On the background of fixed bed, two factors including quantity of blending coal and the heating power, which influence pyrolysis characteristics of refuse blending with coal, were studied.

The research on testing of strength influence over high-performance concrete with flyash mixed in asperity condition in Qinghai-Tibet plateau;

The solution was increasing fly ash content and decreasing cement content largely.

Combining with the local raw materials,some factors influencing the impervious performance of the natural aggregate fly ash concrete in Xinjiang are discussed,and some parameters of the maximum water-binder rations and fly ash content for increasing the impervious performance of the natural aggregate fly ash concrete are proposed.

And the influence of stress level and fly ash replacement on neutralization of fly ash concrete was analyzed.

Test and evaluation on fracture characteristic of high content fly ash concrete;

Using mire and fly ash produce high content fly ash sintered brick is an effective way for developing new wall material that can save energy,make use of waste and protect environment.
