THE USE OF RESIDUE LEFT AFTER CURSHING IN QUARRIES IN ROAD CONSTRUCTION /IN RUSSIAN/

RESULTS OF INVESTIGATIONS INTO THE PETROGRAPHIC, CHEMICAL, AND PHYSICOCHEMICAL PROPERTIES OF CRUSHED STONE SAND OBTAINED FROM VOLCANIC ROCK IN FINE CRUSHING PLANTS IN THE UKRAINE ARE PRESENTED. THIS TYPE OF SAND IS EITHER FLAT OR ANGULAR IN SHAPE, CONTAINS 10 TO 17 PER CENT OF CLAYEY-SILT (0.46 TO 2.80 PER CENT CLAY), AND CAN ONLY BE USED IN ROAD CONSTRUCTION IF TREATED. EXPERIMENTAL RESULTS ARE GIVEN SHOWING THE POSSIBLE USE OF CRUSHED STONE SAND IN PAVEMENT LAYERS, IN CONCRETE, ASPHALTIC CONCRETE, AND RAILWAY BALLAST. CRUSHED STONE SAND CAN BE USED IN CONCRETE IF MIXED WITH NATURAL SAND. THE GRADING OF CRUSHED STONE SAND/NATURAL SAND MIXTURES MUST COMPLY WITH GOST SPECIFICATIONS 10.268-62 FOR FINE AGGREGATES. IF PART OF THE FINE NATURAL SAND IN CONCRETE IS REPLACED BY COARSE CRUSHED STONE SAND, THE MECHANICAL STRENGTH OF 28-DAY-OLD CONCRETE INCREASES BY 10 TO 20 PER CENT. THE ECONOMIC ASPECT OF THE USE OF CRUSHED STONE SAND IS CONSIDERED. /LCPC/RRL/
