Abstract

This paper experimentally analyzes the effect of organic-additive on slurry thickening-time.
Moreover, this study introduces a new organic-additive from Durian's Skin -waste (DSW) material, as a
replacement additive for common Carboxymethyl-Cellulose (CMC) compound. The various process
contains de-lignification, chemical bleaching, grinding, and sieving is performed to obtain pure DSW
additive. DSW additive is then mixed with the cement and water to form a slurry sample and tested under
setting test procedures to obtain thickening time for each sample. The experiment result shows that higher
thickening time is observed for a slurry sample with a high DSW concentration. The temperature effect
indicates a short thickening time of the slurry sample. The utilization of organic additive from DSW is
effective for increasing slurry thickening time, means that the possibility to produce local additive is still
open.
