This paper presents an experimental study on circular stirrup-confined concrete specimens under uniaxial and monotonic load. The effects of stirrup volume ratio, stirrup yield strength and concrete strength on damage evolution of stirrup-confined concrete were investigated. The experimental results showed that the strength and ductility of concrete are improved by appropriate arrangement of the...

Mussel shell is a type of waste that generated abundantly. However, the presence chemical components such as calcium (CaCO3) in mussel shells has shown its potential filler materials concrete designing. Therefore, this paper presents experimental result for physical and mechanical properties containing 1%, 2%, 3% 4% Shell Powder (MSP) additional material under 2.73% sodium chloride solution. Th...

Submit Manuscript | http://medcraveonline.com interaction of airplane body with the shell has been replaced by impulse. Such approach is justified when initial stage of interaction is described, taking that concrete structure contacts quite thin aluminum body (from 3 to 8 mm thick). In this case one does not need to calculate contact boundaries thus simplifying significantly the objective and e...

The utilization of aquaculture waste, such as snail shells, is a severe issue. These shells are common in water-sources and by-product sifting sand for masonry concrete work. Calcium-rich river great interest cement building materials. In this regard, the purpose article was to develop nanomodified with improved characteristics based on powder shells. Experimental studies have confirmed effecti...
