What is the difference between Tar and Bitumen?
Abbas Khan Civil Engineer
Bitumen; BITUMEN is a petroleum product formed by the process of distillation of crude petroleum. It is available both in solid and liquid form. It is providing a good grip to the tyres as compared to the coal tar. Bitumen is available in three types that is; Rapid Setting, Slow Setting and Medium sRead more
Bitumen;
BITUMEN is a petroleum product formed by the process of distillation of crude petroleum. It is available both in solid and liquid form. It is providing a good grip to the tyres as compared to the coal tar. Bitumen is available in three types that is; Rapid Setting, Slow Setting and Medium setting. In the modern era, we used bitumen instead of Coal Tar because Coal Tar is Carcinogenic.
COAL TAR; Coal tar is derived from the coal.It is a black viscous liquid used as a sealing agent in old roads making all over the world. It is not used in the current era, due to the carcinogenic product. It is produced through the process of destructive distillation in the absence of air. Coal Tar not provide enough grip to the tyres of the vehicle and heat up quickly causes wearing out of tyres.

Abbas Khan Civil Engineer
We can reduce the emission of gases in the construction industry by applying the following steps; 1- By implementing smart and efficient materials which are more durable and cheap. Also, it causes less pollution while they are manufacturing in the factory. 2- Eliminating material waste on the designRead more
We can reduce the emission of gases in the construction industry by applying the following steps;
1- By implementing smart and efficient materials which are more durable and cheap. Also, it causes less pollution while they are manufacturing in the factory.
2- Eliminating material waste on the design stage could decrease the emission of gases by 18% in the atmosphere.
3- Finding alternative material to the cement and steel in the construction industry for the construction of buildings and other structures because only cement contributes 32% of all the emissions in the world from material consumption.
4- Giving subsidies and tax-exemption for those eco-friendly buildings which are environment-friendly and sustainable use materials like bamboo are used.
5- Reusing building material and waste in a creative way to build new houses and flats is a step which also helps in the reduction of global gases.

Abbas Khan Civil Engineer
Cement GEL; The Cement Gel in a cement is a Calcium Silicate Hydrate ( CSH), which is responsible for the strength and binding in the structures. It is produced when a hydration reaction occurs by mixing water and cement; the paste is formed is called as cement gel.

See lessWhat is Sand Face Plaster and Where is it used?
Abbas Khan Civil Engineer
Sand Face Plaster; Sand face plaster is a layer of a cement-sand mortar applied over bricks. This type of plaster is used to give a smooth and appealing finishing touch to surfaces like walls and ceilings. It is used as a damp proof course on a masonry foundation to stop the moisture entering insideRead 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 lessIn construction Project, What is the meaning of the term Float?
Abbas Khan Civil Engineer
In Construction Management or Project management, the float is an amount of a time an activity can be delayed without having a subsequent effect on the other activities and delayed in the project completion date. Total float is directly related to the path.

See lessWhat are the benefits of T-beam in building compare to the ordinary beam?
Abbas Khan Civil Engineer
benefits Of T-Beam; 1- T beams have greater second moment of inertia as compared to the ordinary beams, so they have greater ability to resist bending effectively. The distribution of the material mass in the T-beam is consist of Flanges and web. Flanges are more effective in resisting bending stresRead more
benefits Of T-Beam;
1- T beams have greater second moment of inertia as compared to the ordinary beams, so they have greater ability to resist bending effectively.
The distribution of the material mass in the T-beam is consist of Flanges and web. Flanges are more effective in resisting bending stresses while the Web is more resistive in shear stresses.
2- The T-beam has separate parts for resisting both bending and shear forces as a result very good in resisting stresses as compared to ordinary rectangular beams in buildings and bridges.
