Abstract

 The carbon fiber grid bonding methods with reinforcing effects certified by the wheel load running tests conducted on ordinary RC slabs, are often adopted for anti-aging reinforcement of lightweight RC slabs using lightweight aggregates. In order to verify its applicability, the wheel load running tests were conducted for lightweight RC slabs without and with reinforced by the carbon fiber grid bonding methods. In addition to the abovementioned test results, this paper examines the reinforcing eras and effects in comparison with the fatigue damage situations of the existing lightweight RC slabs. As a conclusion, there are certain reinforcing effects of the carbon fiber grid bonding method for lightweight RC slabs, and the acquired correlation between the reinforcing eras and effects suggests that reinforcing should be implemented before crack density increases.
