WebCompression test is the most common testing conducted on hardened concrete, partly because it is an easy test to perform, and partly because most of the desirable characteristic properties of concrete are qualitatively related to its compressive strength. The compression test is carried out on specimens cubical or cylindrical in shape. Prism is ... WebHowever, limitations imposed by the encased cement concrete, e.g., its brittleness, low tensile strength and diminished durability, further compounded by mounting environmental concerns since the 1997 Kyoto protocol and the need for sustainable development, dictate that novel ecologically benign construction materials be sought for the 21st ...
