When using Fibre concrete block spacers machine to produce concrete cover block, many people will pay attention to the proportion of raw material, actually this kind of practice is correct, the raw material of scientific mix proportion is the foundation that produces high grade concrete cover block, actually the factor that affects concrete cover block quality has a lot of, besides the proportion of raw material still is concerned with adding water. If the mixing ratio of raw water in the production of Fibre concrete block spacers machine is more than that of water, the raw material will be bonded in the mould of Fibre concrete block spacers machine and cannot be removed from the mould. If water is added less, the raw material will not be formed.
