Abstract

Abstract

The mix proportion of high titanium heavy slag concrete (HTHS) and normal concrete was designed. Four groups of concrete cubic and prism specimens were made and tested. Using the PFC discrete element software, the meso-structure mechanical parameters of HTHS and normal concrete specimen were calibrated. Uniaxial compressive tests of prism-shaped specimens made of HTHS and normal concrete were simulated. Furthermore, the failure phenomena and reasons of HTHS concrete prism specimens were analyzed. It is found that the strength of HTHS aggregate is decreased due to the holes within HTHS aggregate. The bonding strength of the interface transition zone between coarse aggregate and harden mortar is improved. In addition, the failure modes of HTHS and normal concrete are different. The failure surfaces of HTHS concrete pass through the coarse aggregate and hardened mortar, while the failure surfaces of normal concrete can only develop along the interface transition zone and pass through the harden mortar.
