In this paper, using sewage sludge carried out to manufacture high performance ceramsite. At the same time, the performance of concrete made from sewage sludge ceramsite was analyzed. The results show that the ceramist is mainly composed of cristobalite and mullet, and has dense enamel structure on surface and honeycomb closed fine porous structure in internal. Too large ceramsite size can caus...

To evaluate the effects of industrial by-products materials on the performance of porous concrete for plant growth, this study investigated the physical, strength, and freeze/thaw resistances of porous concrete for plant growth, prepared by replacing cement with blast furnace slag powder at 60% by weight, and replacing natural stone aggregates with coarse blast furnace slag aggregates at rates ...

The emergency break-away technology of civil aircraft is particularly important to the safety aircraft, and fuse pin key realization technology. A type pylon was taken as research object. Firstly, finite element structure model established by ABAQUS, explicit dynamic algorithm used study process load pins. Secondly, shear failure test designed verify accuracy model. Finally, influence diameter-...
