The aggregates are classified based on shape, size, density, Geographical Origin. We have discussed the same in detail on the classification of aggregates. Based on their transportation and origin, they are classified as transported soil and residual soil. What is transported soil and residual soil? The deposited soil transported from…
You are all aware that aggregates occupy 70 to 80% of the total volume of concrete. The fine aggregates are used as filler material & the coarse aggregate are used in concrete to increase the compressive strength of the concrete. The size of the aggregates influences the bondage of the…
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 of bitumen?…
Earlier, we had discussed the penetration test of bitumen to find out the consistency or hardness, grade the bitumen for the construction work. In this, we are going to test the softening point of bitumen. The softening point test used to determine the melting point in which the bitumen reaches…
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 energy resource.…
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 in detail…
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 banks. However,…
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. Origin of…
The river sand is one inevitable material used in construction. It is used almost all stages of construction. Take it right from the foundation you will need them almost at every stage, Be it plastering, concrete & also as a filling material. But due to the high demand for river…
