Guide of raw material selection for paving block machine

There is much effort to buy one paving block machine from China. But what we know is it is just the beginning. The first challenge is how to find the perfect material ratio for our paving block machine. But do not worry, here Yufeng tell you how to choose raw material. 


Two material choices for paving block machine

1. Blocks produced by soil.

Like a concrete that contains gravel, sand and cement as a binder, a soil contains gravel, sand, and, silt & clay which act as binders as well.

Soils suitable for block making require a clay content between 15-30% with the remainder being primarily sand and silt.  If a soil is too high in clay or sand, about 35-40%,  it can be amended with the addition of sand or clay respectively.  If a soil is low clay and silt, below 10%, will be difficult to handle when coming out the machine. Sometimes the soil requires screening if there is large aggregate like rocks/gravel present. Organic matter is not used for block production, so the precious topsoil can be used for growing flowers, grass, or veggies.

Water must be clean and should not contain any harmful quantities of acid, alkalis, salts,sugar or any other organic or chemical material.


2. Blocks produced by cement/concrete
