What are the properties and significance of Fire Clay?
CB Sowmya
Properties and significance: It can withstand a temperature of at least 1515 °C. It is made up of 65% siliceous materials and 22% argillaceous materials. It has high alumina content and kaolinite. It is plastic in nature and have high iron impurities. It is ideal for lining surfaces exposed to highRead more

Vivek Patel
Prandtl mixing line theory is the phenomenon of momentum remaining constant in fluid flow where the boundary layer is a theory of variations of velocity perpendicular to the floor and velocity value change from 0 to infinite. Prandtl mixing theory is used for the study of momentum in fluid flow. BouRead more
Prandtl mixing line theory is the phenomenon of momentum remaining constant in fluid flow where the boundary layer is a theory of variations of velocity perpendicular to the floor and velocity value change from 0 to infinite.
Prandtl mixing theory is used for the study of momentum in fluid flow.
Boundary layer theory is used for the study of velocity distributions in fluid flow.

See lessWhat is the bearing capacity of soil? How can we calculate it?
Vivek Patel
The bearing capacity means the soil can transfer the load safely from the foundation to the soil strata without excessive settlement and without any type of failure. Soil bearing capacity can be identify by some test: Dynamic cone penitration test Static cone penitration test Plate load test CBR tesRead more
The bearing capacity means the soil can transfer the load safely from the foundation to the soil strata without excessive settlement and without any type of failure.
Soil bearing capacity can be identify by some test:
Those all test are conducted at site to identify soil bearing capacity.
Two criteria majorly accounted for foundation failure
- Excessive settlement and relative settlement
- Shear failure of soil (punching failure, local shear failure and general shear failure)

Abbas Khan Civil Engineer
The zero Air Void line is obtained when there is no presence of the air in the pores of a soil mass and totally filled with the water and soil mass get saturated. It is determined by the compaction test of a soil. Draw the graph between Dry Density VS water content, calculate the dry density from thRead more

It is determined by the compaction test of a soil. Draw the graph between Dry Density VS water content, calculate the dry density from the compaction test results, and Zero Air void line is drawn on the graph.

See lessWhat is the meaning of shear strength in soil?
Vivek Patel
Shear strength of soil is resistance against shear come from the footing of structure. Shear strength gives soil bearing capacity of structure footing without excessive settlement. Shear strength of soil is given by coulomb. Shear strength = c +φ tan ∅ Where c= cohesion φ= normal stress ∅ = aRead more
Shear strength of soil is resistance against shear come from the footing of structure.
Shear strength gives soil bearing capacity of structure footing without excessive settlement.
Shear strength of soil is given by coulomb.
Shear strength = c +φ tan ∅
Where c= cohesion
φ= normal stress
∅ = angle of internal friction of soil
In clay angle of internal friction is very less and in sandy soil, cohesion is very less.
Some of the test is use for finding out shear strength of soil like

Kuldeep Singh
Earth pressure at rest is used for the design of underground structures, be abutments, etc. because it is expected that there would be no lateral displacement in the soil mass after construction is complete and during the life of the structure. Also, if you test the earth pressure in the field arounRead more
Earth pressure at rest is used for the design of underground structures, be abutments, etc. because it is expected that there would be no lateral displacement in the soil mass after construction is complete and during the life of the structure.
Also, if you test the earth pressure in the field around these structures, it matches very well with the calculated earth pressure at rest for normally consolidated soils.
