Eco-efficient alkali-activated cement based on red clay brick wastes suitable for the manufacturing of building materials

Autor: Johanna M. Mejía-Arcila, Ruby Mejía de Gutiérrez, Rafael Andres Robayo-Salazar

Publikováno v: Journal of Cleaner Production. 166:242-252

The objective of this study was to obtain hybrid-type binders at room temperature (25 °C) from the alkaline activation of a red clay brick waste and the addition of a reduced amount (≤30%) of Portland cement. Different types of activators were use
