Liquefaction is a disaster that can damage building infrastructure. This all too common in granular sandy soils. due to the subsidence and instability of soil when subjected shocks such as earthquakes. For this reason, mitigation efforts are needed reduce risk liquefaction. study will compare effectiveness influence micro-pile, stone column, densification methods on soils at Central Java PLTU s...

The application of urea fertilizer has always been associated with heavy N losses therefore, improving its efficiency is critical to minimize economic and environmental losses associated with its application. One possible approach to improve the nitrogen losses from the surface applied urea is to coat it with sulfur, urease inhibitor (agrotain) and other biodegradable materials. A pot experimen...

A mixed bacterial culture consisted of Staphylococcus sp., Bacillus circulans-I and -II has been enriched from contaminated soil collected from the vicinity of an endosulfan processing industry. The degradation of endosulfan by mixed bacterial culture was studied in aerobic and facultative anaerobic conditions via batch experiments with an initial endosulfan concentration of 50mg/L. After 3 wee...

The bearing capacity of screw cast in situ displacement piles is mostly unexplored. There also insufficient research on silty soils. Therefore, five cone penetration tests (CPT) and one piezocone test (CPTu) using direct methods were utilised to determine the load-bearing four Estonia. In addition CPT sounding data, static-dynamic (SDT) results used analyse load-beating piles. Both deterministi...

Researchers have recently realized thatsilty laminas are very developed in naturally fractured continentalsedimentary formations in the Ordos Basin(China). Studies have shown that silty laminas are significant to improve the physical properties and gas storage capacity, and the natural fractures interact with the hydraulic fractures to maximize the fracture network during hydraulic fracturing. ...

This study aims to highlight the latest developments in field of peat soil stabilisation technology via chemical stabilisation. The review examines use traditional stabilisers such as OPC and various non-traditional stabiliser materials, i.e., Palm Oil Fuel Ash (POFA)-OPC blends, solutions, geopolymer enhance Unconfined Compressive Strength (UCS) characteristics soils based on ASTM D 4609 requi...

The article considers the possibility of using wastepaper sludge ash (WSA) as a soil reinforcement material for construction layers road wear. Loamy sand, sandy loam, silty clay were chosen soils strengthening. maximum density skeleton at optimum humidity was established by method Proctor. Wastepaper and Portland cement grade 400 used separately Six compositions strengthened each type investiga...
