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...

In underground engineering, cement-soil reinforcement beneath a peat soil environment is significant challenge. To investigate the corrosiveness of fulvic acid on and its micro fine structure changes under (PSE), an experiment was conducted to prepare by mixing humic (HA) into alluvial clayey then adding cement make specimen, which soaked in (FA) solution deionized water simulate different work...

The goal of this study was improvement of sandy soil using a combination of polystyrene foam container waste and Portland cement. For this purpose, Babolsar sand was used as the base soil. Strips of disposable polystyrene foam container waste in “chips” of 50 ´ 5 mm and 50 ´ 10 mm were added to the soil at 0.0%, 0.1%, 0.2% and 0.3% by weight along with 3% Portland cement at a relative density o...

Taking loess as the research object, influence of cement content on mechanical properties was studied. Firstly, basic physical parameters were obtained through laboratory index test, and improved by using Portland cement. Secondly, under different incorporation ratios (3%, 5%, 7%, 9%), heavy compaction test liquid-plastic limit carried out respectively to obtain cement-improved loess. Finally, ...

Cement stabilized soil is one of the commonly used as ground reinforcement solutions in geotechnical engineering. In this study, main object was to apply three machine learning (ML) methods namely gradient boosting (GB), artificial neural network (ANN) and support vector (SVM) predict unconfined compressive strength (UCS) cement soil. Soil samples were collected at Hai Duong city, Vietnam. A to...

20 soil samples collected from the vicinity of the Khash Cement plant, Iran, were analyzed for As, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb and Zn using ICP-OES. The results revealed that the metal distribution were in a fluctuating manner considering various distances and direction from the cement facility. However, it was observed that the mean concentration of the soil samples has no special trend wit...
