Abstract

To understand the effect of different natural and chemical admixtures on the properties of conventional and high strength concrete, an extensive literature review was done. It is known that chemical admixtures are composed of substances that are added to concrete to improve different aspects in fresh and hardened states and polycarboxylate PCE is one of the admixtures that have significantly contributed to the development of conventional concrete. Since the effect of different types of chemical admixtures can arise when concrete particles containing admixtures is dumped after a building has been demolished or when they are thrown out into the surroundings, Therefore, it is required to identify alternative admixtures that improve the qualities of concrete without negatively impacting the environment. Various natural organic elements have been studied incorporated in concrete and mortar in the past and recently. There are Organic admixtures such as molasses, black gram, potato starch, egg white, and cactus adhesive juice etc. are among the organic substances that enhance the workability, compressive strength, tensile strength, plasticity, and durability, etc. throughout this work the behaviour of natural plant extracts used as admixtures and fibres in concrete with and without the combination of certain types of other admixtures have been explored.
