If the wall is going to be exposed to lots of wind and rain you'll need the mix to be stronger, so use 1 part cement to 1/2 part lime and 4 . Cement plaster is a thin layer of paste applied on the wall surface. To make my calculation easier I will convert feet unit in meter unit. Add wastage of 3% = 0.04 3% = 0.0012 cubic metre. Cement to sand ratio for brickwork:- as per general guidelines, for block/ brick work or masonry construction or mortar mix, typically, ratio of cement to sand is 1:3 (1 part cement to 3 parts sand), 1:4 (1 part cement to 4 parts sand), 1:5 (1 part cement to 5 parts sand) and 1:6 (1 part cement to 6 parts sand . Since the amount of cement and sand changes with the change in the mix ratio, it is one of the most important factors in determining the quantities. Cement Mortar Ratio for wall plastering 1:6; Cement Mortar Ratio for ceiling plastering 1:4; Plastering thickness should not be more than 12-15 mm. Let us consider the volume method for the calculation of cement & sand quantity. 1000 kg = 1 Ton. Besides, you can also use PPC cement for attaining your desired plasterwork. Area of plaster = 100 sq.ft = 9.29 m. Thickness of plaster varies according to type of work generally it is 6mm and 12-15mm. The ratio you use will depend on what psi strength you need. Answer (1 of 8): For wall: A good solid surface is recommended to reduce water being absorbed by the mortar mix. However, mix proportions of 1:4 cement to sand is widely applied which comply with British Standard (BS12). Sand and Cement Plastering. The average thickness of plastering should also be a minimal 20 mm which includes two coats. For ceiling plastering, the ratio of Cement : Sand = 1 : 4. (1X1.6/1+6)/0.347 = 6.58 bags of cement. Mix cement and sand in the ratio of 1:6 (1 cement:6 sand) for inner plastering of bricks.

Quick Facts On Cement Mix Ratios Sand increases the amount of entrapped air Aggregates in mix will increase air pockets Trapped air that isn't sufficiently vibrated will show pinholes The ratio of Cement Mortar for Ceiling Plastering = 1:4. PPC cement can also be used instead of OPC in plastering work. I detail tools and their use, plus explain and show a variety of useful plastering tips. Cement plaster is made by mixing cement, sand, and water, usually, the ratio of cement and sand is 1:4. To prepare the cement plaster mix, OPC 43-grade is generally mixed with sand in different proportions. And for outer plastering mix it in the ratio of 1:4. Cement Mortar Required: Plastering thickness = 12 mm = 12/1000 = 0.012m. Plastering Calculation- Step 1. Step 4. Mix ratio should produce a plastic, easy-working, cohesive mortar of plastering consistence. Plaster to Water Ratio Chart Construction and other decisions should NOT be based on the results of this calculator. Step 2. Cement quantity = 0.2/ (1 + 4) = 0.04 cubic metre. At one go, avoid plastering of more than 12mm thickness. This statistical calculator for cement and sand for plastering is provided for your personal use and should be used as a guide only. 1:6 mix ratio of cement and sand are used for internal wall plastering when fine sand is available. The cement-sand ratio for wall plastering (12 mm thickness) would be 1:4 i.e., for one part of cement four part of sand. That's why it's usable both inside and outside and it's durable against weather and once it cures, it makes a really hard surface. Use good quality of cement & Sand for plastering. If you desire more of a concrete appearance, with slight mottling, use a ratio of 2 parts cement, 1 part sand and 1 part gravel. Cement:Sand = 1:5, 1 part of cement and 5 parts of sand in a mortar).

Quantity calculation for plastering work: I will tell you the easiest way to estimate the quantity of cement & sand by taking a sample of 10sq.m area of the wall with a thickness of 12mm. Mix Ratio of Plaster: Mix ratio mean the ratio of Volume of Cement to the Sand used in the mixture. 1 Bag of cement in cubic metres = 0.0347 cubic metre. Hence, to maintain 3 parts dry sand, moist sand will have to be added in 3*1.05 part = 3.15 part. Watch this video explains the Sand to cement ratio in Stucco, Portland plaster sand mix ratios. With a small bit of attention, you can and will save cash, create a sense of euphoria and sleep well knowing, no problemo, I did this repair myself. The wet volume of the mixture is always less than the dry volume. C - cement required (1 part) S - sand required (5 part) X - 35% sand bulkage. Since wet volume is always less than the dry volume. Volume of mortar = 9m2 x 0.012m = 0.108m3 Ratio for Plaster Taken is = 1 : 6 Sum of ratio is = 7 Calculation for Cement Volume Dry Volume of Mortar = 0.108 x 1.35 = 0.1458 m3 Cement= (1/7) x 0.1458 = 0.0208 m3 Density of Cement is 1440/m3 = 0.0208 x 1440 = 29.99 kg We know each bag of cement is 50 kg = (29.99/50) = 0.599 Bags On a brick wall never do plastering of thickness more than 12 or 15mm. Ideal Ratio of Cement Sand mix for Plastering Always keep few things in mind before plastering calculation. Either 9 or 4.5 MM thick and 15 MM thick cement plaster in 1:4 ratios is recommended on the rough side of the walls. Sand Density = 1450-1500 kg/m 3. Plaster of mix ratio 1:4 mean that it contains one part of cement and 4 parts of sand by volume. Volume of cement mortar required = ( Plastering Area x thickness . Thread starter Do_It _With_Dave; Start date Jan 29, 2019; Members online. .

Step 6. = ( 1.95 3 4 ) 1550. 3. Since wet volume is always less than the dry volume. Cement quantity in liters in 1 bag of cement = 34.7 litres. 1550 is conversion m 2 to . These mixing ratios are based on the proportions of cement : sand : stone in that order. Consider the cement mortar ratio 1:4. What is the proper mixture for plastering? Please do read the plastering checklist post for the complete list. The required cement is (.301)/6= 0.05 cum After converting into KG=.051440=72KG When converted KG into the number of bags= 72/50=1.44bag. After that you will be able to calculate as per your desired area. For wall plaster generally ratio we use = 1: 6 (1 part of cement and 6 part of sand). If the surface is to have a lime-putty finish,then it is advisable to have rich mix of 1 part of cement,1 part of lime and 3 parts of sand.For any rough finish a mix of 1 part of cement to 3 to 4 parts of sand is recommended. Cement Mortar Required: Estimation of Water, Cement & Sand quantity for Cement Mortar. Cement sand ratio for plastering | thickness of wall plastering and know about cement sand mix ratio for plastering and thickness for types of external plast. Thickness of plaster = 12 mm = 0.012 m.
