Aggregates can consist of using sand, gravel, ground powder, stones, pebbles, and cement. The aggregates used will determine how strong the concrete is and what it can be used for. For instance, if you were to mix sand, gravel, and ground powder together, you would get a cement mixture that could be used to make paving tiles, but ...

Therefore, without adjusting the water consumption of concrete, the workability of concrete will inevitably be improved. In addition, the roundness is better. The high stone powder also acts as a micro-ball, reducing the friction between sand and stone, thereby improving the workability of concrete. 3. Limestone Mill
