We use 30% mortar in brick work, so 1 cum of brickwork has 0.3 cum of mortar.quantity for 1:6 mortar mix
cement quantity= 1/(1+6)*0.3
and sand= 6/(1+6)*0.3

full form of DMC Pilling

The bentonite suspension is pumped into the bottom of the hole through the drill rods and it overflows at the top of the casing.The water jet is let through the piling chiesel which comes out from bottom with Mud

gross area of steel-area of concrete=area of steel

d least count of theodolite is 20 sec

Least count of theodilite is 2" & dumpy level is .005mtr.

Bearing capacity of Soil is the maximum load carrying capacity of soil per unit area without any shear to soil.

A Resistance against load.

15% to 20% opening area for residential buildings.

It provides a solid base for the raft foundation n protect steel and concrete from corrosion. More over it help to maintain w/c ratio of raft concrete while it is casted green.

Working stress is elastic method and limit state is plastic method

Design of RCC Structures The design of the components of the RCC structure can be done in the following two ways: 1. Working Stress Method 2. Limit State Method Methods of RCC Design Here are som...

Steel detailing is the process of describing the reinforcement details like the number of steel bars, spacing, diameter of the bars, etc,. through or in the construction drawings.

Steel detailing is the use of steel reinforcement in concrete structures. It is part of the bending, binding & spacing of the bars. Length & space of the bars are based on the design consideration.

fineness means surface area per kg of cement.

Fineness of cement is nothing but number of particles in cement and its the early setting time of cement.more the fineness less the setting time .

m20-for 7 days it should be 67% and for 28 days it should be 100%...formula for cube testing:
ex: m20
size of cube surface area is 15*15 =225/10=22.5

for m20 7 days 20 * 22.5 * 67% = 301.5 kn.
28 days 20 * 22.5 = 450 kn.

Soundness of cement is the property of hardened cement paste undergoing large change in volume after setting without delayed destructive expansion. This destructive expansion is caused by excessive am...

Square face of the brick is called as “header”. If all the bricks on the facing of the wall are placed as headers then the work is called Header Bond. Header bond is used for the construction of w...

TMT means Thermomechanical Treatment of steel. It’s a process of simultaneous application of heat and a deformation process of metal, in order to change its shape and refine the microstructure. Hot...

TMT: Thermo-Mechanicaly Treated Steel

Workability of concrete is one of the physical parameters of concrete which affects the strength and durability as well as the cost of labor and appearance of the finished product.

The ease with which the concrete can be transported,placed,compacted and finished is know as workability.
