A stalactite (UK: / ˈ s t æ l ə k ˌ t aɪ t /, US: / s t ə ˈ l æ k t aɪ t /; from Ancient Greek σταλακτός (stalaktós) 'dripping', from σταλάσσειν (stalássein) 'to drip') [1] is a mineral formation that hangs from the ceiling of caves, hot springs, or man-made structures such as bridges and mines.
Degrading concrete has been the focus of many studies and the most obvious sign is calcium-rich leachate seeping from a concrete structure. [5] [6] [7]Calthemite stalactites can form on concrete structures and "artificial caves" lined with concrete (e.g. mines and tunnels) significantly faster than those in limestone, marble or dolomite caves.
A speleothem (/ ˈ s p iː l i ə θ ɛ m /; from Ancient Greek σπήλαιον (spḗlaion) 'cave' and θέμα (théma) 'deposit') is a geological formation made by mineral deposits that accumulate over time in natural caves. [1]
With its spectacular stalactite formations and crystal-clear waters, this geological marvel has been sculpted by nature's hand over millions of years, creating an enchanting world beneath the surface.

A stalagmite (UK: / ˈ s t æ l ə ɡ ˌ m aɪ t /, US: / s t ə ˈ l æ ɡ m aɪ t /; from Greek σταλαγμίτης (stalagmítēs); from Ancient Greek σταλαγμίας (stalagmías) 'dropping, trickling' and -ίτης (-ítēs) 'one connected to, a member of') [1] is a type of ...
Straws (stalactite precursors) in Gardner's Gut. Soda straw. A soda straw (or simply straw) is a speleothem in the form of a hollow mineral cylindrical tube. They are also known as tubular stalactites. Soda straws grow in places where water leaches slowly through cracks in rock, such as on the roofs of caves.
This is a list of building materials. Many types of building materials are used in the construction industry to create buildings and structures . These categories of materials and products are used by architects and construction project managers to specify the materials and methods used for building projects .
Over thousands of years a stalactite forms from the ceiling as the water continues to drip. When the water drips on to the floor of the cavern some evaporation occurs here also leaving a trace of limestone. Again over thousands of years a stalagmite is formed. A stone pillar is formed when a stalagmite and stalactite meet.
