Pumice is an extrusive igneous rock with a vesicular texture and very low specific gravity. It is used to make lightweight concrete, abrasive products and more.
Pumice stone is a natural sponge-like lightweight aggregate formed during the rapid cooling and solidification of molten lava. After suitable preparation, it can be used as an aggregate to produce lightweight concrete or as a cementitious material to produce blended cement or geopolymer. This article focused on the influence of pumice powder PP on fresh properties and hardened properties of ...
Jun 15, 2015 Turkey is rich in natural pozzolan and pumice is abundantly found in several regions of the country. In this study, pumice powder PP and fly ash FA were used as cement replacement materials and the effect of partial replacement of PP, FA and their blends by cement on physical, mechanical and durability properties of concrete was investigated.

Pumice, scoria, and some expanded slags produce a concrete of intermediate strength, but with even more impressive value as insulation. Perlite, vermiculite, and diatomite produce a concrete of very low strength, but with superior insulation properties however these are subject to greater shrinkage.
Dec 14, 2013 A concrete mixing ratio of 14 will yield about 7.5 m pumice concrete for 1000 kg cement 20 bags weighing 50 kg each. The same walls with a thickness of 25 cm require 12.5 m pumice concrete. For a mixing ratio of 14, about 1750 kg cement 35 bags weighting 50 kg each are needed for 12.5 m pumice concrete.
Pumice and Roman Concrete. Some two thousand years after the Romans built it, the dome of the Pantheon is still the worlds largest unreinforced concrete dome. The concrete mix design Roman engineers figured out stands as a historically impressive architectural feat. Their empiretemples, roads, aqueducts, piers, arenaswas built from this ...

Concrete block produced with Mountain Pumice Lite-Rock has significant advantages over comparable concrete block made with heavier traditional weight aggregates. For example, an 8 x 8 x 16 concrete block made with Lite-Rock is approximately five pounds lighter than a counterpart made with limestone or gravel.
Pumice Concrete Products. BLOCKS, SUMPS amp EMPLACED CONCRETE. Atiamuri pumice is characterized by its relatively light weight, and hardness making it extremely desirable for use in concrete applications.. Block Manufacture. Both our 1-7mm and 0 -10mm pumice are used in the manufacture of concrete blocksThe addition of pumice in block manufacture allows for a product
Pumice Aggregate is seen as a preferred choice to other materials due to its weight, where the pumice is a third lighter than other materials.When the pumice is used in a concrete mix, it increases the elasticity of the product, providing a more flexible compound, this is beneficial for high rise buildings which have to cope with additional ...
A pumice stone is an exfoliating tool used to gently remove calluses and dead skin from feet, hands, knees, and elbows. Natural pumice stone is a type of volcanic rock that trapped small gas bubbles inside while it cooled. This is what causes the pumice stones rough, pocketed exterior, it is also what makes it an effective exfoliant.
Pumice concrete, or even the dry pumice alone, is used as an insulating cavity fill for concrete block walls. pumice pozz vs. fly ash . A two-year University of Texas-Austin study done for the Texas DOT compares the perfomance of pumice pozzolan with Class F fly ash in concrete over a two-year period.
Its important to understand that Pumice-Crete is not a replacement for ordinary concrete in load-bearing footings, retaining walls, flatwork and other common uses, but rather is an economical, highly-insulative, cast-in-place wall system that stands as a cost-effective, efficient and performance-enhanced alternative to typical stick-built ...
Pumice concrete is composed of Portland Cement, pumice aggregate, pumice sand, pumice pozzolan, and water. Compared to regular concrete, pumice concrete offers roughly a one-third reduction in weight. Proportioning, mixing and placing are done in a similar manner to that of conventional concrete, as is the finishing. The applications for pumice ...
