Activator on Properties of Red Mud Lightweight Baking-Free Brick

Abstract:

Red mud lightweight baking-free brick was prepared by red mud, fly ash and cement. The influence of activator on properties of red mud lightweight baking-free brick was studied. The micro-structure of red mud lightweight baking-free brick was characterized by scanning electron microscopy (SEM). The results show that when the activator content is 1%, the sample with better performance obtained and the flexural strength increased by 64.4%, the compressive strength increased by 44.1% compared with the blank style.
