double punch test for tensile strength of concrete wikipedia
Determination of friction angle of soil using double
determination of the tensile strength of concrete, sand, stone or soil The punch test is likely to be one of the accurate procedures in this regard In this test, generally compressive load is used to determine the tensile strength The double-punch test is an indirect tensile test originally proposed by Chen (19701975, ) aimed...
Exp 9 Splitting Tensile Strength
Nov 09, 2015· This test method is used for the determination of splitting tensile strength of cylindrical concrete specimenSplitting tensile strength is helpful for the following purposes; Splitting tensile strength is generally greater than the direct tensile strength and lower than the flexural strength (modulus of rupture)...
Ultimate tensile strength
Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength, or Ftu within equations, is the capacity of a material or structure to withstand loads tending to elongate, as opposed to compressive strength, which withstands loads tending to reduce size...

Shear Test
Purpose of shear testing: The most common use of a shear test is to determine the shear strength, which is the maximum shear stress that the material can withstand before failure occurs, of a material This is a very important design characteristic of many types of fasteners such as bolts and screws...

Use of Double Punch Test to Evaluate the ,
The double punch test (DPT) was originally developed, based on the plasticity theory of concrete, to determine the tensile strength of plain concrete but has rarely been used since the 1980s This test method can be carried out by using conventional compression test machines with small capacity and simple test setup...
Tensile Test on Concrete
It should be noted that both of these methods give the higher value of tensile strength than the uniaxial tensile strength Split-Cylinder Test It is the standard test, to determine the tensile strength of concrete in an indirect way This test could be performed in accordance with IS : 5816-1970...
FURTHER STUDIES OF DOUBLE
test for concrete, the double-punch test has been developed [lJ Preliminary work has been conducted and has resulted in the determination of a standard procedure for the test [2J The purpose of the work represented here was to further investigate experimentally the results of varying several parameters, including the rate of stressing during...
Properties of concrete
Strength gain depends on the type of mixture, its constituents, the use of standard curing, proper testing by certified technicians, and care of cylinders in transport For practical immediate considerations, it is incumbent to accurately test the fundamental properties of concrete in its fresh, plastic state...
Universal testing machine
A universal testing machine (UTM), also known as a universal tester, materials testing machine or materials test frame, is used to test the tensile strength and compressive strength of materialsAn earlier name for a tensile testing machine is a tensometerThe "universal" part of the name reflects that it can perform many standard tensile and compression tests on materials, components, and ....
