Chemical testing of hardened concrete is mainly limited to the identification of the causes of deterioration, such as sulphates or chlorides, or to specification compliance, involving cement content, aggregate/cement ratio or alkali content determination. Water/cement ratio, and hence strength, is diff...

Objective of present experimental study was to thoroughly investigate normal weight hardened concrete specimens by a static ball indentation hardness testing laboratory device at several load levels on a wide range of compressive strength and age of concrete at testing. It was found that the power in...

Durability testing is important to determine the lifespan of your structure. BS EN 12390-8, Testing Hardened Concrete: Depth of Penetration Under Water Pressure, and DIN 1048 Part 5, Testing Concrete: Testing of Hardened Concrete Water Permeability, are equivalent tests that measure the depth of ...
concretemortarIn this research paper, we show microwave reflection and transmission properties measured from various sides of hardened mortar and concrete specimens with different water-to-cement ratios. These properties are important in predicting/measuring accurate electrical properties of cement-based ...
