A Little About PozPyro

[phantom666]

It's a Silica Fume, Not to be confused with fumed silica.

Silica fume, also known as microsilica, (CAS number 69012-64-2, EINECS number 273-761-1) is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder that the research and development of silica fume made it one of the world's most valuable and versatile admixtures for concrete and cementitious products.

The specific surface area of silica fume can be measured with the BET method or nitrogen adsorption method. It typically ranges from 15,000 to 30,000 m²/kg. This makes it approximately 100 times smaller than the average cement particle.

Because of its extreme fineness and high silica content, silica fume is a very effective pozzolanic material. Standard specifications for silica fume used in cementitious mixtures are ASTM C1240, EN 13263

Silica fume is added to Portland cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance. These improvements stem from both the mechanical improvements resulting from addition of a very fine powder to the cement paste mix as well as from the pozzolanic reactions between the silica fume and free calcium hydroxide in the paste.

Addition of silica fume also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges. 

Furthermore, Silica Fumes has important uses in oil and gas operations. Silica fume can be used for a primary placement of grout as a hydraulic seal in the well bore, or secondary applications such as remedial operations including leak repairs, splits, and closing of depleted zones. 

 To use silica fume in various applications, in particular high-performance concrete. Effects of silica fume on different properties of fresh and hardened concrete include:

• Workability: With the addition of silica fume, the slump loss with time is directly proportional to increase in the silica fume content due to the introduction of large surface area in the concrete mix by its addition. Although the slump decreases, the mix remains highly cohesive.
•  
• Segregation and bleeding: Silica fume reduces bleeding significantly because the free water is consumed in wetting of the large surface area of the silica fume and hence the free water left in the mix for bleeding also decreases. Silica fume also blocks the pores in the fresh concrete so water within the concrete is not allowed to come to the surface.
•  may be used to produce silicon carbide. 

 BELOW - THIS IS FROM A FUMED SILICA PILOT PLANT!
                 using a PyroGenesis Reactor

IMO a PozPyro pilot plant would use LESS energy!

The energy required to produce 1 kilogram of fumed silica at commercial scale using PyroGenesis' FSR (Fumed Silica Reactor) in a pilot plant, has been reduced from an estimated 10-15 kWh to a range of 8-12 kWh.
This represents a 20 per cent reduction in energy requirements, which translates to a significant enhancement in the environmental benefits of the project. The HSPI FSR technology now requires 92 per cent less energy compared with conventional processes, which typically consume 100-120 kWh per kg of fumed silica produced.

The reduction in energy consumption and associated greenhouse gas emissions positions the FSR project as a potential game-changer in the industry. With energy production in Qubec generating 1.7 grams of CO2 equivalent per kWh, the HSPI FSR technology is expected to emit only 0.0136 kg of CO2 per kg of fumed silica produced. This represents a potential reduction of up to 99.9 per cent in the carbon footprint compared with conventional production methods.
