Strip footing-
A strip footing is provided for a load bearing wall.
A strip footing is also provided for a row of column which are so closely spaced that their spread footing overlap or nearly touch each other. In such a case it is more economical to provide a strip footing than to provide a number of spread footing in one line.
A strip footing is also known as continuous footing.

Flash set is the stiffening of cement paste without strength development with high heat evaluation ( premature hardening)
Tri calcium aluminate reacts immediately with water and is responsible for flash set.
Plasticity can be regained with addition of water.
Gypsum is added to cement to reduce flash setting.
After flash set mixing is not allowed because no gain in strength development after mixing.
Note- False set is stiffening of paste without heat evolution. Remixing of paste without addition of water restores plasticity of the paste. Hence mixing is allowed.
Ans-(D) For wall, the plastering should be measured for whole face of the wall both side as solid and deduction for opening should be made in following manner. No deduction is made for the ends of beam, posts, rafters etc. For small opening upto 0.5 sq.m, no deduction is made and at the time no addiRead more

For wall, the plastering should be measured for whole face of the wall both side as solid and deduction for opening should be made in following manner.
No deduction is made for the ends of beam, posts, rafters etc.
For small opening upto 0.5 sq.m, no deduction is made and at the time no additions are made for jambs, soffits and sills of these opening.
For opening exceeding 0.5 sq.m but not exceeding 3 sq.m deduction is made for one side and other face is allowed for jambs soffits and sills which are not taken into account separately.
For opening above 3 sq.m deduction is made for both faces of the opening and the jambs, soffits and sills are into account and added.
Ans-(B) The ozone layer acts as a filter for UV-radiation from the sun therefore, this process serves as a protective shield to human life against the adverse effects of UV like burn and some types of skin cancer.

The ozone layer acts as a filter for UV-radiation from the sun therefore, this process serves as a protective shield to human life against the adverse effects of UV like burn and some types of skin cancer. It is obvious that any depletion of stratospheric ozone would be harmful to life on this earth.
Primary reason for ozone layer depletion is CFC ( Chlorofluoro carbon ) or freon.
Ans-(D) Cut back asphalts generally consist of about 85% asphalt cement and 15% cutter, by weight as well as by volume since, the specific gravity of asphalt is very close.

The river in alluvial plain may be broadly classified into the following three type.
Meandering type
Aggrading type
Degrading type
Meandering type-
The chief characteristics of these river reaches is the zig-zag fashion in which they flow.
This zig- zag fashion is called meandering.
They meander freely from one bank to another and carry sediment which is similar to bed material.
Materials gets eroded constantly from the outer edge of the bend and get deposited either on the inner edge of the successive bend or between two successive bends to form a bar.
When once a straight moving river slightly deviates from its axis, the unbalance created goes on multiplying with constant erosion from the outer edge and deposition on the inner edge. If unchecked, the process continuous, resulting in the formation of large meanders.
Ans-(D) Ogee spillway is least suitable for earthen dam as compared to chute spillway, side channel spillway and shaft spillway.
