چکیده انگلیسی
This paper studied the fabrication and properties, including strength, water absorption, resistance to sulfate attack and chloride ion penetration, and micro-structure of a new type of mortar made with recycled clay brick (CB) and post-consumer polyethylene terephthalate (PET). The effects of binder to CB aggregate ratio and curing condition on strength were investigated. The results indicate that binder to CB aggregate ratio had a significant influence on strength. The optimum value was 1:2. For curing condition, specimen cured at 180 °C for 2 h had higher strength. The specimen with proper mix proportion and curing could reach 42.5 MPa and 12.6 MPa for compressive and flexural strength, respectively. Also, the 4-h compressive strength was 85.4% of 28-day strength. The PET mortar had low water absorption of 0.87% and high resistance to sulfate attack and chloride ion penetration. Scanning electron microscope (SEM) test showed that PET mortar had uniform micro-structure with very low porosity. The CB aggregate was well covered by PET. There were no micro-cracks found in the aggregate-paste interfacial area.
