Transverse Strength Test on Roofing Tiles Based on ASTM C 1167 and IS
The transverse strength test of roofing tile is commonly carried out based on the specifications of applicable standards such as ASTM 1167-11 and IS 13801. It involves wet or dry method test and conducted in the lab to estimate breaking ...
Water Absorption Test on Roofing Tiles
Water absorption test is the measurement of moisture quantity that roofing tile may absorb. If water absorption is too high, the tile may suffer from cracking which is not desirable. So, this test reflects the suitability of the tile for ...
Penetration Resistance Test on Hardened Concrete – Purpose and Application
Penetration resistance tests on concrete offers a means of determining relative strengths of concrete in the same structure or different structures.
Universal Testing Machine – Components and Functions
A Universal testing machine (UTM) is used to test the mechanical properties (tension, compression etc.) of a given test specimen by exerting tensile, compressive or transverse stresses. The machine has been named so because of the wide range of tests ...
Strut Test to Determine Euler’s Buckling Load of Strut
Strut test is used to determine the Euler’s buckling load of the strut. Struts are long, slender columns that fail by buckling some time before the yield stress in compression is reached. The Euler’s buckling load is a critical load ...
Test to Determine Modulus of Elasticity of Concrete
Modulus of elasticity of concrete is defined as the ratio of stress applied on the concrete to the respective strain caused. The accurate value of modulus of elasticity of concrete can be determined by conducting a laboratory test called compression ...
Hydraulic Coefficients of an Orifice
The laboratory experiment procedure to determine hydraulic coefficients of an orifice is explained in this article. The coefficient of contraction, the coefficient of velocity and coefficient of discharge are hydraulic coefficients of an orifice. Theory When flow takes place through ...
