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. ...
Compounds in Cement and Their Influence on Concrete Strength
Compounds in cement mainly are tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium alumino ferrite. Not only do these compounds control most of cement properties but also reacts with water to produce new materials (cement hydration) and consequently responsible for ...
Tests on Metallic Sheathing Ducts – Workability, Transverse Load, Tensile Load, and Water Loss Test
The sheathing ducts are used in Pre and Post tension of concrete members to create a void in the concrete, through which the cables/tendons are inserted and remain free to stretch during stressing operation. The sheathing ducts are available in ...
Bitumen Extraction Test
Bitumen Extraction Test is used to determine the percentage of bitumen content present in the asphaltic pavement by cold solvent extraction. The properties of flexible pavement such as durability, compatibility, and resistance from defects bleeding, raveling, and aging of flexible pavement ...
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 ...
