Limestone Calcined Clay Cement - Wikipedia
Limestone Calcined Clay Cement is a low-carbon alternative to the standard Portland cement. [33] [15] LC3 can reduce CO 2 emissions related to cement manufacturing by reducing the amount of clinker, replacing it with finely ground limestone and calcined clays.
Calcined clays - GCCA
Calcined clay – or metakaolin – is produced by heating a source of kaolinite to between 650°C and 750°C. Kaolin is both naturally occurring, as in china clay deposits and some tropical soils, as well as in industrial by-products, such as some paper sludge waste and oil sands tailings.
Clay calcination technology: state-of-the-art review by the …
This paper, produced by RILEM TC 282-CCL on calcined clays as supplementary cementitious materials (working group 2), focuses on the production of calcined clays, presents an overview of clay mining, and assesses the current state of the art in clay calcination technology, covering the most relevant aspects from the clay deposit to the factory ...
Calcined clay - concretecentre.com
Calcined clays are one the materials that are classed as “natural calcined pozzolana” in the European standard for cement, EN 197-1. This allows cement producers to make a range of cements with up to 55% of the Portland cement clinker replaced by calcined clay.
The Calcined Clay Way | World Cement

Calcined Clay as Supplementary Cementitious Material - MDPI
Oct 23, 2020 · Calcined clays are the only potential materials available in large quantities to meet the requirements of eco-efficient cement-based materials by reducing the clinker content in blended cements or reducing the cement content in concrete.
Impact of calcination technology on properties of calcined clays
Sep 18, 2024 · The objective of this paper is to investigate the impact of the calcination regime on the properties of the calcined product. It presents the results of an experimental program carried out with a kaolinitic clay calcined at a flash calciner and at a laboratory furnace.
