The most outstanding problem militating the production of earth block in Nigeria, is exorbitant prices cement, rice ash replaced with stabilized compressed to carry load. main objective this study was investigate sustainability earthen construction a partial replacement cement using Rice Husk Ash (RHA). RHA bye-product material obtained from combustion husk which consists non-crystalline silico...

Cement is a key construction material in civil and geotechnical engineering. However, its application for stabilization of marine sediments needs further investigation. This paper tests the effects varied amounts Portland cement added to soil samples on leaching tributyltin (TBT) from contaminated evaluates pH level. Identifying best combinations / slag Kiln Dust (CKD) effective treatment centr...

The study aims to develop a reliable model using gene-expression programming (GEP) technique for estimating the unconfined compressive strength (UCS) of soil stabilization by cement and fly ash. considered effects several parameters, including ash characteristics such as calcium oxide (CaO) content, CaO/SiO2 ratio, loss ignition. research results show that proposed demonstrates superior perform...

Drilling boreholes in gas zones and with the possibility of migration or exhalation requires a high index well tightness. An important parameter determining effectiveness sealing annular space is adhesion cement sheath to rock formation. Low values formation casing surface result uncontrolled flows. The lack also reduces stabilization pipe column. To obtain required adhesion, should be properly...
