Optimisasi Bubuk Slag Nikel dengan Sistem Ternary C-A-S
Abstrak
This papers study concerning optimization of nickel slag powder as substitution material to partial cement by
C-A-S (CaO-Al2O3-SiO2) ternary system. Optimization conducted to determine procentage of nickel slag powder
in the consuming calcium hydroxide compound as hydration product of tricalcium silicate (C3S) and dicalcium
silicate (C2S) cement with water so that form secondary of calcium silicate hydrate (CSH) compound. By the
phase diagram C-A-S ternary system, procentage of optimum nickel slag powder determined by intersection
point between of balance line pozzolanic reaction and mixing line of material cement and nickel slag powder.
Analysis result indicate that by approach of C-A-S ternary system, percentage optimum of nickel slag powder is
14,59%.
