Abstract
A method for forming a concrete slab at a location subject to freezing temperatures is disclosed. Additionally, a method for forming a concrete slab with aggregate embedded at the exposed surface of the concrete slab is disclosed. The method contemplates utilization of a waterproof concrete mix.
Claims11
A method of producing a concrete slab having an exposed surface seeded aggregate, the method comprising the steps of:
- providing a concrete mixture having a waterproof admixture to produce a waterproof concrete mix;
- after the providing step, pouring the waterproof concrete mix over the subgrade, the waterproof concrete mix defining an exposed surface when poured;
- bringing up a quantity of cement/fines paste to the exposed surface of the waterproof concrete mix;
- broadcasting a quantity of aggregate upon the exposed surface of the waterproof concrete mix;
- mixing the quantity of aggregate into the quantity of cement/fines paste;
- and
- curing the waterproof concrete mix.
