Assessing the use of Activated Press Mud in strength of low grade concrete.
(Uganda Christian University, 2025-04-10) Allan Jesse Kirabo
Concrete is the most widely used construction material globally, valued for its benefits in cost and versatility. There are many classes of concrete one of being low grade concrete. The purpose of this research was to assess the use of activated press mud in enhancing the strength of low-grade concrete. Activated press mud contains pozzolanic compounds that react with calcium hydroxide to form calcium silicate hydrate which enhances concrete strength. To evaluate its effectiveness, activated press mud was used to partially replace cement at 0% - 20%. X-ray fluorescence, loss on ignition, Chapelle test, specific gravity, slump test and compressive strength were done. Results confirmed pozzolanic properties and contribution to concrete strength. Slump results showed workability remained within acceptable limits (25 mm - 50 mm). Most notably 44% increase in compressive strength was observed upgrading concrete from class C15 to C20. The findings support the adoption of industrial waste materials in concrete production to reduce cement consumption and environmental impact. It is recommended that further studies explore long-term durability and field performance to optimize its application in large-scale construction projects.
