Tips on Measuring for Concrete. Your measurement methods will shift depending on the shape of your future concrete slab. For example, you’ll measure a rectangular shape using length and width. A circular shape requires that you find the diameter. Once you find the dimensions of your slab, input them into the calculator along with the thickness.
Measurement of steel reinforcement corrosion in concrete is essential to analyze the strength and durability of a structure. Not only does the steel corrosion reduce the life span of the structure but also increases the cost for inspection and maintenance significantly.
Compressive strength is an effective way of measuring how much load a surface or material can bear. The test for this sort of strength is performed by exerting force downward on top of the object, paired with an equal and opposite force exerted upward on the bottom.

Jan 12, 2017 · This articles reviews some of the most accepted and widely used nondestructive tests of thickness measurement for concrete elements. Thickness measurement can be of interest for engineers and technicians involved in the assessment of existing concrete elements, such as slabs, foundations, or pavements, or as a means of quality control (QA) in the construction of new concrete pavements.
However, measurement points must be selected carefully and it is sometimes very difficult in case of structures with unknown factors such as, structural deterioration or boundary condition. Non-reusable strain gauge means inflexibility of measurement points. Therefore conventional strain gauges are unsuitable for short term measurements.
