Home LC3 Limestone Calcined Clay Cement

LC3 is a new type of cement that is based on a blend of limestone and calcined clay. LC3 can reduce CO2 emissions by up to 30%, is made using limestone and low-grade clays which are available in abundant quantities, is cost effective and does not require capital intensive modifications to existing cement plants.

Overview

The Material LC3 Limestone Calcined Clay Cement

Calcined clay and limestone are already commonly used as Supplementary Cementitious Materials (s). The major innovation in LC3 is to combine the use of abundantly available low-grade kaolinite clay with a further 15% of limestone, with no reduction in mechanical performance.

Calcined clay limestone cements (LC3) ScienceDirect

01.12.2018· Clays containing about 40% kaolin or above give strengths comparable to plain Portland cement when used in LC 3-50 (50% clinker, 30% calcined clay, 15% limestone and 5% gypsum). Such clays are widely distributed and, as clay is often one of the raw materials for cement production, may even be available in existing quarries of cement plants.
