PUMICE IN ENGINEERED SOILS. Interior concrete block walls Pumice has a nature-blessed and unique structure—essentially a foamed stone. Large precast retaining wall blocks That sponge-like texture works wonders when added to native soils. Polished concrete walls perth It’s lightweight, for one, lightening the load for soils blended for applications like green roofs and raised planter boxes.

Precast concrete panels india It alters the functional structure of the soil, for another. Concrete foundation wall crack repair It is especially effective in poor native soils, shifting the structure and tilth to “air-out” the root zone to better support plant life. Painting concrete block interior walls Pumice also retains moisture and nutrients in its frothy matrix, giving ’em back to roots over time. Precast concrete walls for a house for sale Pumice-blended soils also absorb and drain water efficiently. Insulated precast concrete wall panels The aggressive filtering character of pumice also means it grabs and hold run-off borne contaminates that would otherwise foul steams and lakes.

Pumice does naturally what manufactured, heat-expanded soil-conditioning products like perlite and expanded clays do, for less cost. Concrete retaining wall design software Expansive engineered soil structures like ecology embankments, wetlands, rain-wicking paver bases, bioretention basins, and high-traffic turf areas all benefit from a cost-effective percentage of pumice in the soil.?

PUMICE IS A LIGHTWEIGHT AGGREGATE. Finishing exterior concrete walls Pumice is stone—a light, frothy stone, riven with thin-walled pockets of air. Sandblasting concrete walls The hard-yet-light character of pumice makes it popular as a cost-efficient lightweight aggregate. Types of concrete retaining walls Primary, it is mixed with cement to produce a lightweight, insulating concrete.

Precast concrete applications—manufactured stone veneers, statuary, fences and sound walls, tilt-up wall panels, blocks, and bridge sections—all face the expense of shipping. Diy poured concrete retaining wall The more things weigh, the more they cost to ship. Concrete retaining wall diy The perfect balance of lightweight aggregate and functional strength are the answer. Precast concrete basement wall panels And in the case of precast concrete construction materials—lightweight means less wear and tear on equipment and construction workers. Polished concrete walls the block It can even mean less mass needed in support footings and structural supports. Latex paint on concrete basement walls It all adds up money saved.

Pumice aggregate is also used as a lightweight fill behind bridge abutments and and other engineered structures where excessive weight is a long-term concern. Concrete basement wall crack leak repair It compacts well and readily mixes with fines and other binders.?

PUMICE AS AN POLISHING TUMBLING MEDIA. Sealing interior concrete walls The quickest way to a smooth finish and high shine for small parts is an ultrafine polishing media. Poured concrete house walls Pumice has an amorphous structure, so even when crushed to fine powder grades, it holds its sharp, glassy edges. Concrete foundation wall design example Nor does it “round off” during use, losing its tooth: even as it breaks down during use, it continues to gently abrade and polish. Insulation against concrete walls basement Pumice is used to tumble a glossy shine on small plastic and metal parts, like buttons. Poured concrete retaining wall forms Larger pumice stones are tumbled with stiff fabrics like denim to soften and condition. Poured concrete retaining wall vs block Microfine pumice is also used as a polishing grit in rubbing compounds.?

foamed glass, formed by the expansion of trapped gases when molten lava rapidly cools. Concrete retaining wall thickness When crushed, pumice still retains its frothy structure, making it effective at any filtration grade. Precast concrete panels for homes Pumice is an aggressively-filtering alternative to sand (and other filtration media) for the treatment of municipal and industrial effluents. Diy concrete retaining wall The low specific gravity and high porosity of pumice make it ideal for these applications and treatment processes.

Pumice is also used in biological scrubbers that remove the nasty stuff from wastewater and industrial emission gases—H2S, mercaptans, and VOCs.

And when it comes to beverage filtration, the same characteristics that make pumice a superior filtration media for water also hold true for cooking oils, beverages and other liquids. Off form concrete walls Pumice is non-toxic, completely inert and extremely versatile—it can be processed consistently to a wide range of specs.

Pumice is even added to engineered soils that are used in constructing ecology projects that are designed to filter wastewater, storm water, mine drainage and agricultural runoff before entering steams and lakes.?

PUMICE AS A FUNCTIONAL FILLER/EXTENDER. Prefab concrete walls house Pumice is amorphous by nature, meaning it has a no crystalline structure, meaning no breathing hazard when handling during manufacture. Precast concrete walls Finely-graded pumice powders are excellent for use as functional fillers and extenders for such things as paints and other coatings, rubbers, and plastics. Finishing poured concrete basement walls When used in paints and coatings, pumice is hard enough to provide outstanding scrub, burnish and stain resistance properties. How to build concrete shower walls Hiding power is also improved. Poured concrete retaining wall thickness In general, pumice NCS (non-crystalline silica) powders are safe, viable, high-performance substitutes for crystalline silicas and zeospheres fillers. Insulated tilt wall panels A bright white pumice powder, like that from the Hess deposit, means colors remain rich and vibrant.?

PUMICE-CRETE STRUCTURES. Precast concrete panels residential homes Although concrete is an incredibly versatile construction material, it’s primarily known for its heavy-duty, cold-grey utilitarian role.

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. Pouring a concrete wall The Pumice-Crete mixture is cast into place using lightweight formwork, typically at a thickness of 18-24 inches and finished with a quality cementitious plaster (like LimeStrong plaster) inside and out, further enhancing the thermal performance of the thick honeycomb-like wall.

Pumice-Crete walls are fireproof, noise-dampening, and economical in terms of placing and sourcing the material.

As the walls take on the look of the shaping forms, a wide range of architectural expressions are possible.

It’s 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 construction. Precast retaining wall cost ?

HORTICULTURAL PUMICE. Pouring concrete basement floor cost Pumice makes a great in-soil conditioner. Insulated concrete forms basement walls Mixed with poor soils (like heavy clay soils), pumice will significantly improve the soil profile and tilth by opening up the root zone, holding moisture and nutrients in its maze of nooks and crannies, and facilitating drainage. Forming concrete walls snap ties Pumice is readily mixed with compost, remaining permanently in the soil to condition and amend structure long after the organic compost components are consumed.

Of particular interest is a study by the University of Illinois’ Department of Horticulture that found pumice to be the physiochemical twin to perlite. Poured concrete wall crack repair Meaning pumice is the equivalent of perlite in beneficial behavior and performance when utilized as a soil amendment. Pouring concrete walls for basement Perlite is a well-understood and widely-used, especially in potting soil mixes. Architectural concrete walls But perlite ore must be superheated and “popped” to attain its beneficial properties. Solid concrete walls Pumice was naturally calcined by volcanic action, so needs only to be crushed to grade, making it an economical alternative to perlite (and other soil amendment products made from expanded clays). Concrete retaining wall design example That’s especially welcome in large scale in-soil or soilless applications. Painting unfinished basement concrete walls Also, pumice is denser than perlite and stays blended in the soil instead of “floating” out.?

CIRCUIT BOARD POLISHING/PREP. Poured in place concrete wall cap The pre-cleaning process of a printed circuit board (PCB)—and in particular its copper components—is key to establishing optimum conditions for the application of films and solder masks. Precast concrete retaining walls brisbane Pumice-slurry scrubs are process-mature, cost effective, and widely applicable.
