FA, a by-product from coal combustion, has been widely utilized for concrete production because of its beneficial effects on the engineering properties of concrete.
Incorporating this by-product can improve the engineering characteristics of concrete.
To study the effect of BA incorporation on the engineering characteristics of concrete pavement, BA was used to replace 50% and 100% (by volume) of crushed sand in the concrete mixtures.
The flexural strength is an important parameter used to assess the engineering quality of concrete.

Industrial test on outer frozen shaft wall of high strength and high performance concrete YUE Zhong-wen1, a, ZHANG Hui1, b, DOU Bo-yang1, c 1School of Mechanics & Civil Engineering, China University of Mining & Technology, Beijing, China azwyue75@163.com, bzkzhh@qq.com, clemoond@qq.com Keywords: high performance concrete; frozen shaft wall; microcosmic and microscopic mechanism; construction technology; industrial test.
At present, overseas such as Japan, the United States, Canada and some other countries mostly research on high performance concrete, but they only focuses on surface engineering.
Thus, in this paper the engineering test of outer shaft wall of C100 high strength and high performance concrete was carried out based on the auxiliary shaft in Yuncheng Coal Mine of Juye coal mining area in Shandong Province.
Engineering situation The designed caliper of auxiliary shaft in Yuncheng Coal Mine is φ7.2m and the full depth is 936.8m, in which the topsoil thickness is 536.65m and the frozen depth is 594m.
