... are prepared by using the hand layup method followed by the vacuum bagging process. Mechanical properties like flexural, tensile, hardness, and impact properties are evaluated in this article. The dry sliding wear behavior of three different laminates is carried out with pin on disk by varying time, speed...

.... The performance of control concrete and two kinds of recycled coarse aggregate concretes were studied experimentally with respect to mechanical properties. Results indicate that the processing method to obtain recycled coarse aggregates plays an important role in developing the required mechanical properties...

...-strength counterpart. This paper thus presents a study into engineering characteristics of higher-strength CRC and its benefits to the environment, as well as investigates the ability of micro crumb rubbers to enhance CRC’s mechanical properties. The results revealed that replacing fine aggregate...
