Abstract

To study the freeze-thaw durability of different types of recycled aggregate seawater sea-sand concrete (SWSSC) in freeze-thaw dominated environments of cold regions, a compressive strength degradation prediction model [GM(1,1)] was constructed based on grey theory in this paper, and the synergistic effects of the number of freeze-thaw cycles, recycled aggregate types, and replacement rates on compressive strength were analyzed. Experimental and model prediction results indicate that the compressive strength of concrete shows a nonlinear attenuation with the increase of freeze-thaw cycles. The deterioration of recycled brick aggregate concrete is the most significant; after 75 freeze-thaw cycles, its strength is 14.50 MPa, which decreases by 57.2% compared with unfrozen concrete; after 300 freeze-thaw cycles, the strength is only 1.43 MPa, with a decrease of 90%, and the high water absorption and low crushing index of recycled brick aggregate are the main reasons. For every 20% increase in the replacement rate of recycled aggregate, the strength loss of recycled brick aggregate concrete after 75 freeze-thaw cycles increases by 22.8%; therefore, it is recommended to control its replacement rate within 20%. The prediction accuracy of the GM (1,1) model is “excellent” (p = 1, C < 0.35), with a maximum residual of 1.84 MPa and a relative error of 9.79%, which verifies the reliability of grey theory under poor information conditions. This study provides a theoretical basis for the mix proportion optimization and service life assessment of recycled aggregate concrete in freeze-thaw dominated environments of cold regions and offers an engineering reference for the resource utilization of construction waste and the substitution of river sand.
