1cum 250mm THICK BRICK WORK CALCULATION

1cum 250mm THICK BRICK WORK CALCULATION

Brick size with mortar :- 250mm*125mm*75mm
Volume of 1 brick with mortar:- 0.250*0.125*0.075 = 0.00234cum.
Brick size with out mortar :- 240mm*115mm*65mm
Volume of 1brick without mortar :- 0.240*0.115*0.065 = 0.00179.
Nos of brick in 1cum with mortar:- 1/0.00234 = 427.4 = 427
Volume of 427nos brick without mortar:- 427*0.00179 = 0.76 cum
Required of cement mortar :- 1-0.76 = 0.24cum.
Now
Dry volume of mortar :- 0.24*1.33 = 0.32 cum
We know the mortar ratio :- 1:6
So, Cement :- 0.32*1/7*1440 kg = 65.8 = 66 kg
Sand :- 0.32*6/7 cum = 0.27 cum.

Types of bonds generally used in brick masonry.

Brick masonry is built with bricks bonded together with mortar. For temporary sheds mud mortar may be used but for all permanent buildings lime or cement mortars are used. The various types of bonds generally used in brick masonry are 1. Stretcher bond 2. Header bond 3. English bond and 4. Flemish bond. Stretcher Bond: A stretcher is the longer face of the brick as seen in the elevation. In the brick of size 190 mm × 90 mm × 90 mm, 190 mm × 90 mm face is the stretcher. However care should be taken to break vertical joints. This type of construction is useful for the construction half brick thick partition wall.This bond is sometimes known as running bond. This bond is the simplest bond that is used today, this bond is not suitable as a stand alone structural wall and a structural wall built directly behind it, fixed with wall ties would be needed. Header Bond A header is the shorter face of the brick as seen in the elevation. In a standard...

Classification of Brick

There are different types of bricks available on the market used for various kinds of purposes. These bricks can be categorized under various headings and subheadings on different basis. The various classifications of types of bricks are briefly discussed below. A. Classification based on method of manufacturing Bricks can broadly be categorized into two types as follows on the basis of how its manufactured: 1. Unburnt or sun-dried bricks 2. Burnt bricks 1. Unburnt bricks or sun-dried bricks Unburnt bricks or sun-dried bricks are the types which are dried with the help of heat received from sun after the process of moulding. These bricks can only be used in the construction of temporary and cheap structures. Such bricks should not be used at places exposed to heavy rains. 2. Burnt Bricks Burnt bricks are prepared by burning the brick-mould in the kiln inside the factory. These are th...
