Yes, limestone has value as it is a common type of rock used in construction, agriculture, and industry. It is often crushed and used as a base material for roads, as a building material in construction, and for neutralizing acidic soils in agriculture. Additionally, it is a source of calcium carbonate, which is used in various industrial processes such as making cement, glass, and steel.
One common chemical test to identify limestone is the acid test. Limestone will react with hydrochloric acid to produce bubbles of carbon dioxide gas. Another test involves applying a drop of dilute hydrochloric acid to the surface of the rock; if it fizzes, then it likely contains calcium carbonate, the main component of limestone.
The melting point of limestone (calcium carbonate) is approximately 1,339 degrees Celsius (2,442 degrees Fahrenheit). At this temperature, limestone decomposes to form lime (calcium oxide) and carbon dioxide gas.
Limestone with holes is typically a result of chemical weathering. The holes are often created through the process of carbonation, where carbonic acid in rainwater reacts with the calcium carbonate in limestone to dissolve it and create cavities over time.
A good chemical test to determine the primary mineral in limestone is the acid reaction test. Limestone primarily consists of the mineral calcite, which reacts with dilute hydrochloric acid to produce bubbles of carbon dioxide gas. This effervescence confirms the presence of calcite as the primary mineral in limestone.
As weathering erodes limestone underground, it can form caves, sinkholes, and underground rivers. Over time, the chemical reactions between water and limestone can result in the dissolution and reshaping of the rock into unique structures and landscapes.
Limestone typically has a pH value of around 8-9, making it slightly alkaline. The alkalinity of limestone can help neutralize acidic soil conditions and restore balance to the pH levels in the environment.
The k0 value for limestone in the K0 procedure is used to calculate the initial stress condition upon loading. This value represents the coefficient of lateral earth pressure at rest and is typically determined through laboratory testing on limestone samples. It is an important parameter for analyzing the stress-strain behavior of soils during loading.
The friction angle of limestone can vary depending on factors such as porosity, grain size, and mineralogy. In general, the friction angle of limestone ranges from 30 to 40 degrees. This value can be used in geotechnical engineering for calculating the stability of slopes and foundations involving limestone.
concrete is formed from limestone by the combustion of the limestone (heating of the limestone)!

Limestone is called limestone because it has lime in it from the sea water it if formed in.
