ROBO sand: ROBO sand or crusher dust obtained from local granite crushers was used in concrete to cast the cubes and cylinders. The bulk density of ROBO sand or crusher dust is 1768 kg/m3. The specific gravity and fineness modulus of ROBO sand are 2.66 and 2.88 respectively. Sieve analysis results are shown in Fig. No. 2
Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed.
Jun 18, 2018 · I’ve used bagged concrete for years and had great success with it. My two most recent uses were for the in-ground piers that support a massive deck and the piers for my giant two-story shed.
Apr 14, 2020 · The mixed sand fineness modulus is not less than 1.8, and the ultra-fine sand fineness modulus is not less than 0.9.
