Cement and concrete testing helps assure compliance with quality assurance aspects like mix designs, production control, and efficient materials usage, which are largely dependent upon the quality of cementitious mixtures. There is an extensive range of testing methods and techniques that can be carried out to determine concrete quality and suitability, which is why it is critical to find the correct design and tool for the physical testing of these products. Concrete testing tools are varied and some are specifically designed for testing different characteristics and qualities of cement and concrete, ranging from permeability to soundness, specific gravity, consistency, expansion limit, and other physical as well as chemical aspects of materials. Vibrating table – A vibrating table tests the flexural or compressive strength of cement and concrete, which is essential if you want to achieve a more consistent mixture.

Corrosion potential mapping is used to identify rebar spots that are undergoing corrosion. It is a non-destructive technique carried out on concrete structures in order to determine corrosion status related to the identified corrosion potential value. The contours and measurements obtained by using plotting potential corrosion values are also significant in delineating corroding portions of structures from "healthy" non-corroding portions. The half-cell, open circuit potential test method is a more frequently used technique for potential corrosion mapping, although double-probing is also applicable. The half cell testing method is suitable for on-site (in-situ) evaluation as well as for research and development work. It applies to concrete members regardless of size or depth of covers over reinforcing steel.  Half-cell circuit potential testing and measurement can also be used any time during the lifespan of a concrete member. It is an inexpensive test method that i...
