Exploring the Impact of Silica-Rich Calcined Clay as Portland Cement Additive to Reduce Carbon Dioxide Emissions
Local clay, characterized, ground, and burnt, was used to partially substitute ordinary Portland cement (OPC) for mortar production. The raw clay burning was optimized to guarantee the lowest possible environmental effect with the highest possible reactivity of the calcined clay Fanja (CCF). The obtained clay pozzolana was used in mortar at (0–30%) proportions to partially replace OPC. The blended mortar was evaluated at fresh and hardened states, including the flow, compressive strength, and durability properties.
The findings show a decrease in the mortar’s flow, while the various CCF contents enhanced the compressive strength. Meanwhile, the mortar’s porosity and permeability decreased. The blended CCF mortars showed an impressive resistance to chloride compared to the plain mortar. Apart from its noteworthy mortar’s mechanical and durability performance improvements, the developed cementitious system is more cost-effective and environment-friendly compared to the control. This research advocates for using locally sourced, eco-friendly construction materials, as they enhance building performance and longevity and have minimal adverse effects on the environment and ecosystem.
