How to perform ultrasonic pulse velocity test as per Indian Standard 13311- Part-1 : 1992 and calculation

 Introduction:- The underlying principle of assessing the quality of concrete is that, for ‘Good’ concrete in terms of density, homogeneity velocities are more than that of ‘weak’ concrete containing imperfection/voids/porosity etc. In order to examine and evaluate the conditions of in-situ concrete the structural investigation shall primarily require assessment of homogeneity of concrete in terms …

Non Destructive testing by Schmidt Hammer as per provisions of IS: 13311 – 1992

Introduction (Schmidt Hammer): This is a simple, handy tool, which can be used to provide a convenient and rapid indication of the compressive strength of concrete. It consists of a spring controlled mass that slides on a plunger within a tubular housing. The schematic diagram showing various parts of a rebound hammer is given as …

How to test compressive strength of concrete by cube test method

 Importance Define Compressive Strength of Concrete: Compressive strength of concrete is defined load carrying capacity of concrete in compression. This parameter denotes the quality of concrete as concrete strength is main in compression only. Compressive strength is main criteria to design a structure using concrete in it. Compressive strength determined from lab test is also …
