Numerous soil water repellency (SWR) studies have investigated the possible causes of this temporal phenomenon, yet there remains a lack knowledge on order importance main driving forces SWR in context changing environmental conditions under grassland ecosystems. To study separate and combined effects texture, climate, cover type inducing or altering SWR, four sites from different climatic regi...

Ultra-High Strength Fibre Reinforced Self Compacting Concrete (UHSFRSCC) is in great demand for use construction projects around the globe. Unless fillers are utilized this concrete, its production will come at an excessive environmental cost due to high Carbon footprint of Portland cement. A gap published literature was identified, where quaternary mixes, containing cement with three fillers, ...

This research was carried out to evaluate the relationship between incorporation of calcite precipitation bacteria, sporosarcina pasteurii using calcium lactate as nutrient source and properties calcined clay limestone powder blended self-compacting concrete. Ten mixes were designed designated S0 S9 with control (without bacteria nutrient) S1 at varying concentrations effect cell density concen...

Silica fume (SF) and Metakaolin are cementitious materials used as admixtures to produce high strength concrete and to reduce the permeability. Also, Silica fume is used to make durable concrete structures in combination with ordinary Portland cement. In places where insufficient or poor curing concrete structures like sea shores, underground structures which undergo severe loss of compressive ...

Spherical polymeric microcapsules, carrying liquid sodium silicate, were used for autonomic self-healing of mortars. Microcapsules were added at varying volume fractions (Vf), with respect to the cement volume, from as low as 4% up to 32% and their effect on fresh, mechanical and self-healing properties was investigated. For this purpose a series of techniques were used ranging from static mech...
