A brick is building material used to make walls, pavements and other elements in masonry construction. Traditionally, the term brick referred to a unit composed of clay, but it is now used to denote any rectangular units laid in mortar. A brick can be composed of clay-bearing soil, sand, and lime, or concrete materials. Bricks are produced in numerous classes, types, materials, and sizes which vary with region and time period, and are produced in bulk quantities. Two basic categories of bricks are fired and non-fired bricks.

From the above table, it can be clearly seen that the plasticity index, dryness sensitivity index, and dry linear shrinkage of the mixture tend to increase with the increase of the particle composition below 0.5 mm in the mixture.This fully shows that the use of geotechnical test method can not fully evaluate the properties of plastic materials such as shale and coal gangue that rely on reducing particle size.From the above analysis, the plasticity degree has a great relationship with the particle size of clay minerals.

For example, assuming that the type and total amount of clay minerals contained in a kind of clay are exactly the same as that in a certain type of shale, plasticity index measured by the geotechnical test method is much higher than shale,because  dispersed clay mineral particles in the clay are uniform and small.If the shale is fully crushed, so that the clay minerals in the shale reach a finely dispersed state like the clay mineral particles contained in the clay, it is possible that the plasticity index measured by the geotechnical test method will be the same as that of the clay.However, it can’t be achieved in actual production,causing a great plasticity fluctuation during processing raw materials such as coal gangue and shale.Which method should be used to describe and compare the plasticity of these raw materials?
