PRODUCTIVITY RATES. Ideally, concrete masonry productivity rates should be compiled by masonry estimators, based on records of completed jobs. Published productivity rates, such as those shown in Figure 1 and Table 1, should be used as guidelines only. The following sections discuss some of the various factors that can impact masonry productivity.

Cement grinding. The feed for a cement grinding unit will normally be dry and. needs to be ground to a high degree of fineness. To achieve this efficiently, most mills will be split into two chambers. The first is set up for coarse grinding with a target to grind the feed materials down to around 1 mm. We recommend installing a step
