Polymers not only possess repairing functions concerning the concrete structures, but also due to their properties are used in making different types of polymer cements and improving the matrix structure of cement materials, enhancing the viscosity, mechanical, and stability power of concretes. Today, there is limited knowledge on the use of SBR in structural light aggregate concrete. In the pr...

The aggregate skeleton significantly influences the deformation resistance of asphalt mixtures. A stable has good interlocking effects and load transfer ability to resist mixtures during loading. Therefore, methodology accurately evaluate morphology based on mechanism inside is great value predict mixture stability. objective this study validate stability from perspective evolutional morphologi...

In the mesic savannas of West Africa, areas around villages relatively tall and dense forest vegetation are often found. These ‘forest islands’ presumably direct outcome human activity. To better understand these patches with luxuriant vegetation, our study focused on how they influence soil aggregate stability- a key indicator resilience to degradation through erosion. We compared proportion s...
