concrete structure comprising conventional concrete and steel fibers to reinforce concrete

摘要

Great elongation fiber with good anchorage The present refers to a steel fiber for reinforcing concrete or mortar. The fiber has an intermediate part and anchor ends. the intermediate part has a maximum load capacity fm and has a widening at maximum load ag + and · the widening at maximum load ag + and is at least 2.5%. the steel fiber has an anchoring force on said concrete or said mortar of at least 90% of said maximum load capacity fm. the anchor force is the maximum load obtained during a start strength test of a steel fiber embedded with one of said anchor ends in said concrete or said mortar. Steel fiber has the advantage that it can be used at normal dosages in concrete-bearing structures.
