Fresh, Mechanical, and Durability Properties of Concrete Contains Natural Material as an Admixture, an Overview

Abstract

Nowadays, the performance criteria for concrete construction are moving toward eco-effi-ciency, a method of producing highly durable and environmentally friendly concrete while min-imizing both manufacturing costs and environmental load. Admixtures are commonly used in all concrete construction; however, some harm human health and cause leaching, which is re-sponsible for environmental pollution. On this principle, one of the eco-efficiency method's techniques is to use natural materials as additives in concrete. The paper continues to discuss the experimental data generated at the author's laboratory as part of exploratory work on the use of natural materials and their impact on the properties of cement, mortars and concretes in terms of improving fresh, mechanical, and durability properties of concrete, The paper concludes that the observed impacts of using these natural material additions on the properties of mortar and concrete will motivate greater research in these areas, thereby improving the sustainability of concrete constructions.
