Important Shrinkage Parameters in Soil Engineering
The important parameters related to shrinkage limit in soil engineering are shrinkage index, shrinkage limit, volumetric shrinkage, and linear shrinkage. Each parameter is briefly explained in this article. 1. Shrinkage Index ( Is ) The numerical difference between the liquid ...
Ferrocement Water Tank Construction and Uses
Water tanks made of ferrocement are used widely in many parts of the world to store water for domestic, stock, irrigation and industrial purposes. Ferrocement (also called as Ferro-concrete) consists of a cement-rich mortar applied on both sides of a ...
Floating Columns in Building Structures – Need and Uses
A column is a vertical member which transfers the loads from beam to foundation whereas a floating column is a vertical member which transfers the load from beam to another beam. The load transfer in any building is usually from ...
What is Soil Suction?
Soil suction is defined as the state of the soil when it is under reduced pressure. It is measured in terms of the height of the water column (h) suspended in the soil. The main features and factors affecting soil ...
How to Measure Soil Suction?
The suction in soil mass can be measured mainly by three methods namely Tensiometer method, Suction Plate method and Centrifuge Method. Each method is briefly explained below. 1. Tensiometer Method The figure-1 below shows the arrangement of tensiometer to determine ...
Determination of Water Content by Sand Bath Method
Sand bath method is a field method conducted to determine the water content of the soil. This method is fast but the result is not as accurate as the oven-dry method. Also Read: Determination of water content by oven dry ...
Seismic Dampers – Types, Working Mechanism, and Components
Damper systems are designed and manufactured to protect structural integrities, control structural damages, and to prevent injuries to the residents by absorbing seismic energy and reducing deformations in the structure. Seismic dampers permit the structure to resist severe input energy ...
Difference Between Reinforced Concrete (RC) and Steel Structures
Reinforced concrete structures and steel structures follow a similar load transfer method but they differ in several factors like material, construction, load carrying capacity, durability, etc. One of the important difference is that the former uses concrete and the latter ...
Requirements of High Performance Concrete
High performance concrete (HPC) is produced in order to meet several requirements which are crucial for the successful construction of buildings in special circumstances. The performance requirements of HPC may involve improvement of concrete placement and compaction without segregation, long-term ...
