Pumice is an ideal soil conditioner for greenhouse applications demanding a long-lived, hard-working propagation and growing medium. The high-performance concrete needed to cement high pressure and high temperature oil wells must be flexible, enduring, and very strong.
The construction industry uses pumice pozzolan enhanced concrete to add durability, longevity and strength to critical concrete applications—roads, bridges, precast concrete products, GFRCs, well cements, cementitious grouts, lightweight tilt-up panels, and decorative concrete.
The pumice provides both in-built insulation and a 40% weight reduction compared to standard precast concrete. The product can be used in both residential and commercial construction. We don't get involved in building ourselves; we simply manufacture and supply the panels to architects' and engineers' designs and deliver them to site.
Oct 19, 2017· Pumice concrete block products are most popular in Mid East, Africa, and Domestic Market. You can ensure product safety by selecting from certified suppliers, including 65 with ISO9001, 64 with OHSAS18001, and 64 with ISO14001 certification.
Pumice as a concrete pozzolan is nothing new—the Romans were using naturally calcined pumice (they first sourced pumice from Pozzuoli in Italy, which subsequently became the origin of the term "pozzolan") in their concrete infrastructure 2000 years ago.
Development of lightweight pumice concrete with a 28-day strength greater than 3500 psi (24133 kPa) may significantly increase the use of concrete in residential construction. Precast panels made from this concrete were used extensively in the Rockwood residence on Hayden Island, Portland, Ore.
What is Pumice? Pumice is a light-colored, extremely porous igneous rock that forms during explosive volcanic eruptions.It is used as aggregate in lightweight concrete, as landscaping aggregate, and as an abrasive in a variety of industrial and consumer products.
Formulas for Lightweight Concrete. Fernando Martinez Lewels has a M.S.C.E degree from the University of Texas at El Paso. He is now working with the Agartif company in Chihuahua, Mexico (about 170 miles from El Paso Texas).
GFRC Panels and Products. Glass fiber reinforced concrete (GFRC) products apply lightweight mold-cast concrete on a grand scale, resulting in panels that beautifully skin and protect large structures and finish interior walls and ceilings with fascinating, enduring detail.
Pumice, scoria, and conventional concrete mixes were all used in construction of the award-winning Rockwood residence in Portland, Oregon. Expanses of glass figure prominently in the contemporary home, which has all its load-bearing wall panels made of pumice concrete.

Hess pumice concrete has 4 times the R-value of typical sand-and-gravel aggregate concrete. This significant R-value increase both slows heat transfer and eliminates or reduces moisture condensation on walls and ceilings.
Once the pumice-concrete mixture consisting of pumice, cement and water has been properly prepared, it can be poured into various molds to produce different kinds of wall members, e.g. pumice-concrete tiles/ panels and reinforced pumice-concrete hollow-core planks (cf. Fig. 22).
Pumice: The Ideal Microbead Replacement Hess Pumice has been used for years in a variety of exfoliating and cleaning products—shower and body gels, facial and foot scrubs, heavy duty hand cleansers, and cleansers for kitchen and bath surfaces.
We manufacture expanded perlite for filtration, cryogenic, horticultural and industrial applications and vermiculite for industrial and horticultural applications.. We operate sand, pumice and perlite quarries. The business is a privately owned, family managed entity.
Pumice aggregates and pumice pozzolan are used extensively in the production of stone and brick veneer products, glass fiber reinforced panels, architectural elements, statuary, and other precast concrete products. Pumice makes the ideal aggregate: it can be economically sized for any needed mold shape, provides bulk and strength yet results in ...
Lightweight Concrete Aggregate. Garibaldi Pumice produces a lightweight aggregate for concrete products. Use of dacite pumice reduces the weight of concrete products without substantially compromising strength.
