Experimental Study on Bio-Self Cured Marble Powder Based with M-25 Grade Concrete

Abstract

Water is most widely used in construction activity for first phase to mix material and final phase to curing. In first phase, we mix water in concrete to achieve workability. Without workability concrete cannot be used for construction. Curing is the most important phase for achieving strength. But now-a-days more problems for water because water is falling in its quantity in environment, so in place of water there an urgent requirement to find substitute to make concrete and for construction works. However, it is not possible to provide sufficient curing because of many causes like different environment, availability of water, fluorides and inattentiveness of human. In this way, it is necessary to invent the self-curing agents prepared by different method like using Biomaterials (Calatropis gigantea, Spinacea oleracea) and chemical admixture (polyethylene glycol) along with waste environmental material i.e. marble powder or dust. Hence, to reduce consumption of water, some admixtures i.e. marble powder, PEG-400, calotropis gigantea and spinacea oleracea were used in such manner so that there was no bad effect on workability, compressibility, split tensile strength, flexural strength of concrete. Marble powder is a by-product of stone industries and affects the environment badly, when thrown in an open area. In this way, 10% of marble powder used in place of cement was appropriate quantity in concrete. It is observed that concrete of M25 grade, mixing with 10% of marble powder and 1% of polyethylene glycol - 400 gives optimum result when compressibility, split tensile strength and flexural strength tests were performed and examined for 7 and 28 days.
