What are the alternate building blocks which can used in place of ordinary building stones and bricks?
Kuldeep Singh
A few alternative building block materials : Rammed earth blocks (heat and noise insulator, durable, fireproof) Mycelium blocks (organically self-healing making itself very durable, low maintenance, arguably the building blocks of future) Timbercrete blocks (lighter yet stronger and better insulatorRead more

What is the difference between Reinforced cement concrete and Fibre Reinforced Concrete?
Kuldeep Singh
Reinforced concrete is the kind of concrete you'll normally see. It's reinforced with steel rebars to compensate for the low tensile strength of plain concrete. Fiber reinforced concrete is one in which the steel rebars are replaced with fibrous material pre added into the concrete mix so as to haveRead more
Reinforced concrete is the kind of concrete you’ll normally see. It’s reinforced with steel rebars to compensate for the low tensile strength of plain concrete.
Fiber reinforced concrete is one in which the steel rebars are replaced with fibrous material pre added into the concrete mix so as to have this fibrous material embedded as reinforcement in the finished concrete. The fibres used vary from steel, plastic, synthetics, polymers, natural fibres and some more.

Kuldeep Singh
Well, if you're analyzing a beam, then the quickest and easiest way is hands down, the moment - area method. Students often overlook it and delve into complex methods while the problem may be solved a lot easily. Other than this, there are often other quick methods depending on the question.

Well, if you’re analyzing a beam, then the quickest and easiest way is hands down, the moment – area method. Students often overlook it and delve into complex methods while the problem may be solved a lot easily.
Other than this, there are often other quick methods depending on the question. For example sometimes the conjugate beam method is not such a bad choice. If you can write the moment curvature equation and are quick at differentiation, you can use that.
I for one, never get into slope deflection method unless it is strictly needed. I stick to moment area, conjugate beam and the 4th order differential equation.
Also, a friendly tip : just have a look at the options especially in the IES paper. They never push you into long calculations. You could sense that some options just have to be wrong and are nowhere close to be correct. In GATE, this approach doesn’t fare well though.
Hope it helps.

The expansion joints allow for easy movement of concrete slab edges when the concrete of the deck expands or contracts. As a result, the expansion joints prevent the he deck slabs from colliding and cracking, tension cracking and bending out of shape. The expansion can be thermal expansion due to seRead more
The expansion joints allow for easy movement of concrete slab edges when the concrete of the deck expands or contracts. As a result, the expansion joints prevent the he deck slabs from colliding and cracking, tension cracking and bending out of shape.
The expansion can be thermal expansion due to seasonal and weather changes and also, expansion due to traffic load on the slabs. The vehicle axles usually impose asymmetrical moments which cause differential bending at different slab edges. To keep the deck in original shape, expansion joints play an additional role.
Also, generally in concrete pavements, regular shaped cracks or cuts are deliberately introduced just after construction, so that the location of future cracks is fixed since the concrete is far more liable to crack where it’s already cracked. This cracked area is in turn additionally reinforced by the expansion joint steel and the future cracks are by restricted from spreading. This is the reason why the cracks are made at the edges only.

What are the various causes of providing a cavity wall?

The most important reason for providing cavity walls is thermal insulation. Cavity walls tend to resist heat in summers Summers and retain heat in the building during winters. They also help.in keeping the inside a bit drier as compared to solid wall buildings.
Also, cavity walls reduce their own weight onto the footings.
Cavity walls are used to expel rainwater by allowing a wind flow in the cavity and thus prevent damp.
They resist wind-driven rain.
They allow for cheaper insulation material to be used to the same effect as compared to normal masonry walls.
Sound insulation.
Economically cheaper than solid walls.
Outer efflorescence prevented.
A small advantage of better seismic performance.

Cadastral survey (also referred to as ‘Reki’) is part of the survey relating to land ownership and boundary markings. Basically, you need to hall out areas with different ownerships before laying complete authority to proceed with any project. The surveying activity for that is a Cadastral survey.
Sometimes, Cadastral surveys also include marking out of trees, pipelines, and other important details that need to be located before proceeding with any job on a given land.
