Process Of Pouring Concrete
When you do concrete work it is important that you have the right concrete products and tools so that you can get the best possible concrete. If you have ever done a cement job without the right concrete products and tools then you know how hard it is to do a good job without them.
When you are preparing for a concrete pour, you may need to remove an old piece of concrete. If you do, then you should use a diamond saw blade in a concrete saw to make a clean cut on all sides of the piece that you are removing. This will make it easier to remove the concrete as well as give you a square piece to pour too, making it easier to come up with a nice looking new piece of cement.
After you remove the old concrete, it is time to prepare the ground for the new concrete. If the old concrete sunk and that is why you are replacing it, then you may need to add some base and do some major compacting work to make sure that the new concrete does not have the same problem. Once the ground is prepped, you then will need to place concrete forms. When forming, it is always better to use too many stakes rather than not enough. If you try to skimp by, you may find a form bulging from the weight of the cement during the pour, causing the concrete to not have a straight edge or a weird curve to it. For some concrete pours, you will also need to place rebar in the concrete area to reinforce the cement. When pouring the concrete where the rebar is, you will pour a little over it, then raise it up and let it sit on the bottom of the concrete and then pour over the top of it. The goal is to have it in the middle of the concrete as much as possible.
Before you have the concrete truck come to make the pour, you should be well prepared ahead of time. You will want to consider how large the pour is and if you are going to need some help. Can the cement truck pull up to the area to be poured and dump from the shoot? Will you need to wheel barrow the concrete to the pour site? Is it large enough that you should get a concrete pump? Do you know where all of your concrete tools are at?
When you get close to being ready, you will be able to call the concrete place and schedule the pour. Be ready to tell them how many yards of concrete you need them to bring. It is best to pour early in the morning if you can so that you have the whole day to finish the cement.
Once the truck arrives, it is time to go to work. The driver will want to know what slump you would like. This essentially refers to how runny or wet the concrete is. The wetter it is the longer you have to get it in place and worked, but it will also take a lot longer to set up. If you do not want to be there all day you can have the driver make it stiffer so that it will set quicker. If you are going to do this you need to make sure that everyone is moving quickly to get the concrete down and in place so that you can start to work the concrete as soon as possible.
The first step in working concrete is to make it level to the forms. This is done with a screed, which is usually a 2X4 board that is moved back and forth over on the top of the forms to scrape and move any concrete that is above the height of the form. Next, you will need to have someone working the float to bring the cream to the top.
While one person is working the float, another will come behind them and put a rounded edge on the top edges of the concrete using a tool called and edger. Another person comes behind them to smooth the lines with a trowel. This series of steps is repeated several times during the concrete curing time until the concrete is stiff enough to put the finishing touches on it.
One of the more under utilized of all concrete products by people who do not do cement work all of the time is diamond saw blades. However, it is one of the more useful tools in saving time in cement work.
