The paper presents the development of a similar material to simulate the soft rock type in engineering, especially the time-depending behavior. The iron, barite and cement are selected to be the aggregate and the solution of rosin is selected as the glue. To improve the plasticity and rheology behavior, chlorinated paraffin was added, too. Laboratory test was carried by construct the specimens using a mould. The uniaxial complex modulus test and indirect tensile strength test were performed to obtain the basic mechanical behavior. And the rheology test was carried by a self-developed rheology test machine to research on the time-depending behavior. By laboratory test, the influence of the each component on the mechanical behavior was determined. Results show that the effects of component ratio and solution thickness on the material mechanical behavior. The rheology behavior was especially well simulated by the similar material developed.

ABSTRACT A bewildering variety of materials has been suggested for the removal of spilt oil from beaches, rocks and shore-line structures. These vary considerably in composition, toxicity, efficiency and cost. Early laboratory test procedures developed in 1961, were concerned only with efficiency in cleaning and were demonstrably non-reproducible. Since that date considerable efforts have been made to refine the procedures in use, and to introduce new tests closely allied to the beach cleaning process. A co-operative exercise, undertaken in conjunction with the maljor oil companies of the United Kingdom demonstrated the degree of agreement between laboratories that could be expected from such standardized test procedures. Recent developments in this field at Warren Spring Laboratory, and the procedure at present used for the assessment of these materials for beach cleaning in the United Kingdom are described.

This paper discusses the current methods used to test electrostatic pulverised fuel meters in a laboratory environment and the precautions to be taken to ensure that meaningful results are obtained. In particular, the effect of particle attrition is discussed and results presented from a laboratory test facility at the University of Teesside.
