Statistics indicate interesting results in terms of freezing-thawing cycle pattern in the winter season. Different types of concrete mix design have been considered and their durability against freeze-thaw cycles has been studied. Finally, a flow chart has been presented in predicting the ...
Pore-size distribution cures and bar chart of soil porosity distribution for soils at the study site in the floodplain of southwestern Shandong Province: (a) The water content is 13% and the dry density is 1.48 g cm−3, pore-size distribution curves with different F–T cycles. (b) Bar ...
regarded as the end of the freeze-thaw cycle, and the next freeze-thaw cycle is entered. Mass and elastic modulus were tested after every 25 cycles, compressive strength was tested after every 50 cycles, and pore structure was tested after every 100 cycles. The specimens were categorized based...
Fig. 6. Test flow chart. 2.2.1. Specimen freeze-thaw cycle After specimen curing, followed by immersion in water for 4 days, before the specimens were subjected to freeze-thaw testing in both water and a 5 % sodium sulfate solution. Following the rapid freezing method specified in the ...
Fig. 3. Test flow chart. 2.3.2. Fatigue and freeze-thaw test The fatigue and freeze-thaw tests of group B were carried out based on group A, which added the freeze-thaw cycles to the fatigue loading process. The number of repeated loading and unloading of the track plate is 700 thousa...

The number of strokes to the paint at which 0.5 inch of black chart shows through the test panel was recorded. Freeze-Thaw Stability Test The paint sample was transferred into a 250 ml stainless steel can and was kept in the freezer for 18 hours at -18 DEG C. Then the sample was remo...
However, the important effects of interactions between nitrogen deposition and the freeze-thaw-cycle have never been investigated. Here we show nitrogen deposition delays spikes of soil respiration and weaken soil respiration. We found the nitrogen addition, time and nitrogen addition×time exerted the...
2, Fig. 3. For NOW, the ice chart on December 19, 2016, revealed five different ice types in the region, namely: nilas, grey, grey-white (gWhite), thin first-year ice (tFYI), medium first-year ice (mFYI) and multiyear ice (MYI) (Fig. 1c). We visually inspected σHH0 ...
