ORGANIC MATTER IN SOIL IN RELATION TO SOIL-CEMENT STABILIZATION

THE ACTIVE COMPOUNDS, ABOUT 0.2% BY WEIGHT OF THE SOIL, ARE PROBABLY LIGNIN-PROTEIN IN CHARACTER, THEIR HIGH ACTIVITY TOWARDS CEMENT ARISING FROM THEIR ABILITY TO ABSORB CALCIUM IONS. UNCONFINED COMPRESSION TESTS INDICATE THAT HARDENING OF THE STABILIZED SOIL IS DELAYED UNLESS ABOUT 0.25% OF CALCIUM CHLORIDE IS ADDED TO THE MIXTURE, OR SUPER-RAPID-HARDENING CEMENT (RAPID-HARDENING PORTLAND CEMENT PLUS 2% BY WEIGHT OF CALCIUM CHLORIDE) IS SUBSTITUTED FOR THE NORMAL CEMENT. ACID SOILS GIVE MOST TROUBLE IN THIS RESPECT.
