Q: How to build a fine stone concrete cushion?: The main role of the cushion is to meet the requirements of the design elevation. In addition, the cushion to meet the sound insulation, insulation, insulation, slope and buried pipeline and other functional requirements and set a variety of levels.

Q: Why calculate the amount of time to count a lot of cushion ah: It can be seen, in the preparation of the project budget, the cushion is also a very important sub-head, the amount of its calculation is often measured by m3, the current commonly used materials are concrete, gravel, stone, Stone slag), slag, slag concrete, lime and so on.
