Concrete slab cutting machine this article, we discuss all the technical specifications one needs to know in order to cut control joints. The time when the concrete slab is saw-cut to make control joints convrete an important aspect for the efficient use of control joint. Factors such as concrete mix, weather conditions, hardness of concrete slab cutting machine and types of machines used for making the control joints determine when to cut the concrete slab.

When the concrete is sawed with the help of blade before it has reached its initial setting time, the aggregates may strew out of the concrete slab and leave a messy, weakened edge along concrete slab cutting machine joint.

This effect is known as R avelling. The weather condition in which the cuts are made determines the time of making control joints.

In hot weather conditions, sawing can be started 4 hours after the concrete is poured. In cold weather conditions, sawing can be started 12 hours after the concrete is poured.

The best way to determine whether the slab cjtting ready is to make trial cuts to check for ravelling. Saw-cutting should start as soon as the ravelling stops during these trial cuts.

It is recommended to place the control joints concrte the centre of the slab dividing the concrete into equal segments. The spacing of the joints is in the range of concrete slab cutting machine to 36 times the thickness of cuttint concrete slab. If you are using high shrinkage concrete, you might want to decrease the cut spacing.

The factors that determine the location of control joints are :. The cohcrete 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 mm thick, the depth of the joint must be 40mm to 50mm. Concreete the joint is too deep, aggregate interlocking will not be sufficient to transfer loads.

If the saw cut is too shallow, random cracking might occur. The locations where the joints are to be made are calculated and marked using a chalk-line. It must be made sure that all the segments created are of the same size and the cuts are in a straight line. It is recommended to use machines for making the slan rather than lsab manual concrete slab cutting machine. If water-cutting equipment is used, make sure that the water is running all the way down to the blade.

The machine blade depth must be set to the depth of the control joint and the concrete slab must be sawed following the chalk mark. The saw cuts must be cleaned and filler material must be filled in the cuts to protect the reinforcement from corrosion and from a watertight joint.
