What Is Limestone? How Is Limestone Made?

Planet Earth is one of the rocky planets because the crust is mainly composed of rocks, rocks composed of the crust are three types: igneous rocks, which resulted from volcanic activities, and metamorphic, which formed by exposure Other rock types of pressure and temperature extreme in the ground, which in turn led to a transformation and, finally, there are sedimentary rocks that resulted from an exposed rock gestures intense pressure and heat, which in turn led to the cohesion and the formation of sedimentary rocks, sedimentary rocks are most prevalent on the Earth's surface rocks.

The three types of rocks that cover the Earth's crust, has taken advantage of these rocks in many things, especially in construction, such as: the use of some types of igneous rocks in paving streets and gardens in construction as granite used in kitchens, and could also burn these rocks and rock wool production which is used in insulation of buildings, use some types of shale also in construction, such as marble, but the main rocks used in construction are sedimentary rocks.

The fact that sedimentary rocks form the highest percentage among the three rocks in the presence on the ground has been used extensively in construction, especially limestone or what is sometimes called the limestone, which is abundant in Jordan and the finest types of so-called rock sheen, which issued Jordan him large amounts to other countries, limestone, used mainly for the production of so-called lime, lime, what is?.

 For the definition of lime scientifically it: lime is calcium oxide is produced from the burning of limestone on the steps of a very high temperature ranging from 900 - 1300 ° C, and vary lime properties by limestone burned and its characteristics and attributes of the type, and the lime product may be sold and is used as is or be cut to small parts, or grinding powder and work from it, depending on the requirements of use.

 The lime industry and its uses have been known since time immemorial in the ancient human civilizations, it has been used by the Pharaohs and the Greeks and Romans produced from concrete material used in construction.
