Youn Can Do Small Concrete Jobs

It is not unusual for someone in the concrete block making business to be asked to do various kinds of small concrete jobs for customers. This is actually a very good source of some extra revenue. Ready Mix concrete which is sold in bags is the fast and easy way to do this work. You just have to add water to the dry concrete mix and you will have top quality concrete which can be used to do any job. You can, if you wish, mix the concrete from scratch but it is simply not worthwhile for a small job. The only possible error you can make with the use of dry concrete mixes is to add too much water. If you do this accidentally, which will happen occasionally, just add additional dry mix to correct the problem.

The tools you will require for this work are a pointed trowel, a wooden float and a rectangular finishing trowel. When you are making repairs on concrete there are certain rules which it is necessary to follow. All loose material must first be removed. Cracks in the concrete should be chiselled out so that they are wider at the bottom than at the top. This "keys" in the repair material so that it will not break loose. Before pouring the concrete into a crack, saturate the old work with water. This will prevent the water from being leeched out of the new concrete.

Concrete uses water to initiate a chemical reaction which causes the cement particles to bind onto the sand and gravel in order to form a solid rock like mass.
Lack of sufficient water will make a weak crumbly concrete that will very soon deteriorate and have to be replaced. Too much water is also a bad thing as it floats away the cement particles from the sand and gravel.

Pre-made mortar mixes are the best solution for building a fireplace,barbeque or the foundation for a small building. The correct proportions of sand,cement and lime in these premixed bags gives a consistent color and quality of work.
