Mechanical Properties of Glubam Sheets after Artificial Accelerated Aging

Abstract:

Glubam is a kind of environmentally friendly and energy efficient composite material in civil engineering developed in recent years. But the mechanical performance after subjected aging under the outdoor conditions is a blank of research field. In this paper, a new artificial accelerated aging test method and equipment for glubam have been presented by authors. The basic material performance, including deformation changing, tensile properties, compressive properties, bending properties and internal bonding strength, are tested according to the equivalent aging duration of 120 days, 240 days, 480 days and 960 days. The failure mode of specimens shows that delamination of glubam caused by dry wet circulation is the main reason for mechanical properties degradation. All test results present monotone decreasing trend and the internal bonding strength is the most sensitive to aging duration. Aging influence factor β, internal bonding correlation coefficient η and internal correlation coefficient θ can be used to evaluate aging performance of glubam, but the accuracy of evaluation results need further research.
