  Situ concrete piles, are the most widely used type of deep foundation. In Iran experience shows, that technical problems and economic performance by avoiding the use of ordinary concrete with a slump an extremely high in these types of candles. Poor and low compress resistance, durability and high water permeability in the subsurface environment, the effects of this type of concrete planning. The excellent strength, permeability to ensure proper compaction, concrete ‌ ease and speed up the planning run, the significant advantages of self-compacting concrete. These benefits are especially situ concrete pile planning, most appear to be. In This paper compares core strength situ by taking samples from two typical arrangement of pile ordinary and self-compacting concrete and important results have been obtained. The core samples, to a depth of 14 m in which different levels of ground benchmark are tested show that the use of self-compacting concrete has technical  and economical advantages, and notable administrative lead to greater uniformity in resistance acquisition, located in the upper part of the pile is. This section, the maximum stresses due to vertical and lateral loads. Therefore, the use of self-compacting concrete in deep foundations, can widely replace traditional methods. Manuscript profile
