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…
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…
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…
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…
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…
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.…
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…
The test used to find out the workability of freshly mixed concrete by the consistometer apparatus is known as Vee Bee Test. Principles of Vee Bee Test Vee bee test is conducted at the laboratory. This test gives results based on the mobility and compatibility of the concrete.…
We all know the strength of concrete depends upon many factors such as properties of construction material, Mix Ratio & Working conditions. Workability of concrete is face value for all these factors. A single value that indicates the overall strength of concrete. Here we are going to discuss…
