Standard Specification for Mixing Rooms, Moist Cabinets, Moist Rooms, and Water Storage Tanks Used in the Testing of Hydraulic Cements and Concretes
ABSTRACT
This specification includes the requirements for mixing rooms where paste and mortar specimens are prepared and for moist cabinets, moist rooms, and water storage tanks where paste, mortar, and concrete specimens are stored; intended for use in the testing of hydraulic cements and concretes. The system shall be equipped with a temperature recorder and a reference temperature measuring device that are to be placed practically near to each other. The air and mixing water temperatures and the relative humidity in the cement mixing room shall be maintained at specific values. Moist cabinets and moist rooms shall be constructed of durable materials with tight-fitting doors or windows for all openings. Air in moist cabinet or moist room shall be saturated with moisture in order to provide specified storage conditions and air temperature shall be controlled with provisions made for heating, cooling, or both. The specified relative humidity in these systems shall be maintained by the use of one or more fog sprays, water sprays, or curtains of water on the inner walls. Water storage tanks shall be constructed of non-corroding materials with provisions for automatic control of water temperature. The water in a storage tank shall be saturated with calcium hydroxide to prevent leaching.
SCOPE
1.1 This specification includes requirements for mixing rooms where paste and mortar specimens are prepared; and for moist cabinets, moist rooms, and water storage tanks where paste, mortar, and concrete specimens are stored.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. Values in SI units shall be obtained by measurement in SI units or by appropriate conversion, using the Rules for Conversion and rounding given in Standard IEEE/ASTM SI 10, of measurements made in other units.
1.3 This standard does not purport to address all of 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.
