Salt resistance of metakaolin and asphalt waste dust-based geopolymer

Conventional Portland cement concrete is prone to durability issues in environments with salt contamination, where corrosion, expansion, and cracking are common. Dissolved salts are particularly aggressive and act as direct agents of concrete deterioration. The study focuses on synthesizing geo-polymer materials made o...

Comparative Study on the Enhancement of Soil Cement Strength Using Bentonite and Polyurethane Foam

The construction of buildings and infrastructure on soft ground, such as soft Bangkok clay, presents significant geotechnical challenges due to its high compressibility, high settlement potential, and low bearing capacity. Consequently, soil-cement stabilization is widely applied to improve the strength of soft ground....

Ground response analysis during a strong earthquake triggered by the Musi Segment of the Sumatra Fault in Kepahiang, Indonesia

Holistic assessment of building behaviour in severe earthquakes: integrating ground response with structural dynamics and ground motion assessment

This study analyses the Moot Court at the University of Bengkulu, Indonesia. The seismic ground response analysis and dynamic analysis are performed. The ground-motion parameters and the intensity of ground shaking are also discussed. The distribution of internal forces and stress ratio is presented. The identification...
