Pumice pozzolan is the natural, sustainable pozzolan the Romans so successfully used in their millenniadefying concrete mixtures. So, based on modern research done by top national scientists and on the evidence provided by millenniadefying Roman concrete, when it comes to selecting the ideal pozzolan, HessPozz is the clear choice.
Weight Pumice concrete also reduces the live load of formwork and false work. Pumice Concrete delivers a high fire – rating the standard concrete and will not spall under contact with direct flame. Thermal conductivity is low in Pumice Concrete. Acoustical ratings are higher for pumice Concrete as .
Pumice is widely used to make lightweight concrete or insulative lowdensity ''breezeblock'' type bricks. When used as an additive for cement, a finegrained version of pumice called pozzolan is mixed with lime to form a lightweight, smooth, plasterlike concrete. This form of concrete .
Hess Pumice Products sources a pumice deposit in demand worldwide, and supplies that pumice to a variety of industries for a variety of uses, refined and graded to meet over 300 different specs. We''ve been in the business of pumice for over 50 years, and, quite frankly, we''re very good at it. Using Pumice in Concrete. Decorative Precast ...

Pumice Concrete Pumice concrete has been used for various structures in New Zealand for over 100 years. The first documented appliion was for structural wall elements in Tudor Towers, the former Government Bathhouse in Rotorua, which was built in 1906. Pumice concrete
· Pumice is widely used to make lightweight concrete or insulating lowdensity concrete blocks. When used as an additive for cement, a finegrained version of pumice called pozzolan is mixed with lime to form a lightweight, smooth, plasterlike concrete.
The term "pumice" usually refers to large pumice stones; pumicite is a finegrained ashy version of pumice which formed in the presence of higher gas levels. Nearly threequarters of all pumice and pumicide that is produced annually is used in lightweight construction materials, such as .
The pumice liner system comes in a range of 15 diameters from 150mm to 1000mm internal diameter. The Pumice flue liners are for masonry chimneys where the linings are surrounded by 100mm of brick, block or stone. The linings are suitable for all fuels but not suitable for condensing appliances –including pellet or biomass.
The term "pumice" usually refers to large pumice stones; pumicite is a finegrained ashy version of pumice which formed in the presence of higher gas levels. Nearly threequarters of all pumice and pumicide that is produced annually is used in lightweight construction materials, such as concrete block and concrete.
To analyse the effects of CPA, MPA and FPA/cement ratios on the nonstructural concrete engineering properties, the range of different pumice aggregate/cement (A/C) ratios of 6:1, 8:1, 10:1, 15:1 ...
Pumice Aggregate SelfCompacting Concrete (PASCC) could be a viable alternative to artificial LWASCC in countries rich in natural lightweight aggregates, such as Greece. Pumice is a highly porous volcanic aggregate with low bulk density (300 kg/m3 – 800 kg/m3) and high water absorption capacity (30% – 80%, by weight).
Pumice is scrubbed against jeans to give them a fashionable, wornout look. Another wide use of pumice is in concrete. Pumice can be added to cement mixture to create a lightweight concrete. It is also used in decorative precast concrete. This type of concrete is perfect for finishing off structural buildings and is inexpensive.
