The rules of this Code constitute requirements for the design, materials, manufacture, examination, inspection, pressure testing and certification of pumps and valves for use in the nuclear energy system of water cooled commercial nuclear power plants. A nuclear energy system is that part of...
This document specifies the procedure and requirements for examining the technical commercial specifications of factory new piston-type concrete pump and rotary-type concrete pump as defined in ISO 21573-1. It applies to mobile concrete pumps (with or...
This Standard applies to the design, manufacture, installation, operation, responsibilities, inspection, testing, and maintenance of concrete pumps, placing booms, and delivery systems. Note: See Figures 1 to 6 for illustrations of the equipment covered by this Standard. This Standard...
This guide for concrete pumping discusses equipment use, proper mixtures for good pumpability, and field practices. References cited provide more detailed information on specific subjects. This guide does not address shotcreting or pumping of nonstructural insulating or...
This guide addresses methods for selecting proportions specific to hydraulic-cement concrete to be placed by pumping. The primary focus of this document is to discuss the principles of mixture proportioning for normalweight and lightweight concrete. Any specific information...
This part of ISO 21573 establishes terminology and commercial-literatur
5.1 Test Methods A and B provide percent void content determined under standardized conditions which depend on the particle shape and texture of a fine aggregate. An increase in void content by these procedures indicates greater angularity, less sphericity, rougher surface texture, or combinations...
3.1 This test method covers the determination of the air content of freshly mixed concrete. The test determines the air content of freshly mixed concrete exclusive of any air that may exist inside voids within aggregate particles. For this reason, it is applicable to concrete...
1.1 This specification covers asphalt suitable for undersealing portland-cement concrete and overlaid concrete pavements by pumping hot asphalt under the slabs. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values...
