As a result of the analysis of space images, it was found that the area of the Kakhovka reservoir decreased...

The purpose of this paper is volumetric quantification of soil erosion using the so-called erosion bridge. For the measurement, a locality in the South Moravian Region of the Czech Republic was chosen. With the erosion bridge, we can measure erosion rills. Rill erosion is caused by concentrated water flow. It occurs when runoff water forms small channels as it concentrates down a slope. The erosion bridge is a very simple device that enables us to accurately measure the shape of the soil surface in a given place. ...

Green building materials are gaining attention for achieving carbon neutrality in civil engineering. To reduce CO2 emissions from cement, using low-cement or cement-free materials with local supplementary cementitious materials (SCMs) is promising. Blended cements with SCMs enhance long-term strength, but low-clinker blends often have low early strength. To address this, understanding the hydration of ordinary Portland cement is crucial. While C3S has been studied, the role of C3A, the most reactive component of c...
