Stone‐Cutting Dust as a Sustainable Supplementary Cementitious Material: A Comprehensive Review of Its Physicochemical and Mechanical Effects

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Ordinary Portland cement (OPC) remains the most common binder used in construction and accounts for nearly 7%‐8% of the world’s CO2 emissions due to calcination of limestone and high energy use during clinker production. Reducing OPC content using SCMs is one of the major strategies to achieve sustainable construction.

Using Pozzolanic Materials to Improve Mechanical Properties of Lime‐Based Mortar

Journal of Chemistry, Volume 2026, Issue 1, 2026.
The environmental impact associated with the production of Portland cement has intensified interest in sustainable alternatives such as lime‐based binders. However, their application is constrained by low early strength and slow hardening. This study evaluates rice husk ash (RHA) and sugarcane bagasse ash (SCBA) as pozzolanic additives to enhance the ...

ACTIVATION OF RED KAOLIN CLAY AS A POZZOLANIC MATERIAL

Al-Qadisiyah Journal for Engineering Science, 2011
This work included two stages; in the first stage the optimum burning temperature to convert red kaolin clay to metakaolin was investigated. The red kaolin was burnt in a different temperature (800, 850, 900, 950, 1000, and 1050) ºC for one hour.

Use of Processed Biomass Ash as a Sustainable Pozzolana

Current Science, 2019
The industrial waste generated from sugar production, i.e. bagasse is further used as a biofuel. This generates a huge amount (44,000 tonnes/day) of waste in the form of sugarcane bagasse ash (SCBA). Asreceived boiler SCBA shows lower performance in terms of pozzolanic characteristics.
