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.

MACHINE FOUNDATION.

MACHINE FOUNDATION. The design of machine foundation involves careful study of the vibration characteristics of the foundation system. Relevant data for the design and construction of the foundation of machine should be obtained from the manufacturer of the machine , prior to the start design. All parts of machine foundation should be designed for maxim stresses due to the worst combination of vertical loads, torque, longitudinal and transverse forces, stresses due to temperature variation and the foundation dead load. In case, the foundation layout is partly built up of beam and column construction , straight bars should be provided both at top and bottom of the beams and the spacing of the stirrups should be close. The main foundation block should have the designed thickness and should be reinforced both at top and bottom even if the reinforcements are not required from design considerations. Machine foundations are special types of foundations required fo...

Concrete Mix Design

Concrete Mix Design Concrete mix design is the method of optimally dosing various components of concrete,such as cement, aggregates, water,and additives, to make concrete less costly and will have specific workability and homogeneity properties in the fresh state and strength and durability in the hardened state. Purpose of concrete mixes The main objective of the dosage of concrete mixes is to make a concrete that has the following characteristics: 1. Satisfy viability requirements in terms of drop to facilitate placement and consolidation. 2. Meets resistance requirements. 3. Can be mixed, transported, placed and compacted efficiently. 4. Economical to manufacture. 5. Meets durability requirements to withstand the environment in which the structure is expected to serve Mixing ratio procedure Step 1. Calculate the target average compressive strength for the mixing ratio: The target 28-day average compressive strength according to clause 3.2 of IS 10262. ft = fck + 1.65...

Column

Column. A column may be defined as an isolated vertical load bearing member the width of which is neither less than its thickness nor more than four times its thickness. Pier is a vertical load bearing member similar to a column except that it is bonded into load beating wall at the sides to form an integral part and extends to full height of the wall. A pier is introduced to increase the stiffness of the wall to carry additional load or to carry vertical concentrated load. Pier also strengthens the wall to resist lateral pressure without buckling. a supporting pillar especially : one consisting of a usually round shaft, a capital, and a base a colonnade of marble columns. something resembling a column in form, position, or function a column of water columns of smoke. The row is an order in which people, objects or figures are placed alongside or in a straight line. A vertical division of facts, figures or any other details based on category, ...
