An Intervention Study on Sisal Agave Sap as a Natural Concrete Admixture: Workability, Setting Time and Early Strength Development for Mombasa Construction in the Ethiopian Context

This study addresses a current research gap in African Studies concerning Sisal Agave Sap as a Natural Additive for Concrete Workability and Curing: Setting Time and Early Strength Development in Mombasa Construction in Ethiopia. The objective is to clarify key debates, identify practical implications, and outline a focused agenda for scholarship and policy. A mixed‑methods design was used, combining survey and interview data collected over the study period. The analysis indicates persistent structural constraints alongside emerging local innovations; however, evidence remains uneven across contexts and sectors. The paper argues for context‑specific approaches and stronger empirical foundations in future research. Stakeholders should prioritise inclusive, locally grounded strategies and improve data transparency.
