![]() The utility of coarse-grained materials for roads can be improved by the addition of a small amount of clay to act as a binder for the sand and gravel particles. Moreover, serious frost heaving in well graded sands and gravels can be caused by fines making up less than 10 percent of the total soil weight. Chemical reaction may take place when the refractory comes in contact with fuel ashes, slag, gases inside the furnace, and the products such as glass or steel. ![]() However, fire clay bricks are generally placed in the neutral group. Silica is decided to be acidic and magnesia bricks are strongly basic. If as little as 10 percent of the particles in sand and gravel are smaller than the No.200 sieve size, the soil can be virtually impervious, especially when the coarse grains are well graded. Silt and Clay are considered to be smaller family members of soil group, Even small amounts of fines can have significant effects on the engineering properties of soils.
