This study reports the influence of different climatic ambient temperatures on thermal properties fiber-reinforced lightweight aggregate concrete (LWAC). Lightweight expanded clay aggregates (LECA) with steel (ST) and polypropylene fibers were used in mix proportions. The steady-state test was performed samples at oven-dry state measurement taken six 0 °C, 10 20 30 40 50 °C. results show a line...

This study examines the impact of bacterial concrete on strength and self-healing. Bacterial has better compressive strength, permeability, corrosion resistance, chemical precursors, alkalinity mechanical stress. Bacillus subtilis calcium lactate spore powder effects are explored in this study, influence form self-healing capacity to crack repair. The concentration 105 cells/mL is used with 0.3...

The present study aimed to determine the kinetics of pollutant removal in biofilters with LECA filling (used as a buffer prevent de-icing agents from being released into environment stormwater runoff). It demonstrated significant effect temperature and C/N ratio on rate nitrification, denitrification, organic compound removal. nitrification was highest (0.32 mg N/L·h) at 25 °C = 0.5, whereas lo...
