Experimental Study on Damage Breakage Properties of Shaft Lining Concrete under Hydromechanical Coupling

Different Damaged Shaft Lining Concrete Resistance to Sulfate Corrosion

Shaft lining concrete itself has a certain degree of initial damage before being corroded by sulfate. In order to study the resistance of the concrete of the initial damage in different corrosion solution concentration of sulfate, samples of concrete without initial damage, loaded 50% ultimate load and loaded 70% ultimate load with initial damage concrete were selected and studied their corrosi...

Experimental Study on Performance of Fiber Concrete-filled Tube Columns under Axial Loading

There have been great developments in the area of civil engineering in the recent few decades and among these, construction and material innovation are quite prominent. Steel-concrete composite construction has emerged as one of the fastest methods of construction. Even though considerable research efforts on conventional reinforced concrete columns have been executed prior to now, concrete fil...

Experimental Study of Damage Evolution in Circular Stirrup-Confined Concrete

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...

Damage Detection of Carbon Fiber-reinforced Concrete Under Bending Test

Experimental study of impact strength and modulus of elasticity of reinforced concrete under ambient temperature, used in concrete dams

The choice of concrete consumption and high strength in the structure of concrete dams is of particular importance. In this laboratory research, slag alkaline concrete containing 0, 4 and 8% nanosilica and 1 and 2% polyolefin fibers has been produced in 5 mixing designs. A design of control concrete containing Portland cement was prepared to compare with the test results of reinforced concre...
