UHPC Precast Concrete under Severe Freeze-Thaw Conditions

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...

The Effects of Concrete Pavement Mix Design Parameters on Durability under Freeze and Thaw Condition

This paper is based on an experimental research that examined the effects of concrete`s major parameters on durability of concrete pavements and curbs under freezing and thawing cycles. These parameters include concrete mix design parameters such as water-cement ratio, fine aggregate percentage and using air entraining admixture and simulating real freeze-thaw cycles that infrastructures underg...

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...

Freeze-thaw decay in sedimentary rocks: a laboratory study with CT under controlled ambient conditions

This study presents an experimental X-ray micro-CT study of the freeze-thaw processes in limestone under controlled ambient conditions. The processes weres studied with time-lapse micro-CT and dynamic micro-CT, using the Environmental X-ray CT (EMCT) at the Centre for X-ray Tomography of the Ghent University (www.ugct.ugent.be). The EMCT is a gantry-based system on which full μCT scans were aqu...
