Find Out dry Materials Required for 1 cum. Brick Masonry in Cement Sand mortar 1:5 Ratio.

Dry Materials Required for 1 cum. Brick Masonry in Cement Sand mortar 1:5 Ratio.

Solution:-

Ratio = 1:5 (Cement, Sand)
Sum = 1+5 = 6
Total Dry Mortar for 1 cum Brick Masonry = 0.30733 Cum

Therefor, the Following Materials are Required:-

Cement = 1 x 0.30733 x 28.8 / 6 = 1.47 Bags
Sand = 5 x 0.30733 / 6 = 0.2561 cum.

No. of Bricks Required for 1 cum. Brick Masonry = 500 no's.

Materials Required for 1 cum. Brick Masonry in 1:5 Ratio.

Cement = 1.474 Bags = 73.70 Kg
Sand = 0.2561 cum. = 9.043 Cft

Note: 500 Bricks are Required for 1 cum.Brick Masonry.

Find Out dry Materials Required for 1 cum. Brick Masonry in Cement Sand mortar 1:5 Ratio.

Volume = 1 Cum.

Taking standard Mortar Thickness = 10mm

Cement –Sand Ratio = 1:5 = 1 + 5 = 6 Sum of Ratio.

We know that, Size of a Modular Brick = 190mm x 90mm x90mm

Volume of 1 Brick with Mortar = 200mm x 100mm x 100mm

= 0.2 x 0.1 x 0.1 m = 0.002 Cum

Therefore,

Number of Bricks in 1 Cum = 1/ 0.002 = 500 nos.

Volume of 1 Brick = 0.19 x 0.09 x 0.09 = 0.001539 Cum

Volume covered by 500 number of Bricks = 500 x 0.001539 = 0.7695 Cum

Volume of Mortar =1- 0.7695 = 0.2305 Cum { This is wet mortar }

For Dry Mortar, add 1/3 of the Wet Mortar = {( 1/3 ) x 0.2305} + 0.2305 = 0.30733 Cum

Now calculating the quantities of cement and sand in the 1:5 ratio,

CEMENT = {1/( 1+5) } x 0.30733 = 0.0512 Cum

= 0.0512 x 28.8 =1.474 Bags = 73.70 Kg {1 Cement Bag = 50 Kg }

SAND = {5/(1+5)} x 0.30733 = 0.2561 Cum

= 0.2561 x 35.314 {1 Cum = 35.314 Cft } = 9.043 Cft

Medlum Density Fibre Board (MDF)

Medium Density Fibre Board (MDF) MDF IS made from wood and other lignocellulose material refined into fibres and reconstituted with a resin binder. Row wood material is normally a single species wood. MDF has homogeneous structure with uniform density, texture and properties throughout, no identifiable grain can be seen at edge, end or face. There are no internal voids or pits and there is no variation in the surface hardness. Unlike plywood MDF doesn't delaminate. It has much higher strength than particle board. Since edges are totally smooth and uniform, costly tipping or beading with strips of wood required for plywood and particle board is not essential. It can be carved, grooved or embossed just like any timber. The surface of MDF is totally smooth and accepts all kinds of finishes - paints, varnishes and laminates. One such type of famous board in the market is 'Duratuff" . It comes in both interior and exterior grade. Duratuff prelaminated boards are also avail...

How to Calculate Cost and Quantity of 1000 Sq.ft Concrete Slab?

Cost and Quantity of 1000 Sq.ft Concrete Slab 1000 Sq.ft = 92.93 Sq.mt. Thickness of Slab = 0.150 Sq.mt. Volume of Slab = 92.93 X 0.150 = 13.939 cu.mt. Beam Volume = 20% o f concrete Vol. =13.939 X 20/100 = 2.7878 cu.mt. Total Slab Volume = 13.939 + 2.7878 = 16.768 = 17 cu.mt. We know :- M20 Grade of Concrete (1 : 1.5 : 3) Concrete Quantity of 1 cu.mt. Cement = 8 bags Sand = 15 cu.ft aggregate = 30 cu.ft 1 cu.mt Concrete Cost = 4,550 Rs. So :- M20 Grade of Concrete (1 : 1.5 : 3) Concrete Quantity of 1000 cu.mt. Cement = 17 X 8 = 136 bags Sand = 17 X 15 = 255 cu.ft aggregate = 30 X 17 = 510 cu.ft 1000 cu.mt Concrete Cost = 77,350 Rs. Steel Quantity = 1% of concrete Vol. =17 X 1/100 =...

How to Calculate Estimation of Wall Plaster.

Assume: Wall = 1m Length, 1m height Mortar Ratio = 1:6 Plaster Thickness = 12 mm =0.012 m Constants: Density of Cement = 1440 kg/m3 1 cum = 35.3147 cuft. So: Volume of Mortar = 1 x 1 x 0.012 = 0.012 cum. (Wet Volume) Dry Volume of Mortar = 0.012 x 1.30 = 0.0156 cum. Quantity of Cement = 1/7 x 0.0156 x 1440 = 3.21 kg = 0.064 Bags Quantity of Sand = 6/7 x 0.0156 x 35.3147 = 0.47 cuft. The recommended thickness of cement plastering is given below. Recommended thickness of plastering for brick walls is 12 MM, 15 MM or 20 MM. 12 MM thick cement plaster is done where the plain surface of brick masonry is plastered . 15 MM cement plaster is required on the rough side of 9” and 4.5” wall .
