2022年12月1日 · EICP treatment has improved the erodibility behavior of the beach sand. Strong positive correlations were observed between CaCO 3 precipitation and soil properties improvements.

2019年1月4日 · The EFA is a laboratory device used to measure the erosion function of a soil defined as the relationship between the soil erosion rate and the water velocity or the water shear stress. In this study, three different types of enzymes were used to treat two different types of soils: a low-plasticity silt and a silty sand.

Sandy efa belongs to the order of scaly snakes (family of vipers). The optimal living conditions for this reptile are rather arid climate, as evidenced by the area of its distribution (African deserts and wastelands, southern regions of Asia).

Using erosion function apparatus (EFA) in combination with an ultrasonic P-wave reflection monitoring device, the effect of exocultured biopolymers on the erosion parameters of critical shear stress and the erodibility coefficient was examined in …

2019年3月1日 · Crude urease-induced mineralization is a promising biological ground improvement technology with the advantages of low-cost and sustainability. Enzyme-induced carbonate precipitation (EICP) based on… The addition of enzymes is seldom used to improve the resistance of geotechnical structures against erosion by rain and wind action.

2019年3月1日 · The EFA is a laboratory device used to measure the erosion function of a soil defined as the relationship between the soil erosion rate and the water velocity or the water shear stress. In this...
