Gypsum is a very soft mineral that is easily identified by its hardness, cleavage, and solubility in water. Typically clear to white, gypsum may be colored reddish to brown or yellow if impurities are present. Most gypsum occurs in its massive form, as layers of rock that often intercalate layers of shale, limestone, or dolostone.

The rock i am crushing is lightweight ,but still is heavy compared to a pumice stone that is so porous.The thing is that due to continuous weeding,the soil on the main parts has. been degraded with no organic matter and it is exposed in the harsh sun.So i am putting this kind of rock to reflect the sun and i will throw clay seebals of cover

By definition crushed stone is a construction aggregate. It is created by mining a suitable rock formation and then breaking down the rock to varying sizes using a crusher. Crushed stone differs from gravel in that gravel has a more rounded shape and is made by the natural processes of weathering and erosion.

Gypsum, also called calcium sulphate hydrate, is a mineral found in sedimentary rock. Gypsum is formed by the evaporation and replacement of waters containing sulphates and calcium. Grey or white in colour, this amazing mineral can be crushed into fine dust and heated until most of the moisture is eliminated. This process is called calcination.

Gypsum rock is mined or quarried, crushed and ground into a fine powder. In a process called calcining, the powder is heating to approximately 350 degrees F, driving off three fourths of the chemically combined water. The calcined gypsum, or hemihydrate, becomes the base for gypsum plaster, gypsum board and other gypsum products.

Gypsum rock is usually white or colourless, although it may sometimes have grey, yellow, pink, or brown hues. Gypsum is much softer than minerals of similar colour, such as calcite or quartz, and is the only one that can be scratched with a fingernail.
