Let us consider the volume method for the calculation of cement & sand quantity. Use good quality of cement & Sand for plastering. Cement : Sand . This is the wet volume of mortar. In this article, I will discuss how to calculate bricks, cement, and sand in brick masonry. Brick Masonry Stone Masonry Cement Concrete Plaster. Mortar - 1 part cement, 4 to 5 parts building sand. Cement Mortar Required: Plastering thickness = 12 mm Sum of ratio is = 7. We will calculate cement and sand for 100 m 2 plastering area in 1:6 ratio and thickness of 12 mm. Here is the useful Plaster calculator to calculate cement and sand for plastering. Suppose we have to construct the wall having a volume of the 1-meter cube, the size of brick is going to use is 190 mm ×90 mm ×90 mm and mortar is 8 mm thick with the ratio of 1: 4. Step 3: Calculation. If you want to plaster with concrete mix then take 1 part cement and 2 part concreting sand. First of all calculate total volume of RR masonry.Then add 33% of volume more than actual volume of wet material.then for 1:4 ;1 cement:4 coarse sand.Total volume/5=Vol of cement. If you want to calculate cement and sand required for this mortar, you need to convert this wet volume of mortar into dry volume. Wet volume = 1m3. no of bags of cement=Vol of cement/.035.For 1:6 just put 6 in place of 4. Assuming, Volume of brickwork = 1 m 3; Grade of mortar = 1:6 (cement : sand) First class brick (190 mm x 90 mm x 90 mm) Thickness of mortar = 10 mm = 0.01 m; No. For wall plastering, the ratio of Cement : Sand = 1 : 6. Use good quality of cement & Sand. 4. Quantity of dry mortar required = 324 x (42/100) = 136.08 m 3 Mortar Proportion ( 1 : 6 ) For wall plaster generally ratio we use = 1: 6 (1 part of cement and 6 part of sand). Sand required (6 Parts) = 1.86 m³ X 6/7 = 1,59 m³ 3.) Calculating Dry Volume of Mortar 5. Cement to sand ratio ranges from 1 part cement to 3 to 4.5 parts sand, depending on the type of mortar being mixed and the compressive strength desired. The difference between mortar and cement is that cement is the bonding agent, while the mortar is a product composed of cement, sand, and lime.. Remember that the mix ratio of mortar is 1 : 6, that means 7 parts = 1 Cement + 6 San So,Cement required (1 Part) = 1.86 m³ X 1/7 = 0,265 m³. i.e. Cement mortar ratio should be 1:6 for 9” Brickwork and 1:4 41/2” brickwork ; Mortar thickness should not be more than 10 mm between the courses and sides of the bricks; Ensure you are using good quality of cement and sand. Cement required = 1/6 X 0.0266 = 0.00443 cu m ( cubic meter) Sand required = 5/6 X 0.0266 = 0.0222 cum Step-4: To get the weights of materials required in multiply it with its density Step 5 Please specify the Mix Ratio . The thickness of the mortar should not be more than 10 mm between the courses and sides of the bricks. The strength of 1:6 ratio of mortar after 28 days is 3.0 N/mm2. The requirement of Rubble 1.3cu and Sand 0.3cu, and 5 Cement bag per 1cu of rubble masonry. total cement consumption in bags: total sand consumption in m3: total aggregate consumption in m3: total brick consumption in nos. Step 1 ... Total Quantity of Work. More water, cement or sand can be added if the mixture is too wet or dry. We Know in one bag of cement = 1.226 CFT For Calculate in CFT (Cubic Feet) = 8 x 1.225 = 9.8 Cubic Feet CALCULATION FOR SAND QUANTITY; Consider volume of concrete = 1m 3 . of 50 kg bag of cement, 0.42 m 3 of sand and 0.83 m 3 of stone aggregate. Sand = {6 / (1+6)} x {1.25 x1.25} x1.07 ==1.4 Cum While calculating, it is multiplied by25 % each to compensate Dry to Wet volume conversion & for wastage part (some companies use lesser or higher percentages also) and1440 is density of cement and divided by50 to get the answer in bags. Part of cement = 1/7. Large Batches of Concrete Mixes. It is reported that, for traditional screeds a mix proportion of 1:6 Portland cement: sand/aggregate is a normal range that is commonly used. Dry Volume of Concrete = 1 x 1.54 = 1.54 m 3 Sand= (1.5/5.5) x 1.54 = 0.42 m 3 ∴ 1.5 is a part of Sand, 5.5 is sum of ratio . Mortar calculator for laying bricks or blocks. Step-3: The mix ratio of mortar is 1:5, So total ratio = 1+5 = 6 in which one part is cement and 5 part is sand. Density of Sand is 1450/m 3. Example – For brickwork in 1: 6 cement mortar = 0.3/ (1+6) = 0.043 cum. Masonry is 42 % of actual stone masonry volume. Cement mortar ratio should be 1:6 ratio for 9-inch Brickwork and 1:4 ratio for 4& 1/2” inch brickwork. In order to calculate the amount of Cement, Sand or Mortar required or brickwork firstly find out the amount of mortar required for brickwork. Use measuring box (not head pan) for site mix. The above formula will give the dry volume of cement mortar, So to get wet concrete volume, we have to multiply the dry volume by 1.55 Total Parts = 1+5 =6. For a Sample calculation, I will assume a 12mm thick plaster and a mix ratio of 1:6. Requirement of dry mortar for U.C.R. total water consumption in liters: 5 % is added in the total to account for wastage. The quantity of sand? The quantity of cement?. STEP 3: Calculate the total volume of sand and cement.
