WETTING AND DRYING CYCLES EFFECT ON DURABILITY OF GYPSUM SOILS TREATED WITH CALCIUM CHLORIDE OR CEMENT ADDITIVES

| description | The study consists of two stages: the first one is to improve the gypsum soil with
cement or calcium chloride and the second stage is to expose these soil
specimens to series of wetting and drying cycles .Three soil specimens were
taken and marked as (A,B and C) with gypsum content (47, 32 and 23)%
respectively .The results show that cement additive increases the cohesion of soil
specimens to 50% and collapse potential decreases with 65% and soil specimens
improved with calcium chloride increase the cohesion up to more than 70% and
collapse potential decreased about 70%. In the first cycle for wetting and drying
cycles for soil specimens improved with cement the cohesion decreases about
25% and stays with the same ratio of the decreasing along the other cycle up to
twelfth cycle. Collapse potential remains with the same value and is not affected
by cycling of wetting and drying. In the first cycle for soil specimens treated with
calcium chloride there is no effect in the first cycle whereas in the fourth cycle
the cohesion increased by 60% and in the eighth cycle the cohesion decreased
8% and remains stable until the twelfth cycle. Collapse potential increases from
one cycle to another by (30-50) % for all soil specimens. |
