| Title of the article | Reduction of consumption of cement in self-compacting fine-grained concrete |
| Abstract. | The use of self-compacting concrete instead of the ordinary at present is very limited. Despite the high technological level, comprehensive economic efficiency, this material is not used due to its high cost of materials relative to ordinary concrete in 1,4-1,5 times. The price rises due to increased cost of cement. In the study the task of reducing the cost of cement in self-compacting concrete while maintaining the basic strength and performance of ordinary concrete. Thus, managed to develop a composition class B30 with the consumption of 300 kg, which is not inferior in strength properties to the composition with the consumption of 550 kg/m3. But to get such concrete requires the use of graded sand and the combination of limestone powder and silica fume. The reduction of cement consumption and addition of limestone powder helped to reduce the cost of self-compacting concrete, which invariably increases the interest of enterprises in the construction industry to the material. |
