Lightweight Pumice Aggregate for Craft Concrete applications. Lightweight Pumice Sand Plus. 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 onethird reduction in weight and four times the rvalue.
All pumice aggregate should be uniformly prewet to reach total saturation, then be allowed to sit while excess water drains out. This will fill the internal voids of the pumice with water. Prewetting the mix will prevent its drying out on the way to the placement site and slump will be uniform throughout the load, and from load to load
Pumice is a naturallyoccurring rock that has many practical applications. It can be obtained in large chunks or thin powders. While most of the world39s supply of pumice is used in construction materials, it is also widely used as an abrasive in cleaning supplies both for personal use and for use around the home.

Pumice Aggregate is seen as a preferred choice to other materials due to its weight, where the pumice is a third lighter than other 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
Pumice p m s , called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. It is typically light colored. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles, thicker vesicle walls and being dark colored and denser.
The main use for pumice is as an aggregate in lightweight building blocks and assorted building products. The other major applications for pumice and pumicite include abrasive, absorbent, concrete aggregate and admixture, filter aid, horticultural including landscaping, and the stonewashing of to receive an email notification when a publication is added to
PumiceCrete is a low density, lightweight, lowrise structural concrete using 38 pumice aggregate, Portland cement, and water. The honeycomblike walls are formed and poured at a typical thickness of 1824 inches, with no additional structural reinforcement 03 or insulation needed.
Pumice Gravel A premium light coloured bubbly volcanic glass, suitable for theatre, film and television props, Koi Carp filtration systems, photographic assignments and light weight concrete. Pack size 8kg Stone Size Approx. 1014mm Stone Colour Light grey white Coverage 8kg of 1014mm pumice will cover approximately 34m 2 at 20mm depth.
What is Pumice Pumice is a lightcolored, extremely porous igneous rock that forms during explosive volcanic is used as aggregate in lightweight concrete, as landscaping aggregate, and as an abrasive in a variety of industrial and consumer products.
Pumice is solidified foam that forms from lava rich in gases. It has numerous pores in the form of bubbles and irregular cavities that absorb moisture. This lightweight stone is used to amend garden soil improving aeration and drainage while maintaining moisture levels. 3834 x 0 sized Pumice 1434 minus with about 20 fines. Our pumice is horticulture grade, pH neutral, and available in 2 sizes.
Lightweight Concrete Aggregate Lightweight pumice aggregate for crafttype precast concrete projectsincluding statuary, containers, paverswhere a smaller aggregate size 38 to 18inch stones with some finessand is desirable. Lightweight Pumice Sand Pumice sand includes tiny 18inch stones. Use in lighweight mortars and as an
ray CT scanning of a typical fine pumice aggregate. The porosity of the pumice is clearly illustrated by the relatively large internal and external voids. Figure 1. Crosssection of pumice aggregate Courtesy of Dr. N. Kikkawa PUMICE AGGREGATES UTILISED IN THIS STUDY Pumice aggregates were obtained from the
The grading of an aggregate has a considerable effect on the workability and stability of a concrete mix and it is for this reason that grading of both the pumice lightweight aggregate and the normal aggregate was carried out to establish whether pumice qualifies as an aggregate according to BS 882 5. The following procedure was followed in
It is the use of pumice aggregate and sand that provide the lightweight advantages of pumice concrete by reducing the dead load on structural supports, trusses, girders and slabs. Pumice is a porous, naturallyoccuring volcanic glass, riven with airfilled vesicles formed by the expansion of trapped gasses when the molten lava is expelled into
The pumice aggregate samples were taken from Golcuk region of Isparta in Turkey .Pumice aggregates obtained from the quarry were first crushed by a primer crusher and then it was screened into three different sizes of 816 mm as CPA, of 48 mm as MPA and 04 mm as FPA in order to mix for lowstrength lightweight concrete.
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. The final product is lightweight concrete that is strong and durable with excellent insulating, sound dampening and fire resistance
Concrete made with pumice aggregate was used to build this ancient Greek temple way back in 126 A.D. Heavyduty soaps may contain pumice. Its used in landscaping as a drainage rock as well as soil conditioning.
