ASTM C1602 PDF

It defines sources of water and provides requirements and testing frequencies for qualifying individual or combined water sources. In any case where the requirements of the purchaser differ from these in this specification, the purchaser's specification shall govern. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Published March Box , Farmington Hills, MI No further reproductions authorized. Requirements for Use. Batch water water weighed or metered through the batch plant ,. Water added by truck operator,. Free moisture on the aggregates, and. Water introduced in the form of admixtures when this water increases the water-cementitious materials ratio by more than. Potable water is permitted to be used as mixing water in concrete without testing for conformance with the requirements. When the non-potable water source is.

Testing and Requirements. Testing is permitted to be at a lower frequency, but not less than annually when results from four consecutive tests indicate compliance with Table 1. These records shall be provided to the purchaser on request. Manufacturers that use automated devices shall maintain at the production facility documentation on the procedures and calibration of systems, as needed See Note 1.

TABLE 1. Concrete Performance Requirements for Mixing Water. Test Methods. From early to later. See Annex A1. B Compressive strength results shall be based on at least two standard test specimens made from a composite sample. Test Method. Maximum concentration in combined mixing water, ppm A. Maximum concentration in combined mixing water, ppm B. Chloride as Cl - , ppm. C Sulfate as SO 4 , ppm. Total solids by mass, ppm. B ppm is the abbreviation for parts per million C The requirements for concrete in ACI shall govern when the manufacturer can demonstrate that these limits for mixing water can be exceeded.

For conditions allowing the use of calcium chloride CaCl 2 accelerator as an admixture, the chloride limitation is permitted to be waived by the purchaser. Testing frequency is permitted to be reduced to once every 12 months when the results of two consecutive tests indicate compliance with the requirements of Table 1 See Note 2. Testing frequency is permitted to be reduced to once every three months when the results of 4 consecutive tests indicate compliance with the requirements of Table 1 See Note 3.

N OTE 3—Water density of 1. N OTE 4—Water density exceeding approximately 1. The producer should have a documented process in place to verify the effectiveness of the admixtures and dosages employed.

These requirements shall apply to the combined water at the highest solids. These records shall be provided to the purchaser on request See Note 5.

Therefore, for the purposes of testing for compliance to the requirements of Table 1 and Table 2, it is acceptable to sample, proportion, and combine the individual sourc es of water to produce a test sample that is representative of the actual combined mixing water used in production. Mandatory Information. To comply with the performance requirements in Table 1, comparison between two concrete mixtures is required: one as a control batch using a potable water source, and a second as a test batch using the water source s proposed for use.

The following shall apply:. The air-entraining admixture shall be adjusted to produce the target air content with a tolerance of 6 1. The dosage of water reducing admixture shall be the same in both batches. No other set controlling admixtures are permitted. Mixing water content of the test batch shall not be less than the mixing water content of the control batch.

Mixture proportions shall be made available upon request. Nonmandatory Information. Combined Water Den-. Testing Frequency. Density, C Table 1. Table 2. Non-Potable A. Daily 5. Production A.
