Concrete cost calculator

The direct cost of concrete typically includes the costs that are directly associated with the production and delivery of concrete. This may include:

Materials: The cost of the raw materials used to produce the concrete, such as cement, sand, and aggregates. This might also include things like various chemical additives or fibers to change the properties of concrete to suit specific jobs.

Labor: The cost of labor to mix, pour, and finish the concrete, including wages and benefits for the workers.

Equipment: The cost of any equipment needed for the job, such as mixers, pumps, and tools.

Transportation: The cost of transporting the concrete to the job site, which can include fuel, maintenance, and labor costs.

These costs are typically the primary costs that a concrete supplier or contractor will consider when pricing a job, and they are directly related to the amount of concrete that is needed for the job.

There are certain aspects of concrete cost that have to be considered during the planning stage. For example if cement or other aggregates are purchased in bulk quantities, the price is going to be cheaper compared to purchasing lower quantities of breaking down the total volume of aggregates into batches and purchasing them separately.

A medium sized job will use hundreds or even thousands of cubic yards of concrete and cost of aggregates plays a crucial role in the profitability of the project.

Another important point to consider is the packaging the material is purchased in. It is a bit less important for sand and gravel, however the type of packaging that you purchase cement in will greatly affect the cost. The cheaper options would be bulk bags or using a horizontal or a vertical cement silo. This will ensure the preservation of this most expensive component of the concrete mix and also allow to save some $.

When calculating the cost of concrete produced with Carmix, you can use a comprehensive cost calculator that we have on the our website.

				Net cost of 1 yard3:	$81

Important points to consider here would be:

Grade of concrete you are planning to produce: every grade has its own mix design and therefore the proportion of the mix components changes which in turn affects the price of concrete.

Best price for each type of aggregate available for your project. Price of concrete components varies considerably not only between different states, but even between various areas within the state. A lot of factors affect the cost of aggregates, but a considerable portion of that would be transportation to the jobsite.

The US Bureau of Labor Statistics (BLS) does publish monthly data on the producer price index (PPI) for concrete products, which includes cement. The PPI measures the average change over time in the selling prices received by domestic producers for their output, and can provide a general sense of price trends.

According to the latest available data from the BLS (as of December 2021), the PPI for concrete products was 235.8, which represents an increase of 9.9% from the same time the previous year. However, it’s important to note that this figure is for all concrete products and may not be representative of the price of cement alone.

Storage of aggregates:

Organizing the storage of concrete components on the jobsite is important to ensure that the materials remain in good condition and are easily accessible when needed. Here are some steps you can take to organize the storage of concrete components on the jobsite:

All aggregates should be stored on hard, flat and level ground within your site.

Identify a suitable location: Choose a dry, level area that is close to the mixing and pouring site, but far enough away to avoid interference with the ongoing work.

Separate the components: Store each component separately, such as cement, sand, and aggregates. This will make it easier to measure and mix the materials accurately.

Keep the area clean: Keep the storage area clean and free from debris, as this will help to prevent contamination of the materials.

Protect the materials: Cover the storage area with a tarp or other suitable covering to protect the materials from rain, sun, and wind. This will help to ensure that the materials remain in good condition and are not wasted.

In order for Carmix to maximize its output and performance, aggregates need to be placed close to each other and not too far from the pouring site to avoid unnecessary travel between loading and pouring.

Another important aspect is access to water. It would be optimal to have a water tank onsite and allow Carmix to use its high output onboard water pump to provide needed quantity of water for the mix. If you only have a garden hose with medium water pressure available, it will take a lot of time to fill up the tanks with 250 gallons of water per batch.

Once all the points mentioned above are addressed and optimized, the actual concrete production with Carmix is pretty straight forward. Concrete cost calculation would typically include adding up materials used for the batch and multiplying every material by its price. You will also need to calculate the price of diesel used for every batch of concrete, the operator’s wage, the portion of periodic maintenance cost of Carmix. If we consider that one full batch of 4 cubic yards can be produced in 20-30 minutes, then it becomes possible to calculate how much time is spent per every cubic yard.

After that it is a matter of dividing the outcome by 4 to get the cost of 1 cubic yard of concrete.
