There are some assumptions in numerical model as following: (1) The piles foundation deals with as composite materials, and parameters calculate according to the exchange rate of piles and soils
(2) The bottom of chimney deals with as composite materials too, and parameters calculate according to the rate of the chimney and filling soils

Experimental procedure Experiment used TiFe (w(Ti)=30%), FeNCr(w(N)=5%, w(Cr)=60%) and toner as raw materials, and mixed the raw materials within the ratio of 190.5:100:10, the mixed powders were prepared with the processing of 6 to 1 ball to powder weight ratio and wet mixing 4h with absolute alcohol as medium in YXQM-1L planetary ball mill.
Analysis and discussion Essentially the sintering process of composite materials is an energy and material transfer process, composite materials system will get to a steady equilibrium state as the sintering process go on,on the premise of the same dwelling time, sintering temperature decide whether the sintering is fully.
(2) The composite materials have low shrinkage rate, hardness, bending strength,and fracture toughness when the temperature is less than 1150℃, and when temperature is greater than 1150℃, materials have obvious shrinks, the fracture toughness and bending strength rise according to the trend of fast followed by slow with 1200℃ for turning point

Thus, after the great performance of fly ash and GGBS as supplementary cementitious materials is identified and recognized by the construction industry, it is not surprising that there has been a lot of interest in the development of less energy intensive and more ecological mineral materials in massive replacement of cement clinker, such as artificially-made materials, industrial byproducts or natural materials.

Materials and Methods Plant materials and experimental design Three varieties (variety A, B, and C) of maize (Zea mays L.) were selected as the plant materials.
Thus, these materials are considered as the maize varieties gone through long-term heavy metal contamination.
The seeds of three varieties are supplied by Academy of Agricultural Sciences of Yunnan.
