Pumice is a type of extrusive volcanic rock, produced when lava with a very high content of water and gases is discharged from a volcano. As the gas bubbles escape, the lava becomes frothy. When this lava cools and hardens, the result is a very light rock material filled with tiny bubbles of gas.

· Pumice, also called pumice, is a lightcolored, porous vitreous rock. It is named because of its porous, light weight, loose density less than 1g/cm3, and ability to float on water. It is a kind of porous rock formed by volcanic eruption of silie magma full of gas underground.
Pumice is a natural exfoliant which is made up of volcanic ash. Pumice is formed when lava is permeated with gas bubbles during the solidifiion process. Because lava has similar properties and chemical makeup as glass, pumice is very abrasive but unlike glass, it is very soft. Pumice is the softest abrasive media in use today.
Pumice is a white, gray, pink, pale yellow or brown vesicular volcanic glass: its finergrained equivalent is pumicite or volcanic ash. Made up of small rigid bubbles, pumice has a lightweight cellular structure in which each cell is sealed off from its neighbors by a thin membrane of glass providing low permeability.

· On the other hand, limited studies have investigated the effect of grinding volcanic pumice on its properties. Some researchers have shown that grinding volcanic pumice can improve the efficiency of cement paste by increasing its activity strength index (Seraj et al. 2017 ; Zeyad et al. 2019a ) and that the use of finely crushed volcanic pumice can reduce material cost.
A cement composition comprises fine pumice particles, for use in cementing subterranean wells, and oil and gas wells in particular. The pumice containing cement blends feature enhanced compressive strength, and favorable compressive strength to Young's Modulus ratios. Lightweight cement blends containing pumice, and their use in cementing oil and gas wells are also described.
Pumicecrete. Pumicecrete is a masonry material used for building the walls of residential and commercial buildings. It is a locally produced green building material. The raw materials are found within 200 miles of Taos. Using a volcanic stone called pumice combined with Portland, cement walls are cast on the building site.

· Obsidian. Pitchstone. Pumice. Basalt or Trap. Andesite. We can list volcanic rocks that are formed at or near the surface by comparatively quick cooling of lava, cannot be classified without the aid of the microscope and chemical analysis, except roughly as lightcolored and dark lavas, conveniently called rhyolite, and basalt or trap.
· Volcanic Rocks. The majority of lavaflows are basic, that is they contain only about 40 to 50 per cent of silica; this may be contrasted with acid flows, which have 70 to 80 per cent of silica. Silica. the substance of quartz, is the common acid of minerals and rocks. Substances like lime, magnesia, potash, and soda are called bases.
Description: Pumice is a natural light weight bubbly volcanic glass essentially a "solid rock ". Being a natural product pumice contains no harmful substances, it is inert with pH of around Pumice is resistant to frost and chemicals, and will not break down in water.
