How to break up concrete
The best way of breaking into the concrete is to use a circular saw with a masonry blade attached. Once you have measured the area you want to have broken up, saw lines and use these to help start the process of breaking up the surface. When cutting the concrete you must wear a dust mask at all times. Concrete contains silica, which is ...

Reinforced Concrete vs Prestressed Concrete | SkyCiv
1. What is prestressed concrete. Simply put, it is concrete formed under stress. Reinforcement bars are placed in a form and stressed by the stretching of the bars at each end, inducing tension in the bar. Concrete is poured into the form and all around the bars while they are still being stretched. When they are released, the steel tries to ...

Reinforced Concrete
Suffice it to say, reinforced concrete is a French invention from the middle of the 17th century, but it may owe something to the British invention of chicken wire in 1844. Joseph-Loius Lambot made a ferro-cement boat and took out a patent for the idea in 1855 ( Courland, 2011, p. 218).
