Abstract

Population growth and the attributed increase in housing demand are the cause of an acute shortage of suitable land for construction. As such, it has become a business strategy in construction sector to find optimum solutions in terms of modification and improvement of inferior lands. One readily available solution to address this issue is decreasing the settlement of Strip footings and improving their load bearing capacity through embedding Cemented Zeolite pads underneath the Strip footings. Therefore, here, a series of small scale 1g model tests have been conducted with the aim of evaluating the behavior of the Strip footings reinforced with Zeolite-Cemented pad. For practical purposes, Babolsar sand (in dry and saturated conditions) has been selected as the case study. The pads are placed underneath the foundations and in direct contact with the sand. The results demonstrate that placing a pad with one third thickness of the foundation's leads to an increase in the bearing capacity of both dry and saturated conditions. This increase is in the range between 30% to 91% under the dry condition and between 23% to 67% under the saturated condition. Also, this reinforCement causes clear increase in settlement reduction ratio of the dry condition in the range between 35% to 60% and in the 29% to 49% range for the saturated condition.
