| Title of the article | SAND CONCRETE OF HIGH STRENGTH |
| Abstract. | A fine-grain high-impact concrete technology is developed which uses the no-addition portland cement not more than 310 kg per 1 concrete cubic metre providing the 85…94 МPa compression resistance and the 2326 kg per cubic metre solidity in air-dry conditions. The technology is based on application of the vibratory compaction and intends the usage of filled joint re-milling cement having a specific surface area of 500 square metre per kilo. The matrix material contains a finely dispersed quartz filler by the portland cement-to-filler ratio 1: 0.8…0.9. Physical and mechanical, physicotechnical characteristics, water curing and effect of temperature are examined. It is found out that the obtained quality characteristics of highly filled high-impact fine grain concrete are the result of mutual interaction between disperse particles of quartz filler and cement skin of matrix material in forming structure of fine grain concrete. |
