Our concrete pulverizers are machines that crushes demolished material between one fixed and one moving jaw to reduce the particle size and to separate iron from other material. We have two main categories of pulverizers the bulk pulverizers and the demolition pulverizers.
Before the concrete is scooped into the moulds, the moulds must be lightly coated in a mould release agent. This ensures that the concrete does not stick to the mould and makes it easier to remove the cube. When using a 150mm mould, the concrete sample is scooped into the mould in 3 equal layers (50mm) and compacted between each layer.
Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill.
