Recently, a number of researches have involved
improving the concrete technology requirements through
advanced research. These studies involved high strength concrete
HSC, were highly dependent on the quality of ingredient–
materials. HSC production potentially involves several trial
mixes and uses high quantities of fine materials thus making it
very costly and time consuming. The objectives of this study were
to reduce the production cost, time required and to improve HSC
properties by providing control mixes and using fly ash as partial
cement replacement. This was done by experimentally
investigating the HSC production using 10%, 20% and 30%
replacement of cement by fly ash and selecting the optimum
replacement content. All concrete mixes were homogeneous in
fresh concrete state, did not show any sign of segregation and
maintains slump between 80-110mm. Fly ash addition further
improved the workability. At the age 90 days, all concrete mixes
achieved the cube compressive strength between 80 to 120MPa.
Tensile and flexural strength were increased using fly ash using
fly ash. Higher strength concrete showed low ductility because
the ultimate strain was found less than 0.35%, there was In
general 20% fly ash content was found the optimum. |
