SOIL AS A CONCRETE AGGREGATE

ERDREICH ALS BETONZUSCHLAGSTOFF

COARSE SAND 4 TO 7%, SAND 8 TO 12% AND CLAY 10 TO 16% BY WEIGHT OF DRY SOIL CONTENT ARE ADDED TO HYDROPHOBIC CEMENT FOR THE STABILIZATION OF SUBGRADE CROWNS AND FROST BLANKETS IN RAILWAY AND ROAD CONSTRUCTION AND FOR THE MANUFACTURE OF ROAD SURFACES FOR STREETS WITH LOW TRAFFIC LOADS. THE SOIL-CEMENT MIXTURE IS COMPACTED WITH VIBRATING ROLLERS AND SHOULD ACHIEVE A MINIMUM COMPRESSIVE STRENGTH OF 60 KP/CM2 AFTER 28 DAYS. HYDROPHOBIC CEMENT DOES NOT BEGIN TO SET UNTIL SOIL HAS BEEN ADDED. IT HAS A LOWER WATER REQUIREMENT THAN NORMAL CEMENT, IS RESISTANT TO FLUCTUATIONS IN THE PARTICLE DISTRIBUTION OF THE SOIL AND RENDERS THE COMPLETED PAVEMENT ADEQUATELY FROST RESISTANT.
