ABSTRACT
OBIE FAROBIE. Utilization of Glycerol Derived from Biodiesel Production as A
Cement Grinding Aid. Under supervision of LATIFAH K. DARUSMAN and
SUMINAR S. ACHMADI.
For the last few years, biodiesel industry in Indonesia has been growing
rapidly to overcome the increasing energy needs in the future. Biodiesel
production results in glycerol production as it is the main by-product in biodiesel
industry. One of the utilization of glycerol obtained from biodiesel production is
as a cement grinding aid (CGA). CGAs are organic substances added into the mill
at low dosage to inhibit agglomeration process and reduce particle size of cement.
This research was conducted in four stages, namely purification of crude glycerol,
characterization of crude and pure glycerol, synthesis of CGA under various
temperatures and triethanolamine (TEA) compositions, and characterization of
products using blaine specific surface area (BSS) and residue test. The results
showed that crude glycerol content was 40,19% whereas pure glycerol content
was 82,15%. BSS value of the cement with CGA supplementation was higher
than that of unsupplemented cement (blank) indicating that CGA-supplemented
cement had higher fineness than the unsupplemented cement. It was also found
that pure glycerol 95% and TEA 5% at 80ºC was the optimum CGA used to result
in finest cement with the BSS value of 4.836 cm2/g. Analysis of variance showed
that TEA composition, temperature of reaction, and the interactions gave
significant effects (P
