chloride, sulfate, alkalis, and total solids.
WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM C1602 for Mixing Water Used in the Production of Hydraulic Cement Concrete.
