STUDY ON THE COMPOSITION AND HYDRATION OF ALINITE AND CALCIUM CHLOROALUMINATE MINERALS

Ecocement is a new type of cement produced with recycled materials, including wastes such as the residue from municipal waste incinerators. The main clinker minerals are alinites and calcium chloroaluminates. This article studies the composition and hydration mechanisms of these minerals by scanning electron microscope (SEM). The authors synthesized the minerals, then analytical reagents are mixed into the raw meals of alinite and calcium chloroaluminate that are burnt under different temperatures. The authors conclude that the alinite and calcium chloroaluminate mineral have good compressive strength. The optimal condition of calcium chloroaluminates is at the firing temperature of 1300 deg C. for 2 hours; alinite synthesized at 1375 deg C. for 2 hours.
