Standard Mix. The nominal concrete mix of a fixed proportion of cement, sand and aggregate provide considerable variation in strength resulting in the poor or over-rich mix. Hence minimum compressive strength has been assigned in many proportions and termed as the standard mix. As per IS 456:2000 Standard Concrete grades are M 25, M 30, M 35, M ...

It was noticed that the use of copper slag as fine aggregate could greatly increase the abrasion resistance of the cement mortar (Tang et al., 2000). Hwang and Laiw (1989) evaluated the compressive strength development of mortars and concrete containing fine copper slag aggregate with different water to cement ratios (Fig. 4, Fig. 5).

Because the gravel holds and releases heat, the layer of gravel on a BUR flat roof can both help water evaporate and keep heat away from the underlying roof structure. The gravel provides a better grip for foot traffic when conducting maintenance or repairs. The gravel also acts as a protective measure to prevent natural debris (such as leaves ...
