Concrete Slump Test - Definition, Types, Procedure
Concrete slump test is a simple and low-cost test which is prepared in the laboratory or at the construction site for the determination of workability and consistency. Slump Test provides immediate result about the consistency and workability of concrete, that is the reason it is used widely in all over the world since 1922.

Use of Prefabrication to Minimize Construction Waste - A
The manufacture, transportation and on-site assembly sectors of precast construction projects are often considered separately and managed by rule of thumb, causing an inefficient use of resources
Precast Concrete: Advantages and Disadvantages
In precast concrete construction method, structural elements are produced in manufacturing plants while other activities at the construction site proceed. When the structural elements are needed, they are immediately sent to the site and assembled continuously, forming the structural frame and enclosing the building.
Schmidt hammer test or Rebound Hammer test of Concrete
Rebound hammer test is a Non-destructive (NDT test of Concrete) and simple concrete test which is used to test the Compressive strength of concrete without any damage. Moreover, the best part of Rebound hammer test is concrete can be tested in real time at the site instead of going to the lab without any damage.
16 Different Types of Concrete - Home Stratosphere
Ready-mix concrete is the type of concrete manufactured in a factory and then delivered to the construction sites via trucks comprising of in-transit mixers.It is manufactured under controlled operations and transported and placed at sites using highly sophisticated vehicles and methods.
QUALITY CONTROL IN CONCRETE CONSTRUCTION WORK
Once the concrete is laid and compacted, compression tests are made on the cubes made out of this concrete. For ordinary concrete, cubes are made out of the concrete made at work site. The hardened concrete has to be checked for trueness in dimensions, shape and sizes as per design specification.
Bioconcrete: next generation of self-healing concrete
Concrete is one of the most widely used construction materials and has a high tendency to form cracks. These cracks lead to significant reduction in concrete service life and high replacement costs. Although it is not possible to prevent crack formation, various types of techniques are in place to heal the cracks. It has been shown that some of the current concrete treatment methods such as

Difference Between Pre-Tensioning and Post-Tensioning
This method is developed due to the bonding between the concrete and steel tendons. This method is developed due to bearing. 9. Pre-tensioning is preferred when the structural element is small and easy to transport. Post-tensioning is preferred when the structural element is heavy. 10.
Underpinning Methods, Procedure, Use in ... - Cement Concrete
Underpinning is a sensitive repair project so, we have to choose the correct method for it. For the correct method, we have to understand and judge the soil strata, the current situation, and problems concerning the entire foundation, the required depth, and extent of the new foundation.
What Is Modular Construction? | Modular Building Institute
GREENER. The factory-controlled process generates less waste, creates fewer site disturbances and allows for tighter construction. Greater Flexibility and Reuse: Modular buildings can be disassembled and the modules relocated or refurbished for new use, reducing the demand for raw materials and minimizing the amount of energy expended to create a building to meet the new need.

Methods of Transportation of Concrete - Dumpers, Trucks
Only the cement of top surface will contact with water, rest of the concrete will not contact with the water. The other method which can be used for mixing and can transport over a large distance is through "ready mixed concrete". This is very much used where the area is congested and one cannot mix the concrete on site.

What is Workability of Concrete? Types, Mechanism - Civil
Types, Mechanism. Workability is a property of raw or fresh concrete mixture. In simple words, workability means the ease of placement and workable concrete means the concrete which can be placed and can be compacted easily without any segregation. Workability is a vital property of concrete and related with compaction as well as strength.
