Quality Control of Concrete On Site (Part 2) - Federal Highway Administration 1994 - Video VH-274 - Tests for on-site quality verification of concrete are demonstrated in this series of four tapes. Parts 1 and 2 show conventional control tests, with demonstrations of sampling methods, tests for temperature, and a very clear, detailed demonstration of the slump test (AASHTO T-119). Tests are shown for air content and unit weight, and procedures are given for forming cylinders and beams onsite for subsequent compressive and flexural strength tests.
