What is a typical concrete abrasion resistance?
Several factors influence the abrasive qualities of a concrete surface. Mix design, exposure conditions, placement and finishing regimens are foremost. For instance a broom finish offers more skid resistance however it will demonstrate wear much quicker than a steel troweled finish will. Whatever these conditions are should be tested if the abrasion qualities are a real concern. ASTM C-672 Scaling resistance and ASTM C-31 Compressive Strength are the two test that are all telling as to what you can expect. Can be very important! Concrete Dusting is a problem in areas where electronics attract silica dust from abraded concrete surfaces, causing problems with the electronics. Use of a product called "StableCrete" is a way to stop dusting and improve compressive strength of a concrete. This material penetrates into a concrete and forms a solid inside the capillary system of concrete making it more dense. It also waterproofs and gives acid resistance to the concrete.
How many amps does 350hp motor 480v 3 phase draw when operating?
The formula you are looking for is; Amps = HP x 746/1.73 x Volts x %eff x pf. 350 x746/1.73 x 480 x .90 x .90 = 261100/672 = 389 amps. This amperage assumes that the efficiency of the motor is at 90% and the power factor of the motor is also at 90%.
