Abstract: The purpose of this study is to investigate the performance of fiber reinforced concrete to protect people or assets in buildings from explosion or debris missiles. Compared with ordinary ready mixed concrete system, fiber reinforced concrete is difficult to be applied under actual construction conditions. The fibers used for protective properties need high toughness to withstand the huge energy generated by explosion, but a large number of fibers are required. Insufficient dispersion and processability of the required fibers will reduce the processability of the fibers. In the ready mixed concrete system of factory mixing, conveying and pouring, it has been difficult to pour fiber-reinforced concrete in situ. In this study, the performance was studiedof combined fiber of steel and polymeric fiber to improve workability and agitating in the mixer. Based on the preliminary experimental test results in a laboratory, combined fiber-reinforced concrete was applied on the actual field construction of chemical plant. According to the results from the laboratory tests and application in the real construction project, it is expected to introduce the combined fiber for desirable mechanical performance with less adverse effect on workability of the mixture.
