  • 2 Types of Concrete Crushers

    Abandoned concrete blocks are high-quality concrete aggregates which have many advantages. For example, after the buildings are dismantled, the high-quality concrete blocks and silt after crushing and screening can be used as recycled coarse and fine aggregates for concrete. The fine powder can be directly used as the raw material of cement. The concrete prepared from recycled cement and

  • Top Tips

    The compressive strength of a block is not directly related to its dry density. Indeed, there are a wide range of options when it comes to considering which block to use. You can get 7N/mm 2 blocks in aircrete - medium density and dense aggregate blocks for instance. When choosing the right block type to use, it’s therefore important to consider the requirements for sound insulation
