The use of organic additives to improve microbial-induced carbonate precipitation (MICP) is a novel and innovative idea. This study is the first to address the effects of the cationic biopolymer polylysine (poly-Lys) on CaCO3 crystallization and sand solidification by MICP. CaCO3 was precipitated with and without poly-Lys by hydrolysis of urea by using ureolytic bacteria, Pararhodobacter sp
The effects of different types of anionic polyacrylamide (PAM) on crystallization behavior of precipitated calcium carbonate (PCC) prepared via carbonation using calcium hydroxide and carbon dioxide gas. The percentage of aragonite phase increased higher reaction temperature. The use of anionic PAM resulted in the formation of larger PCC aggregates than in the case of PCC crystallized without
