| Title of the article | Gypums-cement-pozzolanic binders with the use of ground thermoactivated clay and plasticizing additives |
| Abstract. | The work investigated the influence of different types of plasticizers on the strength characteristics, resistance to water and other basic physico-mechanical properties gypums-cement-pozzolanic binder with the use of powdered thermally activated clay as an active mineral additives. Studied chemical, mineral and granulometric composition of the original clay, set the parameters of the process of dehydration of clay. Supplements of Hyper-plasticizers Melflux 2651 F and Melflux PP 100 F, characterized by the presence of hydrophobic side chains, as a result of both electrostatic and steric effect, provide a more significant reduction in water demand and improving the physical and mechanical properties of the binder compared with additions of superplasticizer S-3 and Melment F10. Higher efficiency additives Melflux 2651 F, characterized by greater length of the side chains of polyester compared to Melflux PP 100 F, associated with an increase in steric effect, provides. Set the number of plasticizers that provide the greatest plasticizing effect, to increase the strength, water resistance of the gypums-cement-pozzolanic binder to the groups water-resistant binders. |
