Pea gravel, crushed granite or asphalt.
There may be a sandy and dusty grid on a new concrete driveway due to wind blowing debris onto the concrete when drying. This may have also been mixed into the cement while it was being made.
Building a concrete slab is not difficult. Simply excavate the area where the slab is to go, and build a wooden box frame around it. Then, add crushed stone and pour the concrete on top. Finally, just smooth it out and allow it to dry.
Dig out app. 10 inches of soil. Fill 6 inches of hardpack (crushed concrete). This is for drainage and frost heave prevention. Bring in the concrete truck after renting floats and trowels and building frame. The whole driveway should be surrounded by 1X wood or PVC particle board sprayed with wd 40. The side of the 1X facing away from the concrete should have spikes in the ground and fastened to the board. You level the concrete to the top of these boards. It's like a big frame surrounding the project and you should take your time in building it, for level, runoff and evenness. Have a wheelbarrel and a few extra hands ready (the driver charges by the minute after a certain amount of time). The concrete should be fiber reinforced mix. This type eliminates the need for metal screening or fencing over the hardpack and suspended in the concrete for strength. Be advised, if you're in a snowy region, salt will be your only advisary, don't use it, salt eats concrete. You also need to put in stress gaps from side to side every 8 feet or more depending on width. When the concrete cracks it will crack along these lines. You do this when the concrete starts setting up but is still soft. Finish trowel all the edges. Screen the concrete with a long board across the width (from board top to board top and then use the float to smooth it. Keep a few wheel barrells full of concrete ready so you can get rid of the truck and still have concrete for leveling and fill after a majority of the concrete has been shovelled in. A tool rental agency may have tips and advice also.
Use the moveobjects on cheat and click on your flowers and place it on the concrete
Make chicken parm and put crushed garlic on top
Not really a good idea. The water over time from the concrete will cause the board damage. If you use a good pad there is no reason you cannot lay the carpet over concrete.
Put some stone on top of it... you might have to grade it down a little to keep the stone in place. That'll suit you a bit better.
No do to the concrete settling the concrete on top would split
I would start out by using a hot water pressure washer with a store bought driveway cleaner. You can rent one at your local hardware store. Chances are the muratic acid you used mixed with oil, dirt, or soap that was left behind on your driveway. Next, while the driveway is still wet, mix a small amount of the acid with water in a 5 gallon bucket. Use a disposable dust broom or masonry broom to scrub the acid into the concrete. You will notice that the acid will foam and have a froth on top. This is because the acid is burning the concrete. You will want to rinse the area you scrubbed the acid into right away with the pressure washer. If you fail to rinse ALL of the acid...your concrete will stain, which in your case is a tan color. I've cleaned a few brick and precast buildings in my time. P.S. Don't forget to wear eye protection.
there is not nearly enough information provided to answer your question. it isn't important that it is a tank or that it is a water tank. what is important is the thickness of the concrete, the shape it makes, the amount and location of reinforcing steel inside the concrete, the type of concrete, the foundation and the soil the foundation is on, how high in the air the top of this tank is (has repercussions for seismic areas), etc.
By putting a thin layer of new concrete on top.
You can buy a concrete bird bath top at Lowes. It is 2 inches high, and it's diameter is 18 inches. It comes in a gray/silver colour and is round. Lowes also do assorted bird bath pedestals to put the top onto.
