Application of Geopolymer Technology and Pile Raft Foundation in a Soil, Review Study

Abstract:

Foundation engineering has large challenges with weak and loose soil, especially sandy soil, which has low shear strength and high compressibility. as known used pile raft to reduced excessive settlement, differential settlement, and to increase bearing capacity of the soil to carrying the loads from super structure. The benefit of use combined (raft piles) to improved load distribution and, increase bearing capacity and enhance stability. It is depending upon many influencing factors the load distribution mechanisms, the pile number, the space between piles and on the pile position. Geopolymers are inorganic formed by the reaction of aluminosilicate materials with alkaline activator. To produce geopolymers, two essential conditions must be fulfilled: the presence of source material abundant in Silicon (Si) and Aluminium (Al), and the addition of an alkali activator, such as sodium/potassium hydroxide..it has several advantage than other traditional soil stabilization method, which increased the soil's load-bearing capacity, enhance the soil properties. This study aims to review the studies of previous researchers and their practical and theoretical findings regarding the use of geopolymers as stabilising agents and pile raft to improve the soil's resistance properties.
