Abstract:

Sixteen controlled low-strength material (CLSM) mixtures with various cement-to-sand (C/Sa) ratios and water-to-solid (W/So) ratios were prepared using recycled fine aggregate from urban red brick based construction waste. The fluidity and bleeding of the fresh CLSM mixtures were measured via the modified test methods, and the hardened CLSM mixtures were then molded to evaluate their compressive strength and durability. The results show that the fluidity of the fresh CLSM mixtures is 105 to 227 mm with the corresponding bleeding rate of 3.7% to 15.5%, which increases with the increase in fluidity. After aging for 28 d, the compressive strength of the hardened CLSM mixtures reaches 1.15 to 13.96 MPa, and their strength can be further enhanced with longer curing ages. Additionally, the strength increases with the increase of the C/Sa ratio, and decreases with the increase of the W/So ratio under the same curing age. Based on the obtained compressive strength, a fitting model for accurately predicting the compressive strength of the CLSM mixtures was established, which takes into account the above two independent variables (C/Sa and W/So ratios). Moreover, the durability of the hardened CLSM mixtures is enhanced for samples with higher C/Sa ratios. © 2017, Editorial Department of Journal of Southeast University. All right reserved.
