EVALUATION OF FRESH AND HARDENED PROPERTIES OF SCC BY PARTIAL REPLACEMENT OF CEMENT WITH EGG SHELL POWDER AND FINE AGGREGATE WITH FOUNDRY SAND

Abstract

The aim of this research is to know the behaviour and mechanical properties of self- 
compacting concrete after addition of industrial waste in different proportions. The experimental 
program is carried outby making use of this waste by-product can reduce the environmental 
problems and out to produce a low-cost and eco-friendly concrete.So as the researches has been 
done on this eggshell powder by partial replacement of cement in concrete with different 
percentages and concluded that it has increased the strength of concrete. Foundry sand is high 
quality silica sand used as a moulding material by ferrous and non-ferrous metal casting industries. 
Due to the improper disposal of this waste foundry sand causes environmental problems. Thus, by 
making use of this waste by-product can reduce the environmental problems.Natural sand will be 
replaced with waste foundry sand in different percentages like 0%, 20%, 30% and 40%and the 
cement with eggshell powder in the range of 0%, 2%, 4%, and5% for M-25 grade concrete.The 
standard cube specimens of 150 mm size will be casted with foundry sand and egg shell powder. The 
different tests on SCC will be performed to assess the properties such as L-Box test, U-Box test, V- 
Funnel test and slump test.From this experimental program the combination of eggshell powder 
with cement and natural sand with foundry sand we shall assess the strength of this blended 
concrete mix. The specimens will be tested for its 7days, 14days and 28 days compressive strength 
and split tensile strength, flexural strength and the results will be compared with test results of 
control specimens.
