Pumice-Crete® is a low density, lightweight, low-rise structural concrete using 3/8 pumice aggregate, Portland cement, and water. The honeycomb-like walls are formed and poured at a typical thickness of 18-24 inches, with no additional structural reinforcement or insulation needed. Wall surfaces are finished inside and out with plaster (a pozzolan lime plaster is ideal), further improving the thermal
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 a lightweight product that can be used as interior
Jan 01, 2003· The main results at the actual stage of this research are presented through the paper. Specifically, the results of the tests on lightweight pumice stone concrete (LWPSC) wall panels subjected to vertical and lateral loads are shown and compared to those obtained from similar NWC and lightweight expanded clay concrete (LWECC) wall panels. 2. Pumice as an aggregate for structural lightweight concrete. Pumice
Pumice, the result of volcanic activity, has been used successfully, economically, and extensively as a lightweight concrete aggregate for two millennia, most famously by the Romans. The use of man-made and function-enhanced lightweight aggregate is a modern development striving to provide the same mechanical and physical benefits of pumiceyet pumice remains the most widely used aggregate for lightweight concretes.
Then the results of an experimental investigation are described, in order to show that pumice can really be considered an alternative to common artificial lightweight aggregates, taking into account the performance pointed out by loading tests carried out on structural systems made of LWPSC. Three different kinds of reinforced wall panels were made using LWPSC, lightweight expanded clay concrete and normal weight concrete
PUMICE CONCRETE is composed of Portland cement, pumice stones, pumice sand, pumice powder (pozzolan), and water. Compared to standard concrete, pumice concrete offers roughly a one-third reduction in weight and four times the r-value.
Lightweight Concrete Aggregate: Lightweight pumice aggregate for craft-type precast concrete projectsincluding statuary, containers, paverswhere a smaller aggregate size (3/8 to 1/8-inch stones with some fines/sand) is desirable. Lightweight Pumice Sand: Pumice sand + (includes) tiny 1/8-inch stones. Use in lighweight mortars and as an additive to the craft aggregate when more sand

Litecrete lightweight precast concrete is manufactured using local pumice aggregate. 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 dont get involved in building ourselves; we simply manufacture and supply the panels to architects and engineers
Concrete Leveler achieves high 24-hour strength and can be covered with finished flooring in 4 to 16 hours at 70 Degree F (21 Degree C), depending on the flooring type. It can be used indoors and outdoors. More + Product Details Close. Products shown as available are normally stocked but inventory levels cannot be guaranteed.
Pumice concrete is molded and formed into statuary, ornate exterior furniture, counter tops, fence panels, fireplace surrounds and more. It is the perfect choice for casting cornices, columns, copings and other architectural elements (especially in restoration work).
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.
Pumice concrete blocks, which are used in Interior Anatolian Region of Turkey, can be classified in the second category.
utilisation of saturated pumice as an internal curing media for high performance concretes and thin concrete sections, which are both typically prone to significant shrinkage problems. PUMICE AGGREGATES The name Pumice is a generic term for a range of porous vesicular materials produced during explosive volcanic eruptions.
Pumice-Crete® is an innovative construction concept that combines the aggregate-binding properties of Portland cement with the lightweight foamed-stone characteristics of pumice aggregate to create a unique structural wall material with impressive insulative properties.
Wall and floor panels Sandwich panels with a layer of Pumice concrete walls and scoria concrete floors are fully load bearing in this residence on Portlands Hayden Island. It is believed to be Oregons first successful structural use of pumice concrete. Pumice and scoria concrete panels for Oregon home Making the wall panels for the Rockwood residence.
Nov 23, 2013· For poring the panels, prepare a soil-moist pumice-gravel concrete, consisting of four parts pumice gravel to one part cement, and fill the wooden frame with it as described in Chapter 3.2.1. Place the reinforcing lattice such that it floats at the centre of the panel; smooth the surface of the panel with a strike board or trowel (Figs. 38c and 38d).
These innovative concrete panels are lightweight, versatile, and easy to install thanks to their patented design and ultra-thin profile. Concreate® for Trueform Concrete Trueform Concrete is an authorized distributor of Concreate® Wall Panels. Concreate® Panels offer all the aesthetic benefits of traditional concrete and GFRC panels - but at

Prestressed concrete wall panels, are a versatile product which can be used to store and retain a wide variety of materials. Installation of the concrete panels is quick and easy, the elements can either be positioned into the web of a steel column, or clipped to the outside face.
Pumice concrete for structural wall panels
Pumice pozzolan is not cementitious by nature, but when used as a replacement for a percentage of the Portland cement (up to 40%), it fuels a powerful pozzolanic reaction that works at the molecular level within the concrete paste to create additional C-S-H from Calcium Hydroxide (CH).*.
The structural use of pumice as a natural light inert for lightweight concrete has already been studied by Failla et al. 1982 4 , Mancuso et al. 1983 5 , Arici and Miraglia 1989 6 ,
May 09, 2018· Lightweight concrete may not be as structurally sound as traditional concrete, but it can be useful in some projects where weight is more important than strength. To make this concrete, combine 8 parts cement, sand and lightweight aggregate with 5 parts water.
