Abstract: PURPOSE: A shock resistance testing device by collision with a high-speed projectile is provided to launch the projectile of various sources with one launcher, and to obtain shock resistance performance test data of a wide range by freely regulating a speed of a projectile depending on gas pressure and a sort of gas. CONSTITUTION: A shock resistance testing device comprises a gas chamber, a launcher, a carrier(100), a sphere flying body(200), a recovery chamber(400), a carrier separator, and a test piece fixing unit. The gas chamber receives a pestle, and an opening formed on the front side is sealed by a pressure sheet. The launcher is connected to the front side of the gas chamber to be joined to the opening. The carrier in a circular plate shape with the outer diameter corresponding to the inner diameter of the launcher is arranged inside the launcher.

Abstract: PURPOSE: A high strength fire resistant concrete containing polyamide fiber is provided to reduce the generation of cracks by dispersing polyamide fiber coated with a dispersing agent in the concrete. CONSTITUTION: A high strength fire resistant concrete includes 350-450 kg of cement, 150-200kg of water, 190-380 kg of fine aggregate, 700-900 kg of coarse aggregate, and 0.5-2.0 kg of polyamide fiber per unit volume. The design strength of the concrete is between 50 and 100 MPa. Admixture includes 40-80 kg/m^3 of fly ash and 150-300 kg/m^3 of slag fine powder. The external surface of the polyamide fiber is coated with a dispersing agent. The dispersing agent includes a poly-atomic alcohol ester lubricant, a nonionic surfactant, and an antistatic agent.
