| Title of the article | The effect of plasticizers on the thermal and viscous-plastic properties of silicate mixture for gas silicate |
| Abstract. | To improve the quality of cellular concrete is necessary to reduce the density of wall structures and still maintain a given level of quality. By reducing the density the number of defects of the microstructure increases. To increase the strength of the microstructure can be applied reducing water-solid relationship. However, the reduction of water-solid ratio silicate mixture leads to a mismatch of all processes. Rheology deviation from the optimal values is possible by plasticizers. There have been studies of plasticizers C-3, Glenium ACE 30 and GPM-G. The studies were conducted by studying the effect of plasticizers on the hydration of the lime in the system «CaO – H2O – plasticizer» as well as the complex parameters of a real silicate mixture: diameter spreading out of silicate mixture on the basis of Suttard viscosity and temperature of the mixture at the time of filling in the form. The features of plasticizers in the model and real systems were discovered. Their effective dosages were defined. The co-administration with other chemical additives was explored. The conclusions about the possibility of reducing the «water-solid» ratio and about implementation of compensation measures on the basis of plasticizers were made based on experimental data. |
