GUPTA Central Public Works Department, New Delhi CHIEF ENGINEER (CDO) SUPERINTENDING ENGINEER (CDO) (Alternate) BIS Directorate General SHRI J. C.

BHADRA Scientist ‘B’ (As sistant Director), Civil Engg, BIS iii iv Building Construction Practices including Painting, Varnishing and Allied Finishes, CED 13 FOREWORD Users of various Civil Engineering Codes felt the need for explanatory handbooks and other compilations based on Indian Standards. The need was further emphasized in view of the publication of the National Building Code of India in 1970 and its implementation. The Expert Group set up in 1972 by Department of Science and Technology, Government of India carried out in depth studies in various of Civil Engineering and Construction Practices. During the preparation of the Fifth Five Year Plan in 1975, the Group was assigned the task of producing a Science and Technology Plan for research, development and extension work in the sectors of housing and construction technology. One of the items of this plan was the formulation of design handbooks, explanatory handbooks and design aids based on the National Building Code and various Indian Standards and other activities in the promotion of the National Building Code. The Expert Group gave high priority to this item and on the recommendation of the Department of Science and Technology, the Planning Commission approved the following two projects which were assigned to the Bureau of Indian Standards (erstwhile Indian Standards Institution): a) Development programme on code implementation for building and civil engineering construction, and b) Typification for industrial buildings A Special Committee for Implementation of Science and Technology Projects (SCIP) consisting of experts connected with different aspects was set up in 1974 to advise the BIS Directorate General in identifying the Handbooks and for guiding the development of the work. Under the first project, the Committee had identified several subjects for preparing explanatory handbooks/compilations covering appropriate Indian Standards/Codes/Specifications. One of the compilations suggested was the Handbook on Summaries of Indian Standards for Building Materials, SP 21, first published in 1983 for the standards referred in Part 5 of National Building Code of India. Ensuring the quality and effectiveness of building materials used in the construction and storage are as important as the other phases of building activity like planning, designing and constructing the building itself. Therefore, the Handbook gives a brief summary of the contents of Indian Standards on building materials to indicate such aspects as quality requirements, dimensions, range of properties, limitations on use, etc. This, however, does not cover the standards relating to paints and other specifications not of direct concern to buildings. This Handbook assists the professional Engineer/Architect, etc to choose the material for the purpose of their design and estimation. The general format of the summaries is, scope; range of sizes; important requirements regarding physical, mechanical and other properties; reference to appropriate methods of testing and other related material specifications. It may be noted that the Handbook does not form part of any Indian Standard on the subject and does not have the status of an Indian Standard. Wherever, if there is any dispute about the interpretation or opinion expressed in this Handbook, the provisions of the latest version of the Standards only shall apply; the provisions of this Handbook should be considered as only supplementary and informative. As many of the Indian Standards referred in the Handbook have been revised and many new Standards have been formulated since its first publication, it was decided to revise this Handbook. This revised version, while basically retaining the structure of 1983 version, explicitly provides for: v a) The summaries of all the latest available Indian Standards on Building Materials including those formulated after the first publication of Handbook (this takes into account all the standards published till 31 December 2004) b) More user friendly version by suitable rearrangements of standards within the chapter. The Handbook is based on the draft prepared by Shri K. Raghavendran, Former Deputy Director General, Bureau of Indian Standards. The Draft Handbook scrutinized within BIS, was circulated for review to Shri A.K. Sarkar, Former Chairman-cum-Managing Director, National Building Construction Company, Building Materials and Technology Promotion Council, New Delhi, Central Building Research Institute, Roorkee and Central Public Works Department, New Delhi and views expressed by them were taken into consideration while finalizing the Handbook. vi
