Abstract

Abstract

The method of adding fiber into concrete has been commonly used in engineering to improve the crack resistance of concrete. The flake is a micron-sized material with good mechanical properties and corrosion resistance. In the paper, six groups of concrete flat plate tests, six groups of concrete flexural strength tests and six groups of acoustic emission tests were carried out by adding different contents of glass flake and basalt flake into concrete. The early crack resistance, mechanical properties after hardening, fracture process of concrete modified by flake and the change law of the development of the middle fracture were studied. The test results showed that flake could effectively reduce the early cracking area of concrete, improve the flexural strength, and mainly improve the micro-crack resistance of concrete.
