| Title of the article | Research Portland cement with the modified zeolite-containing additive |
| Abstract. | This paper considers the possibility of improvement of Portland cement quality by addition the zeolite-containing siliceous rock. Before use the zeolite-containing siliceous rock has been activated at the electro mass classificator. The thermogravimetric analysis methods were applied to studying of influence of additives on hydration process. Also standard techniques were applied for definition strength characteristics. The results of experiments have shown, that activation of zeolite-containing siliceous rock at the electro mass classificator allows to increase output of the finely dispersed fractions. Applying of additive on its basis improves strength properties of Portland cement. Brend of Portland cements raises from 300 to 500 and from 400 to 550. The improving the compressive strength is accompanied by some reduction of portlandite content in a cement stone. It is explained by the occurrence of chemical reactions between components of the additive and portlandite as a result of that is formed badly soluble and stronger hydrosilicate. The methods of the thermal analysis allow to control the hydration processes. |
