摘要: Abstract A new method for the consolidation of loose sand formations has been developed. The involves in situ precipitation a composite calcium phosphate–polyelectrolyte salt that binds together with grains, thus resulting to their consolidation. Three different polyelectrolytes (PE) were tested, i.e., polyacrylic acid (PAA), polyallylamine hydrochloride (PAH), and polyethylenimine (PEI). effect PE tested on thermodynamics kinetics phosphate salts was investigated. types experiments done. Investigation adsorption either hydroxyapatite (Ca5(PO4)3OH, HAP) crystals or grains. Measurement heterogeneous nucleation HAP solid substrates mechanical properties obtained batch low high supersaturation solutions, respectively. Evaluation packs order investigate effectiveness method. crystallization rates, Rp, presence found R p PAA > PEI PAH , while crystal growth silicate took place only absence adsorbed PE. favored strongly process, whereas resulted formation poorly consolidated grain agglomerates.
