Madeh Izat Hamakareem
Pile penetration ratio and chisel energy level are two methods that are used to decide on the termination of pile depth in the construction site: 1. Pile Penetration Ratio (PPR) for Rotary Piling Equation for the determination of pile termination point in construction site: PPR=(2⋅π⋅N⋅T⋅t)/(A⋅d) Read more
Pile penetration ratio and chisel energy level are two methods that are used to decide on the termination of pile depth in the construction site:
1. Pile Penetration Ratio (PPR) for Rotary Piling
Equation for the determination of pile termination point in construction site:
PPR=(2⋅π⋅N⋅T⋅t)/(A⋅d) Equation 1
PPR: Pile penetration ratio, kN m/m^2/ cm
N: RPM
T: Torque corresponding to RPM, kN.m
t: Time duration in minutes, normally 10 min
A: Pile cross-section area, m^2
D: Pile penetration, cm
2. Chiseling Energy Concept
Use the following expression to estimate the response of founding rock strata in terms of Energy Level:
E=(W⋅h⋅n⋅N)/(A⋅d) Equation 2
Where:
E: Chisel energy level, kN.m/m^2/cm
W: Weight of chisel, kN
h: Fall of the chisel in meters given in every blow (m)
n: Reduction factor, 0.8–1.0 based on likely drag on chisel due to slurry, submerged weight of chisel in high groundwater, winch rope friction, and type of muck (clayey or sandy), based on rock type.
N: No. of blows in the stipulated duration, usually half an hour
A: Nominal pile cross-sectional area, m^2
D: Penetration into the rock strata in that stipulated duration, cm

Madeh Izat Hamakareem
Carries a portion of flexural factored shear force. Restrict the growth of diagonal cracks. Hold the longitudinal reinforcement bars in place. Provide some confinement to the concrete in the compression zone if the stirrups are in forms of closed ties.

A fire brick is a special type of brick made using fire clay and has a good resistance against high temperatures which are used in kilns, lining furnaces, fireplaces, and fireboxes. These bricks are manufactured in a way similar to that of normal bricks, except during the burning process- Fire bricks are exposed to very high temperatures.

Madeh Izat Hamakareem
To improve the strength, elasticity, and durability properties. Seasoning of timber is the process by which moisture content in the timber is reduced to the required level. A well-seasoned timber has 15% moisture content in it. For more details, please visit the following link: https://theconstructRead more
