Adding fiber into soil-cement can improve its compressive and tensile strength. In engineering application, meet the requirements of mechanical properties economic cost by adding a certain proportion fiber, which has great significance for ensuring quality, reducing increasing efficiency. order to reflect strength characteristics mixed with performance constrained lateral deformation, unconfine...

This paper presents a new model for predicting the compressive strength of steel-confined concrete on circular concrete filled steel tube (CCFST) stub columns under axial loading condition based on Artificial Neural Networks (ANNs) by using a large wide of experimental investigations. The input parameters were selected based on past studies such as outer diameter of column, compressive strength...

This paper discusses the problem of clay shale in construction and need for its improvement. The use geopolymer as a sustainable environmentally friendly solution soil stabilization is presented an alternative to cement-based stabilization. Geopolymers are inorganic aluminum-silicates formed by silicon aluminum can be easily found materials such fly ash mixed with sodium hydroxide silicate. suc...

Geopolymer cement was evaluated as wellbore sealing material for carbon dioxide geosequestration application. Curing of cement system in saline water and strength testing in triaxial stress state condition under lateral confinement is relevant to primary cementing in CO2 geosequestration wellbore in saline aquifer. Geopolymer cement was cured in saline water (both at ambient conditions for 28 d...

Water susceptible properties of subgrade soils play important role in the structural design of highways. In this research study laboratory investigations were conducted on subgrade soil samples for determining the influence of water susceptible properties on Natural moisture content, Optimum moisture content, Compaction, California Bearing Ratio (CBR)-soaked and unsoaked, and Unconfined Compres...
