This study was to investigate the reduction of hydration heat by utilizing industrial by-products
such as BFS(Blast Furnace Slag) and FA(Fly Ash). DM(Dredged Mud) was used by parent soil and
Ordinary portland cement was used by cementing material. Additives added to reduce the heat of
hydration were BFS and FA. From the results of experiment, hydration heat was decreased in
accordance with the addition of BFS and FA. The reason was that surface of BFS coated with
aluminosulfate and FA is apt to uptake free Ca2+ ion, which has not created a nucleus of Ca(OH)2.
Initial uniaxial strength was low, neither was not long term uniaxial strength. It was concluded
that silica rich layer(H2SiO4
4-) in solid phase early in the reaction of hydration was difficultly
moved in liquid phase due to the increase of ZP(Zeta Potential). However, the ZP in the later
hydration was decreased due to the acceleration of mobility of silica rich layer(H2SiO4
4-). Therefore,
long term physical properties such as uniaxial strength revealed.
