The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminology and conventions are, however, not identical to those used in Indian Standards.. Attention is particularly drawn to the following: a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'. b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker. The technical committee responsible for the preparation of this standard has reviewed the provisions of the foilowing International Standard referred in this adopted standard and has decided that it is acceptable for use in conjunction with this standard: International Standard Title ISO 11375 :1998 Building construction machinery and equipment—Terms and definitions For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis shall be rounded off in accordance with IS 2:1960 'Rules for rounding off numerical values {revised}'. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. IS/ISO 21573-1 : 2006 Indian Standard BUILDING CONSTRUCTION MACHINERY AND EQUIPMENT — CONCRETE PUMPS PART 1 TERMINOLOGY AND COMMERCIAL SPECIFICATIONS 1 Scope This part of ISO 21573 establishes terminology and commercial-literature specifications for concrete pumps which are used on building sites for concrete-mix delivery. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 11375:1998, Building construction machinery and equipment — Terms and definitions 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 11375 and the following apply. 3.1 piston-type concrete pump pump in which a piston is used to impart energy to the concrete mix, with the intent of transporting the mix to and through the conveying pipe and/or hose See Figure A. 1. 3.2 rotary-type concrete pump pump in which a peristaltic action is used to impart energy to the concrete mix with the intent of transporting the mix to and through the conveying pipe and/or hose See Figures A.6, A.7, A.8 and A.9. 3.3 stationary-type concrete pump skid, rail or wheeled-chassis mounted concrete pump intended for long-term operation on one building site See Figure A. 13. 1 IS/ISO 21573-1 : 2006 3.4 piston-type concrete-pump's valve system system composed of cut-off valves successively locking and opening concrete-mix flow from the hopper to the concrete cylinder and from the latter to the conveying pipe See Figures A.2, A.3, A.4 and A.5. NOTE The operation of the valves is synchronised so that, when the concrete-mix flow from the hopper to the concrete cylinder is opened, the flow to the conveying pipe is closed. Various types of valve systems (see Table 1) are identified. 3.5 distributing boom folded boom with fixed concrete-mix conveying pipe of which the role is to deliver concrete mix to work areas within its reach See Figure A.14. NOTE The boom has the possibility of folding in the vertical plane and slewing around the vertical axis. Typically, a rubber hose is fixed to the end of the conveying pipe, to facilitate concrete-mix distribution. 3.6 maximum applicable aggregate size largest size of aggregate that can be consistently delivered through the concrete pump without blockage, including through any conveying pipe that is normally supplied on the finished product 3.7 minimum applicable slump minimum value of slump applicable for conveying by concrete pump 3.8 maximum theoretical pumping capacity theoretical delivery volume which is obtained at the maximum strokes/revolutions per minute of concrete pump NOTE The actual delivery volume is obtained by calculating the product of the volumetric efficiency and the theoretical delivery volume of the concrete pump. Using concrete of slump value 18 cm to 21 cm, the volumetric efficiency is about 90%. 2 IS/ISO 21573-1 : 2006 4 Classification of the concrete pumps In general terms, concrete pumps are typically classified by the following four main characteristics (see Table 1): — type of pumping unit; — mode or frequency of transportation; — form of conveying; — concrete-mix delivery with assistance.
