The Influence of Production Parameters on Pozzolanic Reactivity of Calcined Clays

Nordic Concrete Research, 2018
Calcined clays are gaining increasing interest as future supplementary cementitious materials for the production of blended cements. Besides the mineralogy, the right production conditions can affect the pozzolanic activity of calcined clays.

Microbial Deterioration Potential and Mitigation Strategies in Blended Cement Structures: A Review

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Microbial‐induced deterioration (MID) is a threat to the durability of cement‐based materials (CBMs) particularly in sewer and wastewater systems. Whereas blended cements incorporating supplementary cementitious materials (SCMs) offer environmental benefits such as reduced carbon (IV) oxide (CO2) emissions and enhanced mechanical performance, their ...

Enhancing Expansive Soil Stability Using Agricultural Waste: Soybean Pod Ash and Banana Fiber

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study evaluates the efficacy of agricultural waste—soybean pod ash (SBPA) and banana fiber (BF)—as sustainable stabilizers for expansive soils in Jimma Town, Ethiopia. Soil samples from Kebele 5 and Ajip Kela (1.50 m depth) with the highest plasticity indices and lowest California bearing ratio (CBR) values were selected.
