Abstract

In China, more than 1.7 billion tons of construction wastes are generated each year due to the demolition of old buildings. The main reason for the rapid growth of construction wastes is that the existing demolition methods focus on efficient demolition or directional collapse, without considering the retention of the mechanical performances of concrete materials or components. Therefore, the reuse of the main load-bearing components as the recyclable concrete materials in old buildings has become a key issue. Fracture surface morphology of the recycled concrete brings significant effects on the connection performances of the recycled concrete components. Towards improving the reusability of the recycled concrete, this work presents a high-pressure abrasive water jet method to demolish old buildings. A simple method to quantitatively calculate the fracture surface roughness in macro-level based on three-dimensional (3D) scanning was proposed, the fracture surface morphology of the recycled concrete under water jet impact was analyzed. Furthermore, scanning electron microscope was employed to observe the microscopic characteristics of the adhesion of cement onto aggregates in micro-level. Results show the fracture surface texture depth of the non-treated concrete ranged from 0 to 4.0 mm based on 3D scanning. Accelerated aging could promote the removal efficiency of concrete, by increasing the texture depth by 0.5 to 1.0 mm under water jet impact. Based on the reconstructed 3D scanning data, the calculated fracture surface roughness of the non-treated concrete was between 1.11 and 1.19, and the roughness of accelerated aged concrete generally increased by 4.0% to 14.9%. Failure mechanisms of concrete under water jet impact mainly involved compressive shearing failure and tensile shearing failure. Fracture surfaces of concrete by water jet impact could be roughly divided to be the smooth region, the transition region and the tearing region. Research results can provide guidelines for process optimization of old building demolition by water jet.
