You can measure a small land for construction with the help of measuring tape, but the same methodology can’t be applied to investigate a large area. Surveying is one of the fundamental subjects which helps you to kick start any project. Even though the result of surveying supports…

What is Sewage? Sewage is wastewater that is produced by people (domestic/municipal), which contains large amounts of water and other matters such as organic and inorganic impurities. The source of sewage might be from typical household water use, such as a bathroom, toilet, kitchen, and also by industries,…

As we all know, the column’s primary function is to transfer the load from the beam to the foundation. Here we are going to discuss the effective length. What is it? and how it differs for different types of columns. What is the length of the column? The…

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…

We all talk about the compressive strength of concrete all the time. And also know concrete is strong at compressive strength and weak at tensile strength. But what is meant by characteristic strength? What is the characteristic strength of concrete? The strength of concrete, where not more than…

You may have heard people debating about joining rivers across the nation for the welfare of Agriculture. Also, the usage of large canals (artificial waterways) to divert water from the mainstream river to urban areas. It’s not an easy task. To divert or utilize the natural stream by…

Now and then there will be a new boom of technology in every industry. Plastic Formwork is one of them in the construction industry like m sand replacing the river sand. What is Plastic Formwork? We are using traditional god materials such as timber & steel for formwork…

Is there any method being used to test the compressive strength of the concrete without destructing?  Yes, there is. The Rebound hammer test (Non-destructive test) is widely used to determine the compressive strength of the concrete elements, also called as Schmidt hammer test.  We have already discussed some…

What is the compaction factor test? The test used to find out the compaction factor (external force required) for a low workability concrete is known as the compaction factor test. It is conducted in the laboratory.  The compaction factor is the ratio between partially compacted to fully compacted…

Hope you know self-compacting concrete, which does not need any external force to settle properly over the structure. What is the Flow Table Test?  The Self-compacting concrete used where the reinforcement is congested and concrete compaction not possible by vibrator.  The test used to find out the fluidity…
