Quality Assurance in Concrete Construction Quality Assurance in Concrete Construction: The quality of the concrete in construction is an essential consideration. Concrete is used for everything from foundations to exterior and interior walls, to floors, to counter tops, to many other applications. Quality assurance in concrete construction is a huge part of any project that …
Outlining Various Tests on Concrete Outlining Various Tests on Concrete: Concrete quality tests are conducted as part of the quality management process for concrete buildings. Numerous concrete consistency checks, like compressive strength and slump tests, are applied to ensure the quality of the concrete supplied to meet a specified specification. These tests provide information about the …
Limitations of Schmidt Hammer Test Limitations of Schmidt Hammer Test: While the rebound hammer is an efficient and economical method of testing the uniformity of concrete, it does have significant disadvantages that must be understood. The Schmidt rebound hammer’s findings are influenced by: Smoothness of the Tested Surface The texture of the surface has a major …
Schmidt Hammer Test on Concrete Schmidt Hammer Test on Concrete: In 1948, Ernst Schmidt, a Swiss inventor, invented a test hammer for determining the hardness of concrete using the rebound principle. The hammer was designed and thoroughly tested at the Swiss Federal Materials Testing and Experimental Institute in Zurich as a result of his work. …
Setting Time of Concrete: The penetration resistance test is used to determine the initial and final setting times of concrete mixtures in the laboratory and on-site, as well as the effect of variables e.g. water content; form and quantity of cementitious material; and admixtures on the setting time of concrete. The setting time test is …
Measuring the Temperature of Fresh Concrete: ASTM C1064 is the standard that is used to determine the temperature of fresh concrete to guarantee that your concrete fits within the specification limits. Temperature of concrete at the time of mixing will influence the method of concrete curing later on, and accordingly strength development. In this article, …
