What is the difference between a concrete slab and a cement slab?
What is the difference between cement and concrete? Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement.
Is it cheaper to buy premixed concrete?
It’s cheaper to do all the prep and buy the concrete premixed and delivered. For example, a 10×20′ slab of 4″ concrete would be a minimum of 2.5-3 yards. Here concrete is about $80/yard (closer to $70), or $240 for the concrete. That same slab would take 223 40-pound bags, or 112 80-pound bags.
Do you need gravel under concrete?
Whether you pour concrete for a walkway or patio, a strong gravel base is required to prevent the concrete from cracking and shifting. Gravel is especially important in clay soil because it doesn’t drain well, which results in water pooling under the concrete slab and slowly eroding the soil as it finally drains.
Do you need rebar for 4 inch slab?
No, you do not need rebar for a 4 – inch slab of concrete on grade. A 4 – inch -thick slab cast on the ground and in permanent contact with it will float and rebar is not required. Rebar is recommended on concrete measuring 5 – 6 inches thick.
Is it cheaper to make your own concrete?
One of the least expensive ways to get concrete is to mix your own. You can buy bags of the mix from a home improvement store. Typically, you only have to add water for it to be ready to pour. Otherwise, you risk getting a weaker concrete once it cures, which could lead to cracks or crumbles within a couple of years.
Should I put plastic under concrete?
Recently, though, research has shown that the old traditional layer of 6-mil Visqueen (polyethylene plastic ) under the slab is seldom effective for two main reasons: Although it may seem water-tight, this grade of material allows a lot of water vapor to pass through.
Is sand a good base for concrete?
Pour concrete over a solid, well-drained base of sand or gravel over clay and other poorly draining soils to provide even support.
How deep should I dig for a concrete slab?
Excavate the slab area to a depth of about 7 inches, allowing 3 inches for a gravel base and 4 inches for concrete.
Is asphalt cheaper than concrete?
Lower upfront cost: Asphalt is less expensive than concrete to install. It could be about half the price per square foot to install asphalt. Although it requires more repairs than concrete, asphalt repairs are more straightforward than concrete because the cracks can blend into the original.
Which is cheaper stamped concrete or pavers?
Pavers cost about the same as stamped concrete in most instances. Since they usually do not require replacement, pavers offer better cost efficiency over time.
What Stone goes under concrete slab?
Because concrete is a very porous material, it will absorb any moisture that it contacts. This can cause pooling. Without crushed stone, pooling water will settle under it and erode your slab. Adding a layer of crushed stone will add proper drainage, as well as create a barrier between your slab and the ground.
