Manufacturing equivalent Clinker by indirect mechanosynthesis process

International audienceThis study is focused to the proposition of new cement manufacturing process. It is widely known that the cement production is responsible for a significant CO2 release each year (approximatively 4 billon ton). So, it is became necessary to find another cement manufacturing process with a minimum CO2 emission. The aim of this work is to manufacture equivalent clinker by indirect mechanosynthesis process. It consists to combine between mechanical activation of the raw materials (mixture of limestone and clay) and heat treatment less than 900 °C. The equivalent clinker obtained by this method shows the presence of the alite (tricalcim silicate) C3S and belite (dicalcium silicate) C2S and Tricalcium aluminate C3A. CO2 emission by this technique is estimated by 0.3 Ton for 1 Ton of equivalent clinker
