Under action of repeated freeze-thaw cycles, different changes of pore structure features has occurred in different varieties of concrete.In this study, the average pore size of concrete and total porosity was discussed especially with the trends.Based on this, the gas diffusion model and the ...
This paper examines the performance of concrete beams internally reinforced with basalt fiber-reinforced polymers (BFRP) bars after being subjected to freeze-thaw (FT) cycles. Prior to beam testing, pullout specimens were tested after being exposed to 100 and 200 FT cycles and to a freezing temp...
Research on freeze-thaw resistance of concrete in general and on curing and moisture conditions in particular is motivated from an economic and product sustainability point of view. Specifically, it is argued for the importance of considering the effect of curing and test exposure conditions on the...

The effect of frost conditions on the physical and mechanical properties of geopolymer concrete (GPC) and Portland cement concrete (PCC) containing two different micro-encapsulated phase change materials (MPCM) was examined. Microstructural studies revealed that the freeze-thaw induced concrete ...
The effect of environment on FRP strengthening concrete structures is related to the bond surface of FRP and concrete. Experiments show that the bond strength between concrete and FRP sheets decreases under the freeze thaw conditions.关键词: fiber reinforced plastic (FRP bond strength freeze-thaw ...
