In order to solve this situation, organic flocculants (typically polyacrylamides) are added to increase the affinity between the fibres and the inorganic particles. These flocculants induce particle aggregates (flocs), improving the retention at the primary sheet formation.,Polyacrylamide induced flocculation of a cement suspension … ,This paper shows that anionic PAM (A-PAM) are the most suitable to induce cement flocculation and to obtain optimal properties of the formed flocs. This is because the flocculation process is…,Polyacrylamide induced flocculation of a cement suspension … ,Abstract The use of cellulose, instead of asbestos, in the fibre cement composites manufacture, using the Hatschek process, reduces cement retention and makes necessary to use a flocculant which is crucial for the plant productivity. The use of different types and doses of polyacrylamides (PAM) as well as the addition process, have been studied to obtain an in-depth knowledge of floc properties.
