SELF COMPACTING CONCRETE

 


Self-compacting concrete also known as self-consolidating concrete.

It is one of the most widely used concrete types, mainly because of its self-compacting characteristics and strength.


SCC is a highly flowable, non-segregating, special concrete type that can settle into formworks, by means of its own weight.


SCC does not require compaction using external force from mechanical equipment such as immersion vibrators.


SCC was developed in Japan in 1980s in order to achieve high-performance durable concrete structures, and with advancements in concrete technology its use has become widespread all over the world.


The advantages of SCC in its fresh and hardened states include economic efficiency, improvement in working and living environment.


Compared with ordinary concrete, SCC includes large amounts of binder, super plasticizer, and/or viscosity modifying admixtures.

 

The placement of SCC is faster and requires less labour.

The appearance (surface finish), mechanical performance and durability of SCC can be considerably better than traditional concrete.

For conventional concrete, noise and vibration are generated when the vibrators are being operated with noise levels sometimes exceeding 100 dB.

use of SCC can lower the noise exposure on and around the construction site to approximately one-tenth of the noise level produced when traditionally vibrated concrete is used.

The reduction of noise levels will also improve the psychological working environment, improving internal communication at the site or the plant and providing less stressful surroundings, which again increases the health and safety for the workers.

NOTCHES AND WEIRs

Image
   NOTCH ,WEIR AND ITS TYPES Notch A  notch  may be defined as an obstruction over which the flow of liquid occurs   In case of measuring tank or reservoir, the opening is provided at the side of the tank such that the liquid surface in the tank is below the top edge of the opening. Weir A  weir  is a notch on a large scale used for measuring the flow of a river, canal etc. It is a concrete or masonry structure of substantial breadth built across the river in the direction of flow. This allows the excess water to flow over its entire length to the downstream side. Thus a weir is similar to a small dam constructed across the river, with a difference that the excess water flows downstream only through a small portion called  spillway  and in case of weir, the excess water flows over its entire length. Nappe and crest The sheet of water flowing through a notch or over a weir is known as  nappe  or  vein . The bott...

THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS

 THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS The Basics of Rebar If you have ever wondered what gives strength and stability to the concrete structures that we see around us, the answer is (most commonly) rebar. Rebar, short for reinforcing bar, is the steel rods that are embedded in concrete that provide tensile strength to what is actually and prevent cracking. Rebar comes in different shapes and sizes, but the most common type is deformed steel rebar, which has ridges or indentations along its surface to create a better bond with the concrete. Deformed steel rebar has been used in the construction industry for over a century, and it has revolutionised the way we build. With rebar, and using elements such as beams,  beam ties , rebar mesh, and reinforced walls, we can create taller, stronger, and more durable structures that can withstand natural disasters, environmental changes, and human activities. Some of the most iconic buildings in the world, such as...

What are different diameters of steel used in construction field?

         In the construction industry, the appropriate selection of materials is crucial as they form            the fundamental basis for determining the strength and durability of structures. TMT (Thermo-Mechanically Treated) Steel is one of the essential components in construction as it stands out for its exceptional strength and ductility in building structures. Thus, contributing to the prolonged longevity and durability of the structures. In this article, we will delve into the different sizes of  TMT steel bars  and their different uses in the construction industry. These TMT Steel bars come in different sizes based on their varied diameters. The different diameter of steel bars are as follows: 8mm Steel Rod 10mm Steel Rod 12mm Steel Rod 16mm Steel Rod 20mm Steel Rod 25mm Steel Rod 32mm Steel Rod, etc TMT bars of varied sizes, play a pivotal role in diverse infrastructure initiatives, the versatility of TMT bars is ...
