Change Trend

The mechanical strength change trend of Portland cement at different temperatures (+5°C, 0°C,-5°C,-10°C) was researched, and hydration performance and slurry structure of Portland cement was studied. Results showed that hydration process of Portland cement didn't vary with the lowering of curing temperature, but each stage of hydration time extended. The temperature decrease prolonged formation time of hydration products, making the early microstructure to loose, produces more pores, and causes the early mechanical strength of Portland cement to decrease.

Anammox Granular Sludge

The start-up of the first full scale Anammox reactor is complete. The reactor shows stable operation, even at loading rates of 10 kg N/m3.d. This performance is the result of the formation of Anammox granules, which have a high density and settling velocities exceeding 100 m/h. With this performance, the Anammox granular sludge technology has been proven on full scale.
