This paper investigates the behaviour of hybrid fibre, i.e. a combination E glass and basalt added in reinforced concrete column. A total 6 columns were cast with Conventional Concrete (CC) Hybrid Fibre Reinforced (HFRC) to study structural performance The was made cement, manufacturing sand (m-sand), coarse aggregate as major ingredients. In column, 2% Basalt fibre along E-Glass 1% make HFRC. ...

This work identifies the main phenomena that control the peptisation and transport of clay particles in a sand core. Clay can be dispersed into small particles in an aqueous solution of low ionic strength. This property is used to generate clay particles with NaCl concentration varying from 0.5 M to 0.015 M. For this purpose, a chromatographic column is initially packed with a 5 % clay-sand mix...

A simple column filtration was developed to clarify meat homogenate suitable enough to quantify and assess the viability of bacterial population using flow cytometry. The removal of debris from homogenized meat suspensions was achieved by passing through different column materials such as sand particles, glass beads, dowex resin, and cell debris remover (CDR). Total plate counts on tryptic soy ...

Soil moisture is among the key environmental variables controlling evaporation, infiltration and runoff. However, the temporal evolution of soil moisture is not easy to measure or monitor at large scales due to its spatial variability, which is largely driven by local variation in soil properties and vegetation cover. Consequently, soil moisture estimates using land surface models are typically...

Langmuir, Removal Efficiency. Abstract—Heavy metals are hazardous elements in aqueous solutions which threaten the living thing organisms. Steel making plant is among the industries which may generate high amounts of pollutants and can possess high values of heavy metals. In this research granular activated carbon material is used in two different types: 1) column made of separate layers of act...

Reactive barriers are used for in situ treatment of contaminated ground water. Waste green sand, a by-product of gray-iron foundries that contains iron particles and organic carbon, was evaluated in this study as a low-cost reactive material for treating ground water contaminated with the herbicides alachlor [2-chloro-2',6'-diethyl-N-(methoxymethyl)acetanilide] and metolachlor [2-chloro-6'-ethy...

[1] The unsteady state drainage of water from a vertical sand column with and without a finer layer on the top was studied theoretically and experimentally to investigate the airflow generated by the finer layer. The sand column, saturated at its lower portion and initially in the condition of hydrostatic equilibrium, is drained at its bottom at constant head. The results show that significant ...

Knowledge of the fate and transport of functionalized carbon nanotubes (CNTs) in porous media is crucial to understand their environmental impacts. In this study, laboratory column and modeling experiments were conducted to mechanistically compare the retention and transport of two types of functionalized CNTs (i.e., single-walled nanotubes and multi-walled nanotubes) in acid-cleaned, baked, an...
