Abstract
The most important material which is used for the construction of any concrete structure is concrete itself. It is considered to be as a versatile construction material as its properties can be changed by various means, with the help of different elements and as and when required. Rheodynamic Concrete or Self-Compacting Concrete is a special form of concrete which can easily flow into any kind of formwork uniformly, without facing the problem of bleeding and segregation, gives a better finish, has a great characteristic of placement, requires no vibration, and thus gives a safe working environment. Due to a number of merits, this type of concrete had becoming popular in the construction work. Simultaneously, the big industries across the world are producing the by products such as fly ash, rice husk ash, etc. Thus, this paper represents a review, which is done to incorporate these wastes by – products in Self-Compacting Concrete and observe, how the different properties of the same has been modified effectively and efficiently.
Highlights
For most manmade constructions, concrete is widely used
Rice Husk Ash: Rice Husk Ash (RHA) is an agricultural waste product that is being produced in large quantities globally every year and there is a difficulty involved in its disposal
Even though the addition of Bond improving admixture causes the change in the properties of Self - Compacting Concrete (SCC), it was found that the if polyolefin fibres of 10 kg/m3 added in SCC, the strength in compression was measured 37 MPa and, which decreased to 35.5 MPa for the concrete mix which was made up by adding bond improving admixture, which may be a result of high amount of fibres and lesser compaction
Summary
Fine aggregates, coarse aggregates and sometimes admixtures, in some required proportions, it is made into use This mixture of cement aggregates and water is placed in different types of form and allows curing so as to get a hard – rock like substance, known as concrete. There are three different methods through which Self – Compacting Concrete can be made: 1. VMA method includes the use of Viscosity Modifying Admixtures. Combined methods include both increasing the proportion of powder content and using Viscosity Modifying Admixtures. The application of these methods depends upon various factors such as availability of materials, constructional conditions, etc. The applications of SCC in present world is limited because of inadequate standard mix-design procedure and methods of testing.
