Optimizing Self-Compacting Concrete through the Incorporation of Calcined Mud at 850°C

Abstract

The quantity of mud increases annually at dam sites, thereby reducing their storage capacity. To extend the lifespan of these structures, dam dredging is an essential solution. However, the extraction of enormous amounts of mud through the dam's bottom outlets, which remain unused, currently poses an environmental problem.

The primary objective of this research is to study the influence of mud, after thermal treatment at 850°C, added as an additive on the behavior of self-compacting concrete (SCC).

The first section of this article aims to detail the steps and essential processes for obtaining high-quality self-compacting concrete, incorporating calcined mud as an additive while adhering to current standards. The second part presents results related to mechanical compressive strength and split tensile strength concerning age.
