What is a gravity dam? A structure that is constructed in such a way that its own (self) weight of the material is used to resist the external force (pressure) created by the water and other materials is known as gravity dam. It is constructed either by concrete…
The concrete is a macro content that is made by blending cement, sand & coarse aggregate with water. The strength of the structure depends on the properties of the concrete we use. In general, the concrete that we made at site or in RMC is suitable for general…
All of you are aware that the bitumen is a by-product material of petroleum which is mainly used for road construction work & other miscellaneous work. We are going to discuss the test, which is useful to grade the bitumen-based on its consistency. What is the penetration test…
The highway plays a vital role in the country’s economic growth by connecting people and transporting goods. We may unaware of many implementations that the experts used for our safety while we are on the road. One of them is Super Elevation. The term super elevation denoted in…
Every material usage by the urban population affects nature and makes scarcity. For example, take petroleum. It takes quite a long time to get crude oil likely 50 million years. In just 50 years we are going to run out of it. So humanity is moving to another…
The development of any particular area depends on the transportation facility of that area. Road transport plays an important role in the country’s infrastructural development. Likewise, the coarse aggregate used in road structure plays a vital part in its strength. We have already discussed the classification of aggregates earlier…
As we all know, the reason behind using reinforcement in concrete. Recap – The concrete is strong against compressive force & weak against tensile force. So we use reinforcement bars to increase its tensile strength. The reinforced concrete is used in construction because of excellent durability, workability &…
The sand is an inevitable material in construction which is used in almost every activity such as concrete, plastering, PCC, backfilling, earth embankment & many other works. The river sand naturally deposits in the riverbank, formed over many decades from the rock disintegrated and deposits on the river…
The aggregates are inevitable materials that are mixed with other binding materials in fixed proportions to make concrete in construction. Aggregates are the building blocks of concrete. If you calculate the required material for concrete, the fine & coarse aggregates will occupy 70 to 80% of its volume.…
