In order to investigate the steel fiber parameters on damage characteristics and crack evolution of cellular concrete materials, uniaxial compression–acoustic emission combined tests were carried out steel-fiber-reinforced (SFRCC) with different contents (0%, 0.5%, 1%, 1.5%, 2%) porosities (10% 20%). The material analyzed by acoustic IB values, types identified using Gaussian mixture clustering method (GMM) pairs. results show following: inclusion fibers increased compressive strength 19.8~46.3% at 10% porosity, 37.1~102.2% 20% porosity; addition significantly density intensity signals; decreasing tendency value peak stress slowed down increase in amount fibers, could effectively inhibit development; classification that proportion shear cracks all stages after fibers.
