IMPROVEMENT OF LOCAL MATERIALS FOR USE IN CONSTRUCTION - SELMA CHALK

A LABORATORY STUDY WAS MADE TO DETERMINE THE FEASIBILITY OF USING SELMA CHALK /A MARL OF CRETACEOUS AGE/ AS A STABILIZING AGENT FOR A PLASTIC CLAY AND A SAND. STRENGTH AND ATTERBERG LIMIT TESTS WERE MADE ON SPECIMENS PREPARED FROM' SAND STABILIZED WITH CEMENT, WITH RAW CHALK REPLACING THE CEMENT IN INCREMENTS, CLAY STABILIZED WITH LIME, BURNT CHALK REPLACING THE LIME IN INCREMENTS, GYPSUM PLUS BURNED CHALK, BAUXITE PLUS VARIOUS PERCENTAGES OF RAW AND BURNED CHALK, CLAY STABILIZED WITH VARIOUS PERCENTAGES OF MIXTURES OF BURNT CHALK & BAUXITE. IT WAS CONCLUDED THAT' 1. RAW CHALK WAS NOT EFFECTIVE AS A REPLACEMENT FOR EITHER CEMENT OR LIME. 2. BURNING OF CHALK AND BAUXITE MIXTURES DID NOT PRODUCE AN EFFECTIVE SUBSTITUTE FOR CEMENT. 3. BURNING OF THE CHALK OR MIXTURES OF CHALK AND BAUXITE PRODUCED A LIME-LIKE MATERIAL THAT WAS MUCH LESS EFFECTIVE AS A STABILIZER THAN COMMERCIAL LIME, THE EFFECTIVENESS BEING MUCH LESS THAN THE RELATIVE PERCENTAGES OF CALCIUM HYDROXIDE WOULD INDICATE. /BPR/
