11.5 CEMENT AND CEMENT LIME PLASTER 1 1.5.1 Suitability of Cement lime Mixes The weaker mixes of cement Lime plaster containing smaller proportions of cement, shall not be used in conjunction with a strong finishing coat. Weaker mixes offer certain advantages Over the stronger (richer) mixes when applied to non-rigid backgrounds, such as lathing. Ensure you are using good quality of cement & Sand (In silt content test, we have discussed how bad sand quality affects the work) Volume of plaster = Area of plaster x Thickness of plaster = 9.29 x 0.012 = 0.11 m³. Thickness of plaster varies according to type of work generally it is 6mm and 12-15mm. Cement mortar 1 : 4 ( 1 cement : 4 sand ) 3. with 1:4 C.M. consumption of materials in concrete is 5 percent less when aggregates with highest values of fineness modulus are used instead of those with lowest ... *Specification for sand for plaster. 12 Sep 2018 12 Sep 2018. Norms for Consumption of Materials for building works D:\Office Work\Website\upload\SOR\Azamgarh Circle SOR.xlsMaterial of Building works 9 Brick work in 1:4 cement and fine sand Cu.M 1.86 - - 0.27 - 460 - - 10 Plaster 1:1:6 cement lime and fine sand a. Cement plaster is a homogenous mixture of Portland cement, fine aggregates, and water. 10mm thick rough face Sq.M 0.057 - - 0.013 - - - - Cement mortar 1 : 5 ( 1 cement : 5 sand ) 4. In order to calculate the required quantity of cement, sand and water for plastering we have to follow the following 5 simple steps. Standards and Code Compliance – DensShield Tile Backer in 1/4” (6.4 mm), 1/2” (12.7 mm) and 5/8” (15.9 mm) thicknesses conforms to current IRC and IBC codes and is manufactured to meet ASTM C 1178 as a fiberglass mat gypsum substrate for use Volume of plaster = 0.11 b+ (20×0.11/100) = 0.13 m³. This is wet volume, we need find out dry volume. (10 sq.mtr) area of 12 mm thickness Generally, OPC 43 and OPC 53-grade cement is mixed with sand (the fine aggregate) in different proportions; hence, this plaster is also called as the cement-sand plaster. If there is a need for an additional coat don’t do that at one go. Providing and laying skirting and dado of polished Shahabad stone 25 to 30 mm. ... (1) (2) 1. Use good quality of cement & Sand for plastering. Step 1:- Assumptions Area of Plaster … Method-1: DLBD method to Calculate Cement, Sand and Water required for Plaster (1:4) 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. For ceiling plastering, the ratio of Cement : Sand = 1 : 4. Substrates Substrates can be either metal lath, unit masonry, monolithic concrete, or a recommended gypsum base, cement board or gypsum fiber panel. Cement mortar 1 : 3 ( 1 cement : 3 sand ) 2. How much Cement, Sand & Water required for plastering. Mix should be done with proper weight mixing or volume mixing. We shall use DLBD method (Dry Loose Bulk Density) in determining the ratios. Now we need to add extra 20% for joint filling, depression and wastage. Cement required for enabling work and cement required for testing purposes will be taken into account for consumption purpose. Plaster systems typically consist of a substrate, a basecoat plaster and a finish plaster. Example Cement and sand Required in Plaster. Tag: cement consumption in plaster 1:4. Estimation and Costing. PPC cement is preferred in place of OPC-grade cement … Mix ratio of plaster = cement : sand = 1: 4. 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. So, Amount of plaster mortar (1: 4) yielded with one Bag of cement (50 kgs) = 336/2200 = 0.153 cum Step-3: Calculate Plaster Volume Required Amount of plaster mortar required for plastering 100 sq.ft.
