Analysis of the mixing performance containing the LC3 as agglomerant with different types of calcined clay

Abstract

Given the growth of the construction industry in recent years, Portland cement production has been increasing, but the cement industry is adversely affected by sustainability, accounting for about 5% of the world’s CO2 emissions. With the view to reduce these emissions, mitigating measures have been analyzed, and one of the most promising ones is the reduction of clinker/cement ratio, using as substitution mineral additions. This research aims to analyze the mechanical performance of mortars from the use of cement with addition of two types of metakaolin, one of these being more reactive, with the addition of limestone. From the characterization of these materials and the different substitution contents used from binary and ternary mixtures, it was verified that some of them have a good performance.
