Cordova Stone units are high-density, pre-finished architectural concrete masonry units that achieve the look of natural stone by incorporating all-natural aggregates, delivering the prestigious appearance which has remained a desired look for centuries.
A All these terms deal with concrete masonry units produced using essentially the same finishing technique. They describe a process where roughly the top 1/16 in. of the exposed face is ground using an abrasive wheel to create a smooth surface exposing the concrete matrix (cement and aggregate.)
Concrete Masonry Walls can even be the veneer system itself with options such as smooth face, split-face, ground face, polished face & glazed face units. Concrete Masonry Walls used in a single wythe application can serve in both a structural capacity and also be the finished face of the wall.
Using concrete blocks on a project can even contribute to it being designated as a "green" building. Characteristics of Concrete Block. Concrete block is made from Portland Cement, aggregates and water. It is also known as a concrete masonry unit (CMU).
Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.
aggregate leveling pads, thus the footing does not need to be placed below the frost line provided there is sufficient foundation bearing capacity. The characteristics of the system allows for rapid and easy installation, even when completed ... National Concrete Masonry Association ...
Standard), which outlines a procedure to calculate the fire resistance ratings of concrete masonry assemblies. The 1997 edition of the Standard is referenced in the 2003 and ... concrete masonry units and the aggregate types used in their manufacture.
Concrete Masonry Fire Resistance . Concrete masonry noncombustible constructionis a material possessing excellent fireresistive properties. - The resistance of concrete masonry to fire is well established by extensive testing to be a function of the type of aggregate used in the manufacture of the masonry units and their equivalent thickness.
The thin-shell concrete masonry units are manufactured to meet requirements of ASTM C 90 as Grade N, Type I or Type 2. Due to the mold's thin shape, producer's use a concrete mix with 1/4 inch top-sized coarse aggregate and a higher cement content.
Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
Cranesville Block is a third generation family business that is Upstate New York's leading concrete producer. The company manufactures and delivers ready mixed concrete, block, sand and stone, precast, and retaining wall systems to commercial and residential customers.
At intervals of either 6 or 12 months, quantities of two slightly different lots of a material (cements, pozzolans, concrete aggregates, masonry sand, and masonry units) are …

concrete masonry units in this research were evaluated in the laboratory under conditions meant to replicate an automated manufacturing process. Concrete masonry units made with fine aggregate replacement consisting of waste glass and rubber tire particles were evaluated and compared to current engineering standards.
