عنوان مقاله [English]
There are vast planes of quicksand in Iran that create many financial losses for the road and railroad projects implemented in these areas, as well as social and hygienic problems for the residents of these areas. Presently the surface area of deserted and sandy planes in the country is estimated as 34 MH and the deserted areas as 16 MH, amongst which 12 MH is the sandy areas and 5 MH of these areas is the place of quicksand. We are therefore confronted with vast sandy areas that result difficulties in construction of roads and railroads. In this research two types of pozzolanas with different silica and alumina contents have been used in stabilization process of sandy soils and the effect of silica and alumina on the ultimate compressive strength and curing time required for strength gain have been studied and the results are concluded in the paper.
