Paper Title:
Study on Using Low Quality Fly Ash to Produce Baking-Free Bricks
  Abstract

In this paper we studied the feasibility of baking-free bricks which were produced in condition of high pressure and natural curing. Studied the influence of shaping pressure, molding water on performances of baking-free bricks, and the active probability of activating agents which contain phosphogypsum, and lime of different amounts. The experiments showed that the best shaping pressure is 20MPa, the preferable molding water is 14-18%, and the best raw material composition is 50% fly ash, 33% stone clips, 4% phosphogypsum, 3% lime, and 10% cement. SEM was used to study the relationship between structure and performance.
