Directions: First, select method A, B, or C at the top of the calculator: method "A" analyzes rectangular (tied) or circular (spiral) reinforced concrete columns — that is, calculates capacity or safe design (factored) load — given dimensions, number and size of rebars, concrete strength and steel yield stress; method "B" calculates rebar size and number given gross dimensions and design ...

Concrete blocks come in several standard sizes, the most common of which is called a concrete masonry unit (CMU). Other sizes are generally half of a CMU, measured either vertically or horizontally. Modern concrete blocks are made of a combination of Portland cement, heavy- or light-weight aggregate, water and additives to improve curing.
