Consider thickness of plastering 12mm in case of internal plastering,20mm in case of external plastering and 6mm in case of ceiling plastering. After converting into KG=.05×1440=72KG. 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. Sum of ratio is = 7. So let’s get started. Step 3: Calculation. Excess of Alumina in clay makes the brick crack and wrap on drying. Example – For brickwork … Bricks are available in different classes and sizes. of bricks = (Volume of brickwork / Volume of one brick with mortar), Volume of one brick without mortar = 0.19×0.09×0.09 = 0.001539 m3, Volume of brick with mortar = (0.19+0.01) x (0.09+0.1)x (0.09+0.1), ∴ Total no. Masonry is 42 % of actual stone masonry volume. Here, for 1:6 mix, total number of ingredients in the mortar is 6+1 = 7. We shall use DLBD method (Dry Loose Bulk Density) in determining the ratios. and they are further classified into three classes based on the quality of brick. Quantity of cement in Cement Mortar. Your email address will not be published. So, The required cement is (.30×1)/6= 0.05 cum. In this article, I will discuss how to calculate bricks, cement, and sand in brick masonry. Density of Sand is 1450/m 3. 4) calculate quantity of cement Sand for brickwork of 10m3. 3- First class brick (190 mm x 90 mm x 90 mm), No. Cement Calculation. To calculate the cement quantity ; The ratio of cement mortar is 1:5. ratio of mix is 1: 6 in which one part is cement and six part is sand. The thickness of plaster is between = 12 mm to 15 mm. ∴ Sand = 0.30426 x 35.3147 = 10.7448 cft. Considering voids in sands, we assume that materials consists of 60% voids. Your email address will not be published. ■ meaning of mix 1:6 mortar:- in this mix ratio of cement and sand in which one part is cement and 6 part is sand and by adding water. STEP 3: Calculate the total volume of sand and cement. 2- Grade of mortar = 1:6 (cement : sand) 3- First class brick (190 mm x 90 mm x 90 mm) 4- Thickness of mortar = 10 mm = 0.01 m. No. When water is added to dry mixture of cement and sand, hydration of cement occurs, and it binds with sand particles and the surrounding surfaces of masonry and concrete. To get update of latest post signup below by giving you email address. Mix ratio is = 1:6 ( one part is cement and 6 part is sand), ■ calculation :- we know that while we calculate dry volume of cement mortar cofactor 1.54 is multiply in wet volume of mortar considering wastage of mortar and volume increase, Dry volume =wet volume × 1.54 The sum is 1+5 =6. 1:6 ratio of cement mortar is usually used for brickwork. Fired brick and Non fired brick. Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Calculation of Cement and Sand in Mortar Approximate method to determine the quantity of materials of mortar for 1cum brickwork divide 0.3 by the sum of the numerals of the proportion of materials which gives the quantity of cement in cum. Lime:- Brick consists of 0.8-2% of Lime in it. For Roof plaster mainly ratio we use = 1: 4 (1 part of cement and 4 part of sand). Procedure for calculation is: 1. Required fields are marked *. Why Bamboo Is More Stronger Than Steel Reinforcement? Save my name, email, and website in this browser for the next time I comment. Mixing of cement and sand mortar ratio can be changed depending on the strength should obtain but the most frequently used ratio is 1:5 (cement:sand) mix, which we are going to discuss in this article. In order to calculate the amount of Cement, Sand or Mortar required or brickwork firstly find out the amount of mortar required for brickwork. of cement bags = 73.0224 / 50 = 1.45 bags (1 bag cement contains 50 kg cement), Sand = (Dry volume of mortar x Sand ratio)/Sum of the ratio, Sand = (0.35497 x 6)/7 = 2.12982/7 = 0.30426 m3. A rich mortar of more than 1:3 is prone to shrinkage. Other constituents:- Magnesia, Sodium, potassium, manganese and iron oxide. For calculation purposes, lets assume that the area that needs to be plastered is 100 sqft (10 ft X 10 ft wall) and a Plaster of Mix ratio 1:4 (cement:sand) is 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 . Most mixes also require the use of lime in various proportions as a binding agent, to increase the longevity of the finished product, and to increase the workability of the mix. Concrete - 1 part cement, 2 parts concreting sand and 3 parts 20 millimeter aggregate. If you want to plaster with concrete mix then take 1 part cement and 2 part concreting sand. Mortar quantity is 0.2305 (Wet Condition) we calculate Dry Value Dry Mortar Value is = 0.2305 x 1.33 = 0.306565 m3. Excess of lime in brick may cause to melt and distort during burning. “First Class, Second Class and third-class bricks.”. Sand required (6 Parts) = 1.86 m³ X 6/7 = 1,59 m³ When converted KG into the number of bags= 72/50=1.44bag. We know that cement mortar is used for many civil work like brick masonry, plastering work of internal and external sometime it is also used for dpc work.
