Compressive Strength and Elastic Properties of Self-Compacting Concrete Using Microwave-Incinerated Rice Husk Ash and Pulverized Fly Ash

Self-compacting concrete (SCC) is on average a new kind of high performance concrete that
sees the increase the workability and rate of flow with the addition of a superplasticiser. By its
very nature, SCC achieves compaction by means of its own weight into the every part of the
mould or formwork without segregation of coarse aggregation. Mechanical properties of
hardened SCC are considered to be the same as those of OPC concrete of the same W/B
(water-to-binder ratio). SCC usually produces greater high-performance properties such as
nigh strength and durability. Improved working environment, faster construction, less remedial
work, and increasing overall productivity are the benefits to the construction industry from the
utilization of self-compacting. Rice husk is one of the bulky wastes which are abundantly
available everywhere in the world at no cost.
Microwave burning to produce MIRHA will convert it into much value for use in
concrete as a partial cement replacement material at very low cost. During to the controlled
process of burning, emission of greenhouse gases to the environment is eliminated. The study
of this report is to evaluate the tensile and compressive strengths of the Self-compacting
concrete with the incorporation of Microwave Incinerated Rice Husk Ash (MIRHA) and
Pulverized Fly Ash (PFA). Due to the varying strength of concrete with the incorporation of
RHA and PFA, the compressive strength will be observed in 3,7,28 and 90 days. The tensile
strength and modulus of elasticity are to be evaluated to evaluate the elastic behaviour of SCC
