Low-energy cements and possibilities of their production
Original language description
Term “low-energy cements“ describes cements that can replace ordinary Portland cement in at least some applications and can also reduce energy consumption during the production process. An expansion of these cements could lead in both lower costs of binders production and lower emissions, CO2 especially. Belite cements are part of low-energy cements. Pure belite clinkers with interstitial matter comprising C3A and C4AF are not produced, since they yield materials with insufficient strength. Currently, sulfoaluminate-belite cements, lowenergy cements doped with fluorine and chlorine as well as undoped high-belite cements are produced in limited volumes in China. Results of hydraulic activation of high-belite clinker by sulfate anions are also given in this chapter. A principle of activation is the preparation of belite clinker with increased Ca:Si ratio in the structure of dicalcium silicate at substitution of SiO4 4- by SO4 2-. Cements prepared from these high-belite content clinkers with alite content up to 25 % that were burned at 1 350 °C display the same technological properties including early strengths as ordinary alite Portland cements.
