Preparation and Performance of Fly Ash Brick

Article Preview

Abstract:

This paper uses the industrialization production device to study the factors that affecting the performance of fly ash products. Through adopting the appropriate material ratio and technological parameters, the load-bearing standard bricks with large admixing amount of fly ash were successful developed. The mixing amount of fly ash has reached about 50%, and the bricks were got the production application in the industrialized device which annual output is 400 million pieces. The product performances are referred to the requirements specified in JC 239-2001, and the compressive strength reach 16.6 MPa and the breaking strength reach 3.8 MPa. The product has the low thermal conductivity and qualified freeze-thaw resistance, dry shrinkage. The products were got widespread popularization and application in the building construction of Qinghai-Tibet Plateau.
