Concrete Block - Nominal vs Actual Dimensions Concrete Block (CMU) Sizes. Concrete Masonry Units (CMUs) are manufactured in a variety of sizes. They are identified by their depth – i.e. the thickness of the wall they create. For instance, a 6" CMU is nominally 6" deep while a 10" CMU is nominally 10" deep.

Fiberglass cement siding is a composite made of Portland cement, silica and wood fiber. Once painted, it looks almost identical to wood. It’s available in many styles and widths, both smooth and wood textured, and you still get the crisp joints and details that’ll make your home’s exterior stand out.

Concrete international By Jennifer a. GruBB, Hemant S. limaye, and aSHok m. kakade Although concrete typically begins its life at a highly basic pH of about 13, the pH values at exposed surfaces soon fall as reactions occur between carbon dioxide from the atmosphere and alkalis in the concrete— a process known as carbonation. Over time, fronts of

Concrete is generally sold in cubic yards. Since the measurement is currently in cubic feet, you need to convert that to cubic yards. Do this by multiplying the cubic feet by .037037037. 297.92 cubic feet x .037037037 = 11.03407406 cubic yards. Concrete used for this type of footing must be between 2,000 and 5,000 psi in compression.
