Best answer

Joints should be sawed as soon as the concrete will withstand the energy of sawing without raveling or dislodging aggregate particles. For most concrete mixtures, this means sawing should be completed within the first six to 18 hours and never delayed more than 24 hours.

Why is my concrete turning white?

Asked By: Ben Fortune Date created: Jun 13, 2022

Why is my concrete turning white? Efflorescence is a white salty residue caused when too much moisture is moving through the concrete. As the concrete dries and its moisture rises upwards through the slab, it brings salts within the concrete to the surface as well.

How do I know when my concrete is ready?

Asked By: Michael Foukarakis Date created: Jun 09, 2022

It'll soon reabsorb into the concrete. However, it's critical to wait until it disappears. Working the concrete before the surface “bleed” water disappears will weaken the surface of the slab when it dries. When all traces of the water are gone and the concrete starts to harden, you can resume finishing activities.

Why is my concrete cracking?

When concrete expands, it pushes against anything in its way (a brick wall or adjacent slab for example). When neither has the ability to flex, the expanding force can be enough to cause concrete to crack. Expansion joints are used as a point of separation (or isolation), between other static surfaces.

The thumb rule used to determine the depth of the control joint is to cut the joints one-quarter to one-third the slab thickness. If the concrete slab laid is 150mm thick, the depth of the joint must be 40mm to 50mm. If the joint is too deep, aggregate interlocking will not be sufficient to transfer loads.
