It is well known that we need about 10 blocks to build one square metre of wall. Length (ft): ... Mortar bags needed for block count. This value is given by the manufacturer and is stated on the bag. Only available in Gauteng. Concrete is a material comprised of a number of coarse aggregates (particulate materials such as sand, gravel, crushed stone, and slag) bonded with cement. Bond two or three of the blocks that will be used together to see how the mortar sets up. Cement 1/7×4.5=0.643m3 x 1440=925.92kg/50kg= 18.5bags Find our very useful calculator below to assist you with the correct amount of building materials you will require for your new Project. Planning a project can be difficult to plan and budget for. Considering voids in sands, we assume that materials consists of 60% voids. Cement = 0.043 × 28.8 = 1.238 bags ( Numbers of cement bags in 1 Cum = 28.8 ) Sand = 0.043 × 6 = 0.258 cum. Dry volume of mortar = Wet volume of mortar x (1+0.33) [33% of volume] Mortar quantity is 0.2305 (Wet Condition) we calculate Dry Value Dry Mortar Value is = 0.2305 x 1.33 = 0.306565 m3. The volume of a standard builder’s wheel barrow = 0.065 cumecs Vertical mortar = 8 x (0.025 x 0.225 x 0.275) = 0.0123 m 3 Horizontal mortar = 10 x (0.0637 x 0.025) = 0.0159 m 3 Total = 0.0282 m 3. It’s practically correct and applicable in sites in Nigeria. Simply type in the height and length of a wall that you want to build and click on Calculate at the bottom, we will work out how much sand and cement that you need on the right of this page. Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Look at it this way. For each calculation you will have to know the dimensions of your object. The calculator will perform the sums for you - where relevant it will add a small percentage for the wastage that inevitably happens when mixing & using cement-based products, and then it will round the result up to the nearest whole 20kg bag. Our free brick calculator helps you work out how many bricks you need. Test the mortar to make certain it will hold as desired. You will also need to make allowances for broken blocks, known as wastage. In this article, we are going to explain how you can estimate the quantity of mortar (cement and sand) needed to lay blocks per square metre of wall. How do i calculate cement and sand quantity in 1:3 mortar? 5. This calculator is based on a 3/8" mortar joint. For example, a wall area of 210 square feet requires 237 blocks because 210 multiplied by 1.125 equals 236.25. Approximately one bag of cement lays 80 blocks. Aggregate, Gravel & Cement. Don't mix all the mortar at the same time. Simply enter in the dimensions of the wall you need to build and hit calculate. 1’1″ =1.083′ , 9″ = 0.75′ ,8″ = 0.666′. Bond two or three of the blocks that will be used together to see how the mortar sets up. If, on the other hand, it does not, adjust the mortar formula by adding more dry or wet ingredients until the right mixture is obtained. Nice Content Thanks for sharing .. BIM documentation in India BIM Consulting in India cad services in India BIM Solutions in India BIM Project Management in India. Use the block calculators below to calculate the amount of materials needed. Bricks, blocks and mortar (sand & cement) calculator. Structville is a media channel dedicated to civil engineering designs, tutorials, research, and general development. The calculator we have built below helps save time with manual calculations. Please enter the dimensions in the white fields below. Material quantities in kilograms; Material quantities in 25kg bags A wall measuring 10 feet by 10 feet has an area of 100 square feet, for example. But as the cement will go to fill up the voids in the sand, 0.045 cum of cement and 0.27 cum of sand may be taken. Cement= (1/5.5) x 1.54 = 0.28 m 3 ∴ 1 is a part of cement, 5.5 is sum of ratio Density of Cement is 1440/m 3 = 0.28 x 1440 = 403.2 kg We know each bag of cement is 50 kg For Numbers of Bags = 403.2/50 = 8 Bags We Know in one bag of cement = 1.226 CFT Calculating the correct mortar mix materials for your wall is important to ensure you build the wall correctly and keep costs economical. The calculator will then tell you the number of bags you need based on the different size of bags we carry. You have entered an incorrect email address! He is a Fellow of the Royal Geographical Society and the Royal Meteorological Society. After adding water to the mortar mix, it bulks and reduces the volume by 33% during wet condition. Dry volume of a mortar = 0.2305 cum X 1.33 = 0.306565 cum Therefore the volume of mortar required to lay one square metre (1 m2) of 9 inches block (with hole) can be taken as 0.03 m3 for all practical purposes. The volume of mortar required = 0.03 x 150 = 4.5 m3, Typical mix ratio for mortar (laying of blocks) is 1:6, Cement requirementQuantity of cement required = 1/7 x 1440 kg/m3 = 205.71 kgMaking allowance for shrinkage between fresh and wet concrete = 1.54 x 205.71 = 316.79 kgQuantity of cement required in bags = 316.79/50 = 6.33 bags. Our basic calculation was 9504 kg of sand and 29 bags of cement (that is 1450 kg of cement). Therefore, there are about 96 unheaped wheelbarrows in 10 tonnes of sand, which is 384 headpans of sand. Using the 1: 6. For each calculation you will have to know the dimensions of your object. On average, it takes about three bags of cement for every 100 blocks.
