You should or at least each wall at the same time. You could pour it in sections as long as the rebar was joining each section. The problem would be at the joints. How to form up a section of the footing with the re bar in place. If the rebar is not tied together, the wall will move and never be what it should be.
A pour of concrete, all at a single time. Also called a one-pour system. Contrast with two-pour system. At the same time you pour the floor, you are going to pour the perimeter footings. This is called a monolithic pour (or monolithic slab).
The average cost of concrete is 20 dollars per linear foot. This price does not factor in the cost of framing the footing or labor. The final estimate will include all concrete needed for the project.
Yes. Water is actually needed for concrete to set and is vital to the curing process. Concrete will set just fine under water. Depending on your specific application (will all of the pour be under water or will it start under water and finish above the water line) you may need to adjust the initial dryness of the mix as well as take more care in the pour. All of the volume of the concrete that is under water shoudl be poured in continuous fashtion. If you must pour in steps, the start of the next pour must be "in" the old pour so as to not leave a water survice between the pours. This "seam" will tend to stay and produce a weaker stucture.
Isolated footings are constructed invidually & Mat foundation is making of mat and connecting all footings with this mat
In larger concrete projects with a good quality control program, a pour card is a document that describes the location of the concrete being poured, type/specification of concrete being supplied, a signature block by the inspector and/or engineer indicating that the rebar has been inspected in-place and approved, date of pour, serial number of the concrete truck(s) supplying the concrete, sign-off by the inspector indicating on-site tests for slump and air entrainment (if required) have been completed. Temperature, weather and ticket info from the concrete batch plant/delivery truck are also recorded. The contractor's quality assurance manager will typically keep all the pour cards for a project on file, especially in the even that subsequent testing indicates substandard concrete was installed.
cement/ concrete is made with water, cement mixture and sand. After all of this is added to the right amount, you mix, mix, mix!! Then bofore it drys, pour it ontop the location desired

To calculate the amount of concrete needed, first convert all measurements to feet. The volume of concrete can be calculated using the formula: Volume = Length × Width × Height. For a thickness of 4 inches (which is 1/3 feet), the volume is 12 feet × 10 feet × (1/3) feet = 40 cubic feet. Therefore, you would need 40 cubic feet of concrete to pour the specified dimensions.
To determine if you have a monolithic foundation, check for a concrete slab that is poured all at once, typically encompassing the footing and foundation walls. Look for a flat, continuous surface without visible seams or separate footings. Additionally, you can inspect the structure's exterior; if the foundation is level with the ground and there are no visible blocks or piers, it’s likely monolithic. Consulting building plans or a professional can also provide clarity.
Once all ingredients are thoroughly wet (no "streaks" of dry cement) and the "slump" is correct, it is fully mixed.
Well, darling, the typical amount of cement in 1 cubic meter of concrete is around 350 kilograms. But hey, don't get too hung up on the numbers, just make sure you mix it well and pour it right. After all, concrete is like a good cocktail - it's all about the balance and getting the job done with a little flair.
