Yuyang coal mine and Tiandi Science & Technology Co., Ltd made aeolian sand as aggregate of stowing material and developed aeolian sand Paste-like stowing material, which can solve the imbalance problem of the demand of stowing materials and reduce the material cost.
In order to solve these problems, according to the characteristics of stowing materials in Yulin area, researchers of Tiandi Science and Technology Co.
Ltd developed auxiliary cementitious materials of stowing materials (auxiliary materials).
The main components of auxiliary materials are lime, desulphogypsum and additive.

Composite materials, such as CFRP, are hard-to-cut materials but their specific strength is useful.
In the present report, we investigated the material-removing mechanisms of the blast from the viewpoint of the erosion abrasion, considering the most suitable method through changing work materials and processing conditions such as abrasive and pressure. 1.
The experiment conditions and abraded materials used as the specimens are shown in Table 1.

Effect Of Different Sintering Temperature On The Performance Of Mullite-Corundum Refractory Materials LI Ping1,2, GU Xing Yong1,2,a, LUO Ting1,2and Chen Yun Xia1,2 1Jingdezhen Ceramic Institute, Jingdezhen, Jiangxi, 333403, China 2Jiangxi Provincial Key laboratory of advanced ceramic materials, Jingdezhen, Jiangxi, 333403,China aguxing-y@163.com Keywords: Sintering temperature; Mullite whisker; Formation in-situ; Refractory materials Abstract.
The mullite-corundum refractory materials with well-dispersed needle-like mullite formed in-situ were prepared.
Secondly, calcined bauxite and Suzhou kaolin, the raw materials of the sintered materials, were weighed, wet grinded, dried and then sieved by 120 meshes.
Finally, the grinded and sieved raw materials of the sintered material and the granulated precursors of mullite whisker were weighed respectively and mixed uniformly according to the designed mass ratio of 7:3.

The critical density between masonry materials and lightweight materials is defined as 2000kg/m3 here.
The result of Fig.1 (a),(b), which shows that the coupling loss of masonry materials less than materials can also prove it.
Fig2 (b) shows the η RW of lightweight materials, which value is less than masonry materials at the same frequency.
It means that sound insulation performance of masonry materials is better than that of the lightweight materials.
