Lay a grid of rebar spaced four feet apart over the plastic and connect the intersections with tie wire. Divide the concrete slab down the middle with a 2×4 nailed to 1×3 stakes. Align the top ...

The concrete is poured onto the ground all at one time. Some foundations have post-tension cables or are reinforced with steel rods called rebar so that the slab can bear the weight of the house.

Concrete slabs crack unless you go all out to prevent and control those cracks; If something is worth pouring, it’s worth using reinforcing fibers in the concrete.

The objective of this text is to present one of the methods of pre-dimensioning slabs, beams, and pillars of buildings built with reinforced concrete. There are several other methods, but this is ...

In hopes of producing concrete structures that can repair their cracks, researchers from Drexel University’s College of Engineering are putting a new twist on an old trick for improving the durability ...
