A siliceous, or siliceous and aluminous, material which in itself possesses little or not cementitious value but will, in finely divided form and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form compounds possessing cementitious properties. - ASTM C125

Famed Roman structures, such as he Pantheon, Colosseum and aqueducts, are still standing today. One secret to the long-term durability of these structures is that the Roman builders turned to volcanic ash to harness the power of pozzolans. Like Roman concrete, fly ash pozzolans in the chemically-balanced formulas of Magna Wall™ products react to free lime, forming additional cement binder. This leads to greater durability of the Magna Wall™ line of products.

The modern-day equivalent of ancient pozzlans is fly ash, which comes from coal-burning power plants. The spherical shape of fly ash particles allows them to flow and blend more freely in cementicious mixtures. The spherical shape creates a "ball-bearing" effect resulting in a lubricating action when concrete is in its plastic state, creating benefits in workability and improved finishing.

The Magna Wall™ line of stuccos, mortars and masonry cements have been scientifically formulated to include fly ash as an active ingredient in order to improve both the durability and workability of the product. The testing labs at Best Masonry have developed individual, chemical formulations of Portland cement and high quality fly ash for each of our stuccos, mortars, and masonry cements to maximize the overall performance of the given product.
