New Guide for Evaluating the Comparative pH of Reagent Water Placed on a Concrete Slab Surface
1. Scope
1.1 This guide discusses procedures that may be used for evaluating the comparative change in pH of reagent water placed on the surface of a properly prepared concrete slab surface. 1.2 This guide is intended to be used in conjunction with the flat surface electrode pH meter manufacturers calibration procedures, operation instructions, and interpretive data where available. 1.3 This guide is intended to be used in conjunction with the pH paper manufacturers instructions, product shelf life, and interpretive data where available. 1.4 This standard does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Some specific hazards statements are given in Section 9 on Hazards. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Keywords
1.1 alkali; carbonation, pH, reagent water; substrate
Rationale
WK Item 69831 was withdrawn due to one or more persuasive negatives. Previous methods to evaluate concrete slab surface pH had no requirement to test the pH of the reagent water (distilled or deionized) before using that water to evaluate the concrete slab surface pH. The proposed standard addresses this.
The title and scope are in draft form and are under development within this ASTM Committee.
