Experimental And Applied Research Of Fiber Reinforced Concrete On The Urgent Repair Of Airfield Road-Surface

With the fast development of our national economy, the quantity of the civil plane and density of flight increase by a large margin , the load of the airfield runway increase severely , cause a large amount of damage in case of far lower than life expectancy of a surface of various kinds of concrete. The fracture phenomenon in various degree take place in a large number of faces of Capital International Airport of Beijing, mend result to be relatively bad with concrete , use short time must will be mended again. So we think among concrete adding fiber, improve various kinds of performances and qualities of concrete, thus may solve the problem. This text ,we mainly do experiments on the double-deck Steel fiber reinforced concrete and Polyacrylonitrile fiber reinforced concrete under the normal atmospheric temperature, to test many kinds of performances and qualities, such as the compressive strength,the flexural strength,the splitting tensile strength,the resisting flexural strike performance,the preventing crack performance in early days. Through the comparison and analysis that are tested , choose a kind of relatively excellent fiber reinforced concrete schemes, confirm the rational construction craft. Then pave the experimental highway section in the Capital Airport to validate the practicability and feasibility of laboratory conclusion. Finally, carry on economic worth analysis and social effect appraisal, make objective appraisal to application prospect of fiber reinforced concrete on airfield road-surface. My research result indicate: the double-deck Steel reinforced fiber concrete and Polyacrylonitrile fiber reinforced concrete can both improve many performances of concrete similarly. But the resisting flexural strike performance and the preventing crack performance on early days of Polyacrylonitrile fiber reinforced concrete are more ascendant, therefore we adopt this project to mend and achieve satisfactory effect. It can also bring to us definite economic and social benefit if we build airfield road with it. This adequately testify the widest applied foreground of fiber reinforced concrete on airfield road-surface.
