Durability of Structural Recycled Aggregate Concrete Subjected to Freeze-Thaw Cycles

Freeze-Thaw Durability of Air-Entrained Concrete

One of the most damaging actions affecting concrete is the abrupt temperature change (freeze-thaw cycles). The types of deterioration of concrete structures by cyclic freeze-thaw can be largely classified into surface scaling (characterized by the weight loss) and internal crack growth (characterized by the loss of dynamic modulus of elasticity). The present study explored the durability of con...

Performance of Glass Concrete Subjected to Freeze-Thaw Cycling

This article reports the potential use of waste glass powder (GP) to improve the performance of concrete subjected to freeze-thaw (FT) cycling. Three GP contents were utilized in the study: 6%, 12%, and 18% by weight of cement. The other experimental parameters that were investigated in the study include: water to cement ratio (0.4 and 0.6) and aggregate type (limestone and tuff). Concrete pris...

Compressive Strength Study on the Freeze-thaw Resistance of Recycled Aggregate Concrete Members

Results: The experiment results indicate that the type of recycled aggregate and its replacement ratio have significant effects on the freezethaw performance. The cubic compressive strength of recycled aggregate concrete is overall slightly lower than that of normal concrete. After 100 freeze-thaw cycles, the compressive strength decreases and the reduction extent increases with increasing repl...

Model uncertainty of recycled aggregate concrete beams subjected to bending

This paper investigates whether the model uncertainty of reinforced recycled aggregate concrete (RAC) beams subjected to bending differs from that of reinforced natural aggregate concrete (NAC) beams. An introductory remark concerning the importance of the codification of RAC structural design is made and notions concerning model uncertainties and their role on structural codification are given...
