Abstract
The article studied the effects of different dosages(0,3％,6％,9％,12％)of milling wave shaped steel fibers and melt drawn end hook shaped steel fibers on the performance of lightweight aggregate concrete.The research results show that after adding steel fibers,the compressive strength,flexural strength,elastic modulus and other properties of lightweight aggregate concrete are improved to varying degrees.However,excessive steel fiber content will lead to a decrease in its structural performance;The prepared steel fiber lightweight aggregate concrete has a flexural strength of over 8.0 MPa and a compressive strength of over 50 MPa at 28 days,indicating good application effects.关键词
