Description

Testing of Construction Materials provides thorough understanding of the testing techniques in the subject. A brief theory is included with each experiment to familiarize the students with the basic principles and objectives. Photographs and figures of the experimental setup have been studied. The procedure, methods and relevant tables are based upon Indian standard specifications. Sample data along with the interpretation, calculations, relevant graphs and results are included for the students to understand various steps involved in testing techniques. A sufficient number of viva-voce questions are given at the end of each experiment.
