Evaluation ofMechanical Properties of Lightweight Self Compacting Low Cement Concrete Atefeh Zibanejad a zibanejad@cv iut ac ir June 2015 Department of Civil Engineering Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiSupervisor eft@cc iut ac irAbstractDue to weakness of constructing performances low efficient human resources and countries seismicitycondition reducing weight and increasing quality of concrete structures seems to be necessary Thus usinglightweight aggregate and self compacting concrete could be considered as an appropriate solution So far due to numerous advantages of self compacting concrete extensive researches have been done on it Butnevertheless small portion of those researches has been devoted to lightweight self compacting concrete SCLC Therefore better understanding of SCLC in fresh and hardened state was an objective of this thesis Production of Portland cement and essential constituent of concrete leads to the release significant amountof CO2 one ton of Portland cement clinker production is said to create approximately one ton of CO2 andother greenhouse gases so use of natural Pozzolans GGBS silica fume and limestone and other similarPozzolanic materials can reduce the use manufactures Portland cement clinker and at the same time reduceconcrete that is more durable In this thesis limestone GGBS and silica fume are used instead of somePortland cement The combination of the advantages of reducing amount of cement in concrete lightweightconcrete and self compacting concrete is the purpose of this thesis In this research 57 experiments oflightweight self compacting have been carried out In the concrete fresh state slump flow with T500 and V Funnel are used for evaluating self compatibility criteria In studying test performances it has been foundthat suitable range of V Funnel for identify self compatibility were observed different from SCC withregular aggregates In concrete hardened state parameters as compressive strength at age of 7 28 and in some items 90 dayswere studied as experiments output Replacement of GGBS and limestone up to desired viscosity leads toincreasing compressive strength of concrete Key Words
