Title of the articleSAND 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.
Keywords.Specific surface area, dispersivity, vibratory compaction, structure formation, juvenile surface, SiOH- active group.
