3 Ways to Break Up Concrete

14/08/2019A 60-pound (27.2-kg) breaker should be sufficient for most home jobs. Only rent a heavy duty pneumatic jackhammer for extremely thick or difficult to break concrete. Only use a chisel point bit to break up concrete. This concentrates force, allowing the tool to break up the concrete more efficiently.

Breaking up reinforced concrete

20/03/2017So far I've been using a pick axe to expose the rebar, then cutting it with the angle grinder, but it's very slow going, and there's 20 meters of strip to break up. I could use a diamond cutting disc for reinforced concrete, but I think they may wear too quickly when cutting through such thick steel.

Why put Rebar in Concrete?

05/03/2018But we all know that concrete can crack and break apart. That's because concrete has a very weak tensile strength. Tensile strength is the force needed to pull something apart until it breaks. When steel rebar is added to concrete we now have a building material that is both high in compression AND tensile strength.

Expansion joints are usually a complete 'gap' between adjacent bays, ie, there is a definite break in the concrete and any reinforcing steel that may be present. Where adjacent bays are 'tied' together by means of dowel bars, these dowels are sleeved in one of the bays to allow expansion to take place without generating stresses within the slab.
