Uses of Pumice
25/12/2021 - tân hoàng - 0 Comment
The largest use of pumice in Vietnam is the production of lightweight concrete blocks and other lightweight concrete products.
When this concrete is mixed, the vesicles remain partially filled with air. That reduces the weight of the block. Lighter blocks can reduce the structural steel requirements of a building or reduce the foundation requirements. The trapped air also gives the blocks a greater insulating value.
The second most common use of pumice is in landscaping and horticulture. The pumice is used as a decorative ground cover in landscaping and planters. It is used as drainage rock and soil conditioner in plantings. Pumice and scoria are also popular rocks for use as substrates in hydroponic gardening.
Pumice has many other uses. Together these account for less than a few percent of consumption in the United States, but these are the products that most people think of when they hear the word “pumice.”
Lots of people have found small pumice pebbles in the pockets of brand new “stone washed jeans,” and almost everyone has seen the famous “Lava Soap” that uses pumice as an abrasive. Below we list these and some of the other minor uses of pumice (in no particular order).
