Quantity of Cement and Sand Calculation




Quantity of cement mortar is required for rate analysis of brickwork and plaster or estimation of masonry work for a building or structure. Cement mortar is used in various proportions, i.e. 1:1, 1:2, 1:3, 1:4, 1:6, 1:8 etc.

Calculation of quantity of cement mortar in brickwork and plaster:

For the calculation of cement mortar, let us assume that we use 1m3 of cement mortar. Procedure for calculation is:
1. Calculate the dry volume of materials required for 1m3 cement mortar. Considering voids in sands, we assume that materials consists of 60% voids. That is, for 1m3 of wet cement mortar, 1.6m3 of materials are required.
2. Now we calculate the volume of materials used in cement mortar based on its proportions.
Let’s say, the proportion of cement and sand in mortar is 1:X, where X is the volume of sand required.

MARKET FORMS OF STEEL

Following are the standard shapes in which the rolled steel sections are available in the market- 1. Angle sections- The Angle section may be equal legs or unequal legs. The equal angle sections are available in sizes varying from 20 mm x 20 mm x 3 mm to 200 mm x 200 mm x 25 mm. The corresponding weight per meter length are respectively 9 N and 736 N. The unequal angle sections are available in sizes varying from 30 mm x 20 mm x 3 mm to 200 mm x 150 mm x 18 mm. The corresponding weight per meter length are respectively 11 N and 469 N. The angle section extensively used in the structural steel work especially in the construction of steel roof trusses and filler joist floors. 2. Channel Section- The channel section consist of a web with two equal flanges. A channel section is designated by the height of web and width of flange. These sections are available in sizes varying from 100 mm x 45 mm to 400 mm x 100 mm. The corresponding weights per metre length are respectively 5

Materials are used for road construction

Image
Road consist of basically 4 layers: Sub-grade: The sub-grade material should be clean and free from organic matter and should be able to be compacted by roller, to form stable sub-base. The material should have the following characteristics: ·          Well graded, uniformity coefficient (D60/D10) should not be less than 3. ·          Fraction passing sieve #200 shall not be greater than 2/3rd of the fraction passing sieve #40. ·          Should have a L.L not greater than 25%. ·          P.I not greater than 6 ·          CBR should not be less than 25. ·          In coarse grain, aggregate retained by #10 sieve, %age of wear shall not be greater than 5%. ·          The maximum dia of any particle shall not be greater than 2/3rd of the layer thickness of sub-base Typical particle size distribution for the sub-base (granular) which will the meet strength requirements are: 2.Sub-base Course: ·          It is layer of granular mat
