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. ...
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. ...
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 ...
5 Monitoring Techniques for Early Strength Gain of Concrete in the Field

Monitoring early strength gain of concrete in the field is crucial task for the success of some construction works like starting critical shoring and reshoring steps which is required during multi-storey building construction and removal of formwork. There are several ...
Workability of Concrete by Kelly Ball Test

Kelly ball test also called as a ball penetration test is performed on freshly mixed concrete to measure its workability. It is a quick simple field test and is considered as an alternative to the slump test. The test procedure ...
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 ...
Hot Weather Concreting – Effect of Hot Weather on Concrete

Hot weather has a significant effect on all stages of concrete production and placement procedures such as increasing rate of hydration and movement of moisture from within and surface of the concrete. It affects long term strength and durability. Hot ...
