Post-Concrete Inspection and Testing: Purpose, and Applications
Post concrete inspection of concrete structures is essential to check for any damage or defects that may require repair. Immediately after stripping the formwork, all concrete members casted are carefully inspected and any defective work or small defects either removed ...
How to Measure Reinforcement Corrosion in Concrete Structures?
Measurement of steel reinforcement corrosion in concrete is essential to analyze the strength and durability of a structure. Not only does the steel corrosion reduce the life span of the structure but also increases the cost for inspection and maintenance ...
Profometer Test on Concrete Structures: Purpose and Applications
Profometer test is a non-destructive testing technique used to detect location and size of reinforcements and concrete cover quickly and accurately. A small, portable, and handy instrument which is known as profometer or rebar locator, is used in this test. ...
Double Shear Test on Mild Steel
Double shear test is used to determine the shear strength (ultimate shear stress) of the mild steel specimen. Universal testing machine (UTM) is used for performing double shear test. There are two types of UTM namely: screw type and hydraulic ...
Bulk Density and Void Percentage Test for Aggregates
The bulk density and void percentage of aggregate can be evaluated using standard test methods of applicable codes such as ASTM C 29/C29M-17a, IS: 2386 (Part 3) – 1963, or BS 812-2:1995. The procedure provided in this article is based ...
Variable Head Permeability Test of Soil- Purpose, and Procedures
Variable head permeability test is one of several techniques by which the permeability of soil is determined. It is used to evaluate the permeability of fairly less previous soil. Permeability is the measure of the ability of soil to allow ...
