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).

2.3.3 Pretensioned and post-tensioned concrete—Concrete. is prestressed by one of two general methods: pretensioning and post-tensioning. When concrete is pretensioned, the tendons are stressed in the form before concrete is placed. When concrete is post-tensioned, the tendons are stressed after concrete is hardened.
Details
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 ...

Step 5: Break up the slab. Start with the point of the breaker touching the cement and then switch the tool on. The tool will start vibrating because it is hammering the point into the cement hundreds of times per minute. Hold the breaker firmly and upright and let the point crack and break the surface of the slab.
