A-mechanical properties of engineered cementitious composite concrete produced from Portland limestone cement

Abstract

Conventional concretes are almost unbending, and even a small amount of strain potential leaves them brittle . This lack of bendability is a major source of strain loss, and it has been a driving force behind the development of bendable concrete, often known with engineered cement composites, or ECC. This form of concrete has a lot more flexibility than regular concrete. Micromechanical polymer fibers are used to strengthen ECC. In most cases, ECC uses a 2% amount of thin, separated fibers. As a result, bendable concrete deforms but does not crack any more than traditional concrete. This study aims to include this kind of concrete, bendable concrete, which can be used to solve concrete problems. Karasta (CK) and Tasluja (CT) Portland Limestone Cements were used (CT). The polypropylene fibers (PP) and polyvinyl alcohol acetate (PVA) were used to make four different mixes. The experiments were performed at 7, 28, 66, and 90 days after water curing. For all tests, mixes including pp fibers and PVA solution performed better than those without fibers.
