EVALUTION OF STRENGTH PARAMETERS ON PARTIAL REPLACEMENT OF CEMENT WITH DOLOMITE POWDER & FINE AGGREGATE WITH SUGARCANE BAGGASE ASH

Abstract

The purpose of this experiment is, to raise the strength of the M30 grade concrete mix. 
The compressive strength, split tensile strength and flexure strength shall be compared with those of 
the reference specimen and this paper inspects the possible results of using dolomite powder in 
partial replacement of cement and sugarcane bagasse ash in replacement of fine aggregate. 
Dolomite powder is acquired by grinding the sedimentary rock and it is preferred as the 
constructional material because of its higher density, for producing cement with dolomite powder, 
finely grounded dolomite was used as the cementatious material and in this experiment the partial 
replacement percentage of dolomite is 0%, 5%, 7.5%, 10%, 15%. 
The recent researches are experiencing agricultural and industrial wastes as a source of raw 
materials for the construction & the utilization of waste would be economical. Sugarcane baggase 
has been classified as the fibrous waste outcome from sugarcane in Sugar refining Industries. In this 
evaluation, sugarcane bagasse ash is partially replaced with fine aggregate and the percentages are 
0%, 10%, 20%, 30% and 40%. This bagasse ash mainly contains aluminium and silica. By the both 
combinations of Dolomite powder and SCBA we have got the good results up to 5% ,10% 
replacements. Flexural strength decreases with the increasing of dolomite powder percentages.
