Concrete Construction and Standard A23.2-14 Test Methods and Standard Practices for Concrete describes the standards and test methods respectively, this document is intended as a guideline to provide additional commentary regarding best practices which can be used for field testing and sample collection.
30 Ιουν 2019 · The impulse-response test is one of the most versatile nondestructive test (NDT) methods for condition assessment of concrete structures. It is an elastic stress-wave propagation based low-strain and low frequency NDT method, which is widely employed in the NDT industry.
8 Οκτ 2019 · As shown in Fig. 2, the relevant testing and evaluation methods are: (a) ETAG 029 Annex B, Metal injection anchors for use in masonry, recommendations for tests to be carried out on construction works (b) ETAG 020 Annex B, Plastic anchors for multiple use in concrete and masonry
Non-destructive tests of concrete is a method to obtain the compressive strength and other properties of concrete from the existing structures. This test provides immediate results and actual strength and properties of concrete structure.
studied how material properties (concrete age, pore content, aggregate type, and reinforcement density) affect thermal images for damage (voids) detection of plain and reinforced concrete specimens in the form of slab structures. A thermal heating unit set up with three infrared radiators (each with 2400 W) was used.
The primary quality test determines the variation of the concrete specification from the required and standard concrete specification. The quality tests ensure that the best quality concrete is placed at the site so that concrete structural members of desired strength are obtained.
9 Ιαν 2020 · When compression test on concrete cylinders yield low breaks, engineers require reliable tools to assess the actual strength of concrete. Nondestructive testing (NDT) offer an interesting approach to evaluating the compressive strength of concrete.
