بیشترThere is a common misunderstanding that to make a finer cement you should reduce the mill ventilation to keep the cement in the mill longer. In fact, this simply leads to over-grinding and increased void filling, which reduces grinding efficiency and often leads to a wider particle side distribution, increased separator rejects and eventual reduced mill output.
بیشترThe different numbers of capillary pores in the cement stone resulted from different water-to-cement ratios of the mixture, w/c = 0.45, 0.50 and 0.55. Additionally, the number of open pores was varied by changing the post-curing conditions, i.e. the samples were stored for 24 h at different temperatures (20, 45, 80 and 105 °C).
