Step 4.6 Topping up the leg forms
Start shoveling A mixture of sand, gravel, water and cement which hardens to a stone like condition when dry. into the leg forms.
But as you go….
More rapity tapity tap
As you go, tamp, poke, prod, with a broad stick – say a piece of plastic, steel, or Timber, lumber. The hard fibrous lignified substance under the bark of trees about ⅛” (3mm) thick x 1½” (38mm) wide.
Do a lot of rapity tapity tap around the sides of the leg forms.
It would spoil an otherwise good job if the end product was full of air-pocket holes and gaps for the lack of a bit of rapity tapity tap
Once filled and settled, remove the excess concrete.
Have a bit of a clean-up
The next morning you can clean up a bit more.
All the splashed and spilled concrete should scrape off from the form easily enough if the form work was adequately coated with the release agent.
That’s pretty much it for a while.
Let it sit there for three or four days.
Let the concrete How much the teeth are angled out on a circular saw blade. (cure) slowly
The longer concrete takes to set (cure), the stronger it will be.
Keep the concrete shaded during the The hardening of concrete. The process of becoming hard or solid by cooling or drying or crystallization. In concrete application, the process in which mortar and concrete harden. The length of time is dependent upon the type of cement, mix proportion, required strength, size and shape of the concrete section, weather and future exposure conditions. The period may be 3 weeks or longer for lean concrete mixtures used in structures such as dams or it may be only a few days for richer mixes. Favorable curing temperatures range from 50 to 70 degrees F. Design strength is achieved in 28 days. period.
Keep the concrete moist for at least a day or so by hosing with a fine mist every now and then. This is more crucial in warmer conditions.
The release agent, apart from just being a release agent, also serves another purpose. It prevents the moisture in the concrete from soaking into the form, thus helping to prevent the concrete from drying out too fast.
