Synthesis and Characterization of Metakaolin‐Based Geopolymer for Industrial Application
Materials with enhanced properties are currently in high demand. Consequently, the ability to synthesize these materials efficiently, using low energy and without adverse environmental impact, has become a critical research priority. For this reason, geopolymers present an attractive prospect for researchers in material science and engineering. In this

Portland cement production is a major contributor to global CO2 emissions, and the scarcity of natural river sand limits conventional concrete production. Despite increasing interest in geopolymer concrete (GPC), studies on sustainable, low‐temperature cured GPC using industrial by‐products as fine aggregate replacements are limited.

Prediction of capillary absorption and compressive strength, applying multiple linear regression and artificial neural networks in concrete with natural pozzolana addition [PDF]
Cement is the fundamental binder of concrete, and its manufacture has a significant impact on the environment; therefore, it is necessary to look for eco-sustainable alternatives, including additions such as natural pozzolana, which affect the internal ...

This study investigates the mechanical and physical properties of mortars incorporating crushed hazelnut shell (HS) as a partial replacement for fine aggregates. Mortar mixtures were prepared with varying water‐to‐cement (w/c) ratios ranging from 0.35 to 0.50 and HS dosages of 2.5%, 5%, and 7.5% by weight, along with reference mixtures without HS.

The properties of fly and bottom ashes produced by Morupule power stations in Botswana are analysed for their pozzolanicity. Furthermore, the influence of physical, chemical and microstructural properties of the ashes on the performance of compressive strength of fly ash–based blended cement and geopolymer mortar was evaluated.
