reinforced the concrete.While polymeric FRC shows spalling resistance at fire,however,its post fire residual mechanical properties is of great concern,as these fibres are melt at elevated temperatures or lose their properties significantly if not melted.In addition to polymeric fibres,steel fibres are also widely used to reinforce concrete. What's the allowable leak rate for a concrete tank?What's the allowable leak rate for a concrete tank?Measurable flow in this area is not permissible and must be corrected.Per AWWA,the allowable leakage rate is 0.1 percent of the water volume in 24 hour.You can always specify higher requirements than the minimum standards.Concrete Tank Leak Test - Civil/Environmental engineering What's the difference between AF and VF in reinforced concrete?What's the difference between AF and VF in reinforced concrete?Af is area of fibers and Vf is volume fraction of fibers.In the analysis of reinforced fibrous concrete,each fiber is considered as small longitudinal reinforcement present through the whole length of section.The ultimate tensile strength of fiber reinforced concrete is calculated by using the following equation:Fiber Reinforced Concrete - an overview ScienceDirect Topics
