SOIL STABILIZATION WITH MIXED BINDERS

COMPARATIVE LABORATORY EXPERIMENTS ARE DESCRIBED REGARDING THE STABILIZATION OF VARIOUS TYPES OF SOIL WITH CEMENT, BUNA-LIME AND A MIXED BINDER BASED ON A LOW GRADE BLAST-FURNACE CEMENT. BESIDES CLEAN NON-BINDING AND ORGANICALLY UNCLEAN SOILS, A BINDING MATERIAL AND A CRUSHED SAND WERE TESTED. THE PRESSURE AND SPLITTING RESISTANCE WERE MEASURED ACCORDING TO THE AIR AND WATER CONTENT, AND A WET- DRY TEST, A FREEZING AND DEFROSTING TEST, AND A WEATHERING TEST. WITH NON-BINDING MATERIALS, LOW BUT SUFFICIENT DENSITIES WERE YIELDED AS COMPARED TO CEMENT STABILIZATION. VERY SILTY SOILS AND CRUSHED SAND REQUIRE A HIGHER CONTENT OF BINDING AGENTS, AND WITH SOILS WHICH ARE ORGANICALLY UNCLEAN, THE MIXED BINDER IS UNSUITABLE. NO DEFINITE CONNECTION BETWEEN THE STANDARD DENSITY OF THE MIXED BINDER AND THE DENSITY OF THE STABILIZATION WAS ESTABLISHED. THE SPEED OF HARDENING AND THE WEATHER RESISTANCE DEPEND ON THE REACTION OF THE BINDING AGENT WITH THE SOIL AND REQUIRE IN EACH CASE NEW SUITABILITY EXPERIMENTS. /FG/RRL/
