2021-2-11 · THE PROBLEM: Cement dust is so fine that it can pass through a sieve that can hold water. This fugitive dust builds up and hardens in areas around finish mills and clinker storage, wreaking havoc on conveyor systems. Additionally, product spillage throughout the process results in costly product loss and requires hundreds of man-hours for clean-up.

Enhancing the hydrophobic PP fiber/cement matrix

The microstructure of the fiber/cement interface before and after the test were examined, as shown in Fig. 11, Fig. 12, respectively. Fig. 11 compares the PP/cement interface and the PP-O-Al/cement interface before the test. Although the interfaces look very similar at a low magnification (1000 × ), PP-O-Al/cement interface apparently shows a ...
