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. ...
Liquid Penetrant Test on Concrete: Purpose, Procedure, and Applications
Liquid penetrant test, also known as dye penetrant inspection (DPI) or liquid penetrant inspection (LPI), is a non-destructive testing method that is used for detection of different types of cracks in concrete such as fatigue cracks, quench cracks, grinding cracks, overload cracks, ...
Radiographic Evaluation of Concrete
Radiographic evaluation of concrete involves the use of radiographic test on building elements to examine the internal condition of concrete. This test is capable of examining concrete members without causing any damages. It determines the location of reinforcing steels, voids ...
Cold Weather Concreting: Guidance, and Strategies
Cold weather concreting is the process of placement, finishing, curing, and protection of concrete during cold weather, as per ACI 306.1. The cold weather occurs when the average outdoor temperature is below 4.4C (40F) for more than three successive days. ...
Determination of Dry Density of Soil by Water Displacement Method
Water displacement test method is used to determine the dry density of soil. It is suitable for evaluating in-place dry density of cohesive soil due to the nature of specimen required. The soil sample should be trimmed to obtain a ...
Determination of In-situ Soil Dry Density by Sand Replacement Method
The sand replacement test method is used to determine in situ dry density of soil. The procedures, materials, equipment, and specifications of this test is based on the Indian Standard (IS 2720 part 28). This test is of significant importance ...
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 ...
