Reinforced soil is the combination of compacted earth fill with tensile reinforcement to create an earth structure. The properties and performance of this earth structure depend on the bonding between the soil and reinforcement. The layout of reinforcement is done between the layers of compacted earth fill, which is an essential part of the construction … Read more
Modular construction is a newly adopted method in the construction industry where the houses are constructed as rectangular blocks away from the actual construction site. It is also known as “Offsite Construction”. These blocks are then transported to the actual site and placed as per the architectural drawings. These building are made of prefabricated or … Read more
Factors affecting Compaction of soil Compaction of the soil is the process where the dry density of soil is increased by reducing air content or air voids present in the soil. This process is an essential part of the construction of any structure, as it strengthens the soil. Many factors influence the degree with which … Read more
Methods of Underwater Repair of Concrete Structures Underwater concrete structures are prone to damage due to many reasons. There are some methods which are specially adapted to repair these damages. Care should be taken to ensure that the damaged area is not contaminated before the application of the repair material. The material used for the … Read more
Characteristics of Good Building Stones Every building stone which is used for construction, cannot satisfy all the ideal requirements. For example, when the stone satisfies the requirement of strength and durability, it may not do the same with other necessities such as ease of dressing. Hence it is the job of the site engineer to … Read more
Sand Compaction Piles Sand compaction piles are one of the potential methods for improving ground stability, preventing liquefaction, reducing settlement and similar applications. This method involves driving a hollow steel pipe into the ground. The bottom is closed with a collapsible plate down to the required depth and then pipe is filled with sand. The … Read more
Vibro Stone Columns To improve the load bearing capacity of in-situ soils and fills, Vibro stone columns are designed and are used. These columns reduce the differential settlements of non-homogeneous and compressible soils which allows the use of shallow footings and thinner base slabs. For the construction of Vibro stone columns, the vibrator is made … Read more
Bentonite Slurry in civil engineering Bentonite slurry is a combination of sodium bentonite and slurry. A slurry is a thin sloppy mud or cement or, in extended use, any fluid mixture of a pulverized solid with water, often used as a convenient way of handling solids in bulk. This combination is frequently utilized to form a solid … Read more
Soil Pre-Compression Soil Pre-compression is one of the ground improvement technique which compresses the ground under an applied pressure before placing or completing the structural load. Pre-compression is performed in following two ways: Ground precompression is achieved by pre-loading, which requires placement and removal of earth, water, or some other dead load, before construction, similar … Read more
