Figure Concrete Walls
To determine how many bags of concrete you will need divide the total cubic yards needed by the yield. For concrete the formula for volume is as follows.

Wall sq ft width height.
Figure concrete walls. To figure concrete yardage start by breaking your project up into multiple rectangular prisms. Lets say that I wanted to build a wall using concrete blocks measuring 16 inches in length and 8 inches high with a mortar gap of half an inch. A structural reinforced concrete shear wall in a 5-story building provides lateral and gravity load resistance for the applied load as shown in the figure below.
The calculator will figure the amount of block and related materials fast and quite accurate. Port Hills loess Strength parameters. A concrete block calculator really helps when doing an estimate or a proposal for a concrete masonry wall.
C 0 φ 30 degrees. I want to know how many concrete blocks will be required and an estimate for the cost of the masonry project. Concrete Calculator - Figure out how much concrete youll need for your footings.
The example wall is shown in Figure X2. This calculator assumes that you are using 20 foot long lengths of Rebar. The amount given as needed does not include any waste.
When calculating materials for a concrete wall start by figuring out the desired volume. Input length and width of the area. The wall is assumed to be located in the Christchurch Port Hills.
Total Block Required. The following design assumptions were made. To use the Concrete Wall Calculator simply enter the width length and thickness of your pour.
It utilizes two independent concrete masonry walls side by side each meeting the required fire-resistance rating. There are several formulas to figure out how many concrete blocks are necessary for a wall project but youll need to start by measuring the walls width and height in feet. Use this concrete calculator to estimate the amount of concrete blocks needed to complete a project.
The base is divided into two parts the heel and toe. For each additional 20 foot increase of the wall. It is recommended depending on the job you are doing to add anywhere from an extra 4 to 10 to your concrete order to make sure you have enough concrete to finish the job.
Double Wall Fire Wall. The calculator will indicate the number of 50 lb. Calculate the amount of Rebar needed for reinforcing a wall.
Reinforced Concrete Cantilever Retaining Wall Analysis and Design ACI 318-14 Reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab. You can look up the recommended footing size based on the size and type of house and the bearing capacity of the soil. Use the following yields per each bag size.
This concrete calculator will help you in estimating the amount of concrete needed for your project. Concrete Block Calculator Estimator. Explore other calculators related to housing or building as well as hundreds of other calculators addressing finance math fitness health and more.
If each block has two voids then multiply the number of blocks by 2 to get the number of voids in the wall. With that information use the following formula to calculate the volume of your wall in feet and inches. The measurements to take are.
Essentially you are solving for volume and then converting to cubic yards. Figure 1 Reinforced Concrete Shear Wall Geometry and Loading. Find the Total Concrete Block Fill Volume.
Shear wall section and assumed reinforcement is investigated after analysis to verify suitability for the applied loads. Begin laying down the first level of concrete bags in the space where you intend to build the wall. Length x width x thickness.
If your wall is over 40 feet long it will add 2x the amount of overlap required. The calculator will automatically estimate the number of cubic yards of concrete that will be required. Reinforcing for combined foundation wallconcrete floor slabs supporting lightweight construction is described in NZS 36042011 Figures 713B 714B and 714C.
Remember the depth of the post hole should be one-half of the above-ground post height. If the combined foundationfloor slab supports masonry veneer cladding the reinforcing is described in NZS 36042011 Figures 715B 716B and 716C. Wall Volume height x length x thickness.
Double wall construction Figure 6 is generally easy to design and detail for loadbearing conditions especially for taller walls. Stagger this second level by placing the center of the bags on this layer over where two bags on the first level meet. Concrete cantilever wall example.
Use the block calculators below to calculate the amount of materials needed. The stem may have constant thickness along the length or may be tapered based on economic and construction criteria. Bags of QUIKRETE Fast-Setting Concrete you need.
Foundation walls to concrete slab on ground floors. 12 Example Wall. If your wall is over 20 feet long it will add the amount of overlap required.
Concrete can be ordered in ½ yard increments. Slump Slump is a. As you can see heavy houses on weak soil need footings 2 feet wide or more.
Use our concrete block calculator to find how many blocks are in your wall. Then convert all of the measurements for each prism to the same unit and find the volume of each. But the lightest buildings on the strongest soil require footings.
For a 6 feet above ground post use a post with an overall height of 9 feet and place 3 feet in the ground. We want the wall to be 15 feet high and 30 feet in length. Find Wall Square Footage.
Yes keep the concrete inside of the packaging. This calculator is to be used as an estimating tool only. A good rule of thumb is take your calculation and add 4 to 10 to the total to account for waste spillage over-excavation settlement spreading of forms loss of entrained air or any other changes in volume.
Once you have the wall measurements calculate the square footage by multiplying the width times the height. This free concrete calculator estimates the amount of concrete necessary for a project and can account for different shapes and amounts of concrete. Stack the next level of bags on top of the first.
Click the button to calculate the volume of concrete and man-hours not including mixing needed for this job.
