Pouring concrete properly to make a well constructed slab is so easy to do with the right steps. Understand that there are two types of slabs. The ground and the upper slabs. Upper slabs need more attention to details than do upper slabs, though both need to be constructed well. Wrong pouring methods render slabs susceptible to cracks and tears sooner or later. This may mean re-doing them all over again. Make sure to be as meticulous as possible with construction and pouring details. This is vital in knowing how to prepare cement and how to pour a concrete slab. To avoid this unnecessary expense, here is how to pour a concrete slab.
Required Materials:
Concrete Aggregates (Mixed Portland cement, sand, and gravel)
Wooden forms
Required Tools:
Shovel or spade
Trowel
Smooth 2 by 3 by 10 lumber
Pail for concrete
Hand gloves
Rubber work boots
Steps on How to Pour a Concrete Slab
1. Determine whether to pour a ground floor or an upper floor slab. For ground floor slabs, make sure the concrete aggregates are proportioned 1:2:3. This means for every one part of cement, there should be 2 parts sand and 3 parts gravel. Simply put, for every sack of cement, use 2 sacks sand and 3 sacks gravel. Slabs used for upper floors should have a 1:1:2 ratio. This is a basic on how to pour a concrete slab.
2. Check the wooden forms. Wooden forms determine the final shape of the concrete when it hardens. For slabs, make sure the wooden forms are strong enough to withstand the pressure. There is great pressure when concrete is poured into them. Never pour concrete without forms when making a slab. If so, the desired thickness and shape will never be attained. Another important tip on how to pour a concrete slab is never pour into shakily constructed forms. It will compromise form quality sooner or later.
3. Check the steel reinforcement. Part of knowing how to prepare cement properly and how to pour a concrete slab is that concrete is useless without steel reinforcement. At least the steel bar size is 10mm. Check if the on-center spacing is even and if the tie wires are tight.
4. Make sure there are no debris on the areas where concrete is to be poured. Any kind of debris (pieces of wood, weeds, roots, or plastics) will affect the quality of concrete slab negatively. Remember this on how to pour a concrete slab.
5. Pour concrete slowly. If the mixture area and the pouring area are far apart, use the spade to put concrete on a pail. Then carry the mixture to the pouring area. If both areas are adjacent to each other, just use the spade for pouring. Make sure to spread the mixture evenly on all parts. Do this by piercing all sides and corners with the trowel. This action ensures that all nooks and crannies are filled in. It is important that no air pockets are produced.
6. Finally, even the top surface with a smooth 2X3X10 lumber. Simply slide it across the surface to produce a plain.
