Paper Title:
Experimental Research on Environmental Friendly Ash Aerated Concrete
  Abstract

Aerated concrete is kind of normal silicate products, which is made by hydration of lime, cement, gypsum fly ash/sand, forming agent. And it has become the major wall material of frame structure caused by its characteristics of light weigh, high strength, and heat insulation. Petroleum coke is the by-product of delayed coking system in oil refinery. Oil refinery in coast area of east China mainly exploits high-sulfur crude oil from Middle East. The petroleum coke contains even 5-8% sulphur, and calcium injection desulphurization is usually employed to reduce the SO2 emission, and leads to that Ca/S of reaction is up to 2.0-2.5. Therefore, there remain many unhydrated Lime and desulfurized gypsum in petroleum coke. It presents drying powdery and a favorable cementing performance. In this paper, chemical and mineral compositions of petroleum coke desulfuration residue are analyzed by means of X-ray fluorescence spectrometer and X-ray diffracto-meter. And lime and gypsum are replaced by petroleum coke desulfuration residue to produce aerated concrete. The experimental results indicate that products made of high-sulfur petroleum coke desulfuration residue and fly ash has better performance than traditional lime aerated concrete products. The fly ash-desulfuration residue aerated concrete products possesses the dry density level of B06 [1] and strength of 4.5MPa. Consequently, it should have expansive application potential because of their prominent economic, social, and environmental benefits.
