88 Investigation of the effect of blast furnace slag on the mechanical properties and durability of roller compact concrete pavement in freezing regions Mohsen Shamsaddini m shamsaddini@cv iut ac ir May1 2019 Department of Civil Engineering Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiSupervisor Dr Madhkhan Morteza madhkhan@cc iut ac irAbstractThe roller compacted concrete is a rugged pavement that should be able to withstandthe traffic loads which are applied to it and like other concrete are in danger of beingdamaged The roller compacted concrete is more likely to be used in areas whereexcessive load or high tensions are imposed on the pavement In this case themechanical and durability parameters are of great importance In this research themechanical performance of concrete with cement type 2 was investigated by replacing0 20 40 and 60 of slag powder with a cement as a cementitious material andreplacing slag of high furnace with calcium carbonate powder as part of fine grainedused The mechanical strength parameters performed include compressive strength Brazilian tensile strength test and four point bending strength The specimens wereinclude compressive specimens in three ages 7 28 and 90 days 72 specimens of cubic150 150 150 mm and flexural specimens 48 specimens of 350 100 100 mm andBrezilian tensile speciment 48 specimens of 300 150 mm as well as for 150 and 300cycles of freezing and thawing 24 specimens of 150 150 150 mm and 24 specimensof 350 100 100 mm and for water absorption of 28 days 48 cubic samples of150 150 150 mm and salt scalling 48 specimens of 350 200 100 mm The resultsof this study show that with the replacement of 20 of the slag powder at the age of 7 28 and 90 days has the highest compressive strength which is about 50 higher thanconventional roller compacted concrete The Brazilian tensile strength and rupturemodules of the specimens made at the age of 28 and 90 days were measured byreplacing 20 and 40 of the slag powder with the cement increasing the tensile
