Design Of Toughness Of Steel Fiber Reinforced Concrete

Qingdao FSS Co.,Ltd | Updated: Jan 21, 2017

Bent toughness degrees is steel fiber Jet concrete most main of performance, in design in the must has clear of provides currently domestic tunnel design specification in the on steel fiber Jet concrete of toughness degrees temporarily no provides, Japan, Korea, and the European of fiber Jet concrete specification in the, on for underground engineering in the of steel fiber Jet concrete of "bent toughness degrees coefficient (Re,3)" value most provides in 68% above. At present in the design of steel fiber sprayed concrete to tunnel engineering "bending toughness factor" value in this range.
In order to be able to easily determine whether the toughness of steel fiber sprayed concrete to meet the design requirements, specification use the "template" method in determining the sizes of steel fiber reinforced concrete specimens, providing toughness experimental curves actually curve enveloping curve above, they consider toughness of steel fiber reinforced concrete to meet the design requirements.
