Concrete block calculator
Calculate and the answer is 0. A concrete block calculator really helps when doing an estimate or a proposal for a concrete masonry wall.Choose Round Column (or Round Slab) on the calculator.They are 4 feet in height and 10 inches in width (diameter), or 4′ x 10″. Also enter quantity and price to calculate total volume and cost of materials when you enter the price per cubic foot, price per cubic yard or price per cubic meter.įor example, let’s say you have 50 round concrete form tubes, sonic tubes, Sonotubes or cement tubes that you need to fill. Enter dimensions in US units (inches or feet) or metric units (centimeters or meters) of your concrete structure to get the cubic yards value of the amount of concrete you will need to make this structure. For vertical bars, avoid the centre of the core (single bar per core).įor horizontal steel (bond beams with 2 bars) the steel should be in the upper half of the block.Calculate volumes for concrete slabs, walls, footers, columns, steps, curbs and gutters. If you have to drill through a solid filled core, try to miss the steel rebar. Running all the way to the top of the wall in that core. Concrete blocks are often made of 1:3:6 concrete with a maximum size aggregate of 10mm or a cement-sand mixture with a ratio of 1:7, 1:8, or 1:9. These will normally be in the centre of a hollow core, and indicate wiring or plumbing So you don't need to go into the wall centre.Īlso look for electrical, plumbing (or any other) outlets on the inside of the wall first. Obviously it's easier to drill into the hollow core from each side of the wall, To make sure the position you choose is actually an empty core, drill a very small hole to check - if you go more than about 50 mm without breaking through,īE AWARE that any electrical or plumbing work will likely also be placed in these hollow block cores (before the concrete is poured) so once you've drilled through the outer wall of theīlock and into its hollow core LOOK INSIDE TO CHECK WHAT's THERE. Usually the top 2 courses of the wall are solid filled (a bond beam from wall top to 400 mm down)Īll wall ends and corners, each side of all openings, and above all openings are also normally filled.Īlso vertical cores (top to bottom) at given horizontal centres (maybe 600, 800, 1200 etc) - These you cannot guess easily. To see where the concrete and steel goes (preferably not a place to drill) Normally the wall is concrete filled, as the diagram above shows. If the wall is not concrete filled, ALL these points are hollow and easy to drill.
To make quick repairs in patio slabs and reset loosened stones or bricks in a walkway or retaining walls. As a binder between bricks in walls, fences, and walkways. To seal any gaps to resist wind or rain penetration. To compensate for irregularity between units. If the wall is rendered or sheeted, and you can't see the block joints, from the wall end, measure horizontally to any odd multiple of 100 so: 100, 300, 500, 700, 900 etc.įrom the bottom of the wall measure up the same odd 100mm measurements to find the centre of the empty cores. Adhering bricks or concrete blocks to one another to provide stability. Horizontal (bed) joints up or down 100 mm to the empty core centre. So from a block end measure Horizontally 100mm or 300mm, and vertically from the
If you can see the block joints, just make sure you position the hole in a hollow core. Here, we will demonstrate easy step by step process to calculate the concrete blocks used for civil construction. To find the empty core centres (the easiest location to cut) do this: Calculating the quantity of blocks needed for a building is a straightforward process that does not require any previous building or architectural skills. The entire 190mm of concrete block, through a concrete filled and steel reinforced core, or only through the 2 ~ 45 mm sidewalls of the block into the hollow core (much easier). If you need to drill or cut a hole through a 200 Series concrete filled masonry wall, depending on where the hole needs to go you may have to cut through In this guide, we’ve put together a concrete block calculator formula to help you work out how many concrete blocks you’ll need, and how much they cost.
