Applications and Importance of Non-destructive Tests on Concrete

Non-destructive tests (NDT) are widely used and play an important role in engineering projects including newly constructed and existing structures. For new structures, applications are mainly quality control or the resolution of doubts about the quality of materials or construction. ...
Test for Setting Times of Concrete Mixture Based on ASTM C403M-16

The penetration resistance test used for the determination of initial and final setting time of concrete mixture in laboratory and project site, and the effects of variables, such as water content; type and amount of cementitious material; or admixtures, upon ...
Types of Magnetic Concrete Cover Meter Equipment

There are several types of magnetic cover-meter equipment which are used to determine the thickness of reinforcement protector concrete. Commonly, these devices fall into nondestructive tests. Micro-cover meter, Pachometer, Profometer, NOVOTEST, and Cover Master are types of magnetic cover-meter tools. The ...
Determination of Elastic Modulus of Concrete in Accordance with ASTM C469

Modulus of elasticity of concrete is the ratio of normal stress to the corresponding strain for tensile or compressive stresses below the proportional limit of concrete, ACI 318-14. The value of elastic modulus of concrete can be obtained using formulas ...
Planning In-Situ Testing of Concrete for Strength, Durability and Damages

In-situ testing of concrete for strength, durability, performance and damages includes tests to show conditions of concrete and location of these tests are discussed.
Interpretation of Concrete In-Situ Test Results for Structural Strength Assessment

Concrete in-situ test results interpretation is important for structural strength assessment. Concrete test results interpretation consists of three stages from which proper conclusion are developed and its applications is discussed. In this article, different steps of result of concrete in-sit ...
Testing of Concrete Masonry Blocks for Compressive Strength and Density

Compressive strength of concrete Blocks or concrete masonry units are required to know the suitability of these in construction works for various purposes.
