The concrete surface deteriorates due to abrasion by sliding, scraping, percussion, or action of abrasive materials carried by water. The abrasion loss of a specimen exposed to an abrasive charge is used to determine the relative resistance of concrete surfaces in this standard […]

Explained with Video https://theconstructor.org/concrete/variations-concrete-slump-site/185442/ Fri, 05 Feb 2021 11:38:00 +0000 https://theconstructor.org/?p=185442 Adjusting the slump of concrete is a part of the concreting process, which the contractors should manage properly and cautiously. The concrete slump variation from one transit mixer to another is generally due to aggregate moisture content, concrete temperature, mixing process; and time of delivery, waiting, and unloading. Sometimes, the concrete slump variations at site […]

This test gives a fair idea about the quality of the concrete that is being poured at the site. While conducting this test, the major question that emerges in front of a site engineer is – How many Concrete Cubes to […]

The types of linings used in a water-containment structure, their location (semiarid or arid area, covered or not), and ambient temperature are used as factors to determine the watertightness of a structure. The test […]

The test involves the measurement of the increase of mass of concrete samples resulting from the absorption of water as a function of time when only one face of the specimen is exposed to water. The concrete specimens […]

Here is What you Should do https://theconstructor.org/concrete/site-slump-test-fails/176167/ Sat, 10 Oct 2020 03:26:00 +0000 https://theconstructor.org/?p=176167 Engineers should make a proper decision when an on-site slump test fails. The decision could be an outright rejection of the complete batch of concrete or the suspension of the work due to the contractor’s failure to follow project requirements. Alternatively, the client may permit the contractor to continue the work and wait to see […]

]]> 176167 How to Test the Temperature of Fresh Concrete as per ASTM? https://theconstructor.org/practical-guide/test-temperature-fresh-concrete-astm/66681/ Thu, 24 Sep 2020 16:46:06 +0000 https://theconstructor.org/?p=66681 The temperature of fresh concrete can be determined as per ASTM C1064 to ensure the concrete’s conformity with standard temperature specifications. The method employs a calibrated thermometer to test the concrete temperature. The temperature of the concrete affects the way it cures, and the final-strength gain. Hence, it is necessary to test the temperature of […]
