Nevada Pozzolan Ltd is seeking a joint venture partner to develop our multimillion ton natural pozzolan deposit into production

What is Natural Pozzolan?

Natural pozzolan is an aggregate industrial material used principally as a replacement for coal fired fly ash and secondarily as a partial replacement for Portland cement in concrete. Natural pozzolan increases durability and reduces cost of concrete while providing a near 100% carbon offset. It is the green solution to harmful coal based concrete products.

Derived from volcanic ash, natural pozzolan was named after the Italian city Pozzouli located just outside Naples, where it was discovered and utilized by ancient Roman architects as a durable building material. Natural pozzolan has been used in projects ranging from the Pantheon of ancient Rome to modern engineering marvels like the Golden Gate Bridge and the Bonneville Dam.

Aggregate Industrial Material for Concrete

Today concrete is one of the most widely used materials in the world, however modern coal fired energy processes necessary in the production of Portland cement contribute large portions of greenhouse gases. As a result, over half of the coal fired plants have closed in the US reducing the supply of fly ash typically used in concrete and creating a demand for an alternative, natural pozzolan. As the supply of coal ash diminishes, natural pozzolan is becoming the mainstream choice for concrete producers.

Chemistry & Geology

The volcanic tuff with pozzolanic properties is the Bluestone Mine Tuff as described by Proffett and Proffett, 1976, “Stratigraphy of the Tertiary Ash-Flow Tuffs in the Yerington District, Nevada”, Nevada Bureau of Mines and Geology, Report.

Large Deposit of Volcanic Tuff

Our natural pozzolan deposit is a large deposit of volcanic tuff, up to 980 feet thick and over one mile in length. The tuff is a white, crystal-poor, unwelded rhyolitic tuff, tuff-breccia, and sediments containing two poorly welded , red to brown ash-flow tuffs.

Excellent Performance and Durability

A series of samples indicate the volcanic tuff has pozzolanic properties that meet or exceed ASTM C618 guidelines and has the potential for production of tens of millions of tons of natural pozzolan. An initial bulk sampling program of up to 36,500 tons has been permitted with the Nevada Division of Environmental Protection.

One Hundred Percent Carbon Offset

A supplementary cementitious material, as a replacement for coal fired fly ash and Portland cement in concrete, natural pozzolan provides a near 100% carbon offset and reduces embodied carbon in structures and slabs.

Historic Building Material

Discovered and utilized by ancient Roman architects as a durable building material with cementitious properties when mixed with water, natural pozzolan was used to build the Pantheon in Rome, the largest non-reinforced concrete dome ever built and still standing today.
