3 Ways to Break Up Concrete

The American Concrete Institute (ACI) is a leading authority and resource worldwide for the development and distribution of consensus-based standards, technical resources, educational programs, certification programs, and proven expertise for individuals and organizations involved in concrete design, construction, and materials, who share a commitment to pursuing the best use of concrete.Cinder blocks, made from pouring concrete into a cast, are used as walls in buildings or as support units for other structures. While these blocks can handle both weight and weathering, the cinder block does have weaknesses. In fact, elements from the outside, and occasionally from within, can damage, crumble and destroy cinder blocks. · Use a sledgehammer for thin slabs. If your concrete is 4 in (10 cm) thick or less, try using a sledgehammer.
