Optimum Mix Design for Self-Compacting Concrete Using Pulverized Fuel Ash as Cement Replacement Material

Since last one decade self-compacting concrete is gaining interest as niche research area
in advancement in concrete technology. This research study aimed to determine the mix
design for optimum rheological properties of self compacting concrete when using
pulverized fly ash as the cement replacement material. A number of trial mixes were
designed to determine the rheological properties using V -funnel and flow measurement
tests. The mixes that did comply with the specified rheological properties are to be tested
for strength and porosity, in order to assess their engineering properties and durability
characteristic. Under the optimal superplasticizer identified in this study (7kg!m\ adding
fly ash to the mix did not give much variation from the control mix (55Mpa for control
mix, 51Mpa for fly ash mix at 56-days), but the result for fly ash show high potential to
achieve higher strength at later age.
