Some concretes are even designed to harden more quickly for applications that require rapid set time. Alternatively, in some factory settings, concrete is mixed into dryer forms to manufacture precast concrete products such as concrete walls. The process of concrete hardening once it has been placed is called curing, and is a slow process.
Step 3: Calculate the amount of each ingredient based on the mix ratio and the total volume of concrete. For example, let’s say you need to pour 1 cubic meter of concrete using a 1:2:3 mix (1 part cement, 2 parts sand, 3 parts aggregate). The total parts of the mix are: \( 1 + 2 + 3 = 6 \, \text{parts} \) This means for 1 cubic meter of concrete:

Concrete is a composite material used for all kinds of construction projects, especially where high compressive strength is required. It is composed of fine and coarse aggregate which are bonded via fluid cement paste that hardens over time - usually about a week to reach over 50% of its final strength and a couple of weeks to reach 95% of it. Comp...
The final step can be done for a custom mix by calculating the required amounts of gravel, cement and other materials based on the chosen proportions (percentages). Scroll down for more on concrete density and redymix versus custom mix concrete.
Given that there is usually some percentage of concrete lost or wasted during the mixing and pouring process, it is a good idea to consider buying 5-6% more concrete than estimated, to be on the safe side.
The volume formula for a rectangular (or square) slab in cubic feet is height(ft) x width(ft) x length(ft), as seen in the figure below: For example, 1ft x 3ft x 6ft = 24ft3 (cubic feet). For example, to calculate the volume in cubic meters for a wall with a height of 2m, width of 20cm and length of 4m, you need to multiply 2 x 0.2 x 4, which equal...
curb depth * (curb height + flag thickness) * length + gutter width * flag thickness * length, where each component is as illustrated below:
Estimating volume is easy but estimating the required concrete weight (mass) is harder, as we need to know the density of our material, usually given in kg per cubic meter (kg/m3). It is also referred to \"density in place\". Conventional concrete has density between 1900 kg/m3 and 2400 kg/m3 and can endure, on day 28 of its pouring, and has a comp...
Standard U.S. concrete is usually about 2130 kg/m3, which is also the default in our concrete calculator, but you can enter any density in it to customize the calculation. Lightweight concrete is usually below 1500 kg/m3, while electrically conductive concrete is between 1450-1800 kg/m3.
Concrete manufacturers often don't specify the density of their concrete mixture directly, but instead give you the bag yield of the material in place. For example, a conventional redymix concrete bag of 80 lbs may be listed as having a yield of approximately 0.60 cu ft or a 25 kg bag may have a yield of ~0.01 cu m. With a few simple mathematical t...
Did you know that concrete was known and heavily used in ancient Rome[2]? Romans were so good at making concrete, that some of it is in perfect condition even today, some 2 millennia later. Rather than eroding, like most modern concrete the material seems to gain strength from the exposure, particularly in the presence of sea water.

Using our concrete calculator is simple and straightforward. All you need to do is enter the dimensions of your concrete project, whether it’s a round slab or concrete column. The calculator will then give you three key variables: the total volume in cubic feet, cubic meters, and cubic yards. You can even choose round column or flag thickness ...
Calculate the amount of concrete needed for your project. Calculate the concrete needed to pour a slab (rectangle or circle), patio, footing, column, steps, or post-fill-project in cubic yards or meters, or pre-mix bags, and estimate the cost of materials. IMPORTANT: The concrete calculator is solely intended to estimate the amount of concrete ...
Jul 30, 2024 · Our concrete calculator makes working the cost of a concrete slab easy. Once you know how much concrete you need (in bags) and how many slabs you'll produce out of it, simply provide the price of the bag, and you'll receive the concrete slab cost, a cost to pave your desired area, cost per unit of volume and the total cost of the material you need.

Jul 10, 2024 · The amount of concrete you need for a 10x10 slab depends on how thick it will be. So, for a 4-inch slab you’ll need 1.24 cubic yards (56 80lb bags), but a 6-inch slab requires 1.85 yards (84 80lb bags). If your slab is a different size or thickness, use our calculator to determine the amount of concrete.
