Abstract
In this segment of our research, our primary objective revolves around the exploration of the feasibility of formulating high-performance, durable, and cost-effective concrete compositions through the utilization of locally sourced mineral additives. Our investigation also delves into the impact of these additives on two distinct concrete types: heat-treated concretes subjected to steam treatment and those left untreated. We experimented with three different types of additives, each at varying proportions of 10%, 20%, and 30%.
The adopted heat treatment regimen was characterized by a peak temperature of 60°C and an overall duration of 24 hours. This research aligns with the principles of sustainable development by emphasizing the development and efficient utilization of materials readily available in Algeria's cement industry.
The outcomes of our study are indeed promising. We can confidently assert that it is feasible to produce durable and cost-effective High-Performance Concrete (HPC) using locally sourced materials in Algeria. Furthermore, the mineral additives employed in our study conform to the criteria of pozzolanic materials, as stipulated by the ASTM C 618 standard. This research not only contributes to the advancement of construction materials but also supports Algeria's endeavors towards sustainable and economically viable practices in the construction industry.
