How to use a chainsaw like a pro watch?v=euzimnjuvf0&lc=z22cj1z5lu25ifkze04t1aokgfcmomxir1vy3glf0vgnrk0h00410part 1 demo of the old w. Odds are that any cracks will happen in these weakest parts. control joints can be made in one of three ways. 1. you can form them in still pliable wet concrete using a concrete grooving tool. 2.
This weakness in tension is why concrete is often reinforced with metal rods. the problem is, most concrete reinforcing rods are made of bare steel that’s prone to rust from water that sneaks into the concrete. when steel rusts, it expands, causing the concrete to flake off and come apart under internal pressure. Make crack control cuts: even with reinforcing rods or mesh in place, concrete slabs tend to crack over time. crack control cuts direct this cracking along a single line, so the results look better. let the concrete cure for two weeks, then rent a masonry cut off saw and create cuts 1 1 2 in. to two inches down in a grid of about 10 feet x 10 feet. Calculate the volume you need in cubic yards. multiply the length (10 ft.) by the width (10 ft.) by the depth (.35 ft., or 4 in.) and divide it by 27 (the number of cubic feet in a cubic yard). you get 1.3 cu. yds. then add 10 percent to allow for spillage and slab depth variations to help determine the concrete cost per yard. Step 9: using a float, smooth the concrete. for a truly professional job, use both a wood or bull float and a magnesium “mag” float to further smooth the concrete. first, apply the larger flat.

Stretch a string between two screws installed at the edge of both ends of the form boards. the string will act as a guide to keep the form boards straight. set the forms at the proper height. First off, “curing” is a process that begins as soon as concrete is poured. during this process, the ingredients in the concrete bind together and form the eventual concrete structure. during this process, moisture in the mix escapes to the top, often over the course of about 28 days. meanwhile, concrete cannot be said to be “dry” even.
