Its strength depends on the characteristics of its constituents. A good mix makes it possible to build solid, durable and economical structures. The present work aims to characterize the gravel of the Eastern region (quarry of eastern Morocco) by granulometric analysis and water absorption. Then, the studied gravel is used to produce three types of concrete (B20, B25 and B30), which were assessed in terms of water absorption and compressive strength. The last step is to study the effect of an adjuvant, more specifically a water reducer, on mechanical characteristics of local concrete. B25 concrete was chosen for the last step since it is the most used type in the region. Results show that adding a water reducer adjuvant, in this case ‘Chrysoplast’, can improve the compressive strength of concrete if the percentage added is accurately determined. Keywords: Concrete, Compressive strength, Gravel, Water absorption, Chrysoplast 1. Introduction Concrete is the most consumed manufactured material in the world, with around three tons per person each year. Its manufacture is justified by its low cost and availability of its components. However, with a view on sustainable development, a similar position in terms of manufacturing and consumption makes its impact on the * Corresponding Author
