Breathing dust that contains respirable crystalline silica can lead to silicosis, a deadly lung disease. Respirable dust is that fraction of the aerosol that is small enough to reach the deeper, gas-exchange regions of the lungs. No effective treatment exists for silicosis, but it can be prevented by controlling workers’ exposures to dust containing crystalline silica. Exposure to crystalline s...

This paper investigates the possibility of recycled aggregate use in concrete slabs with hollow cores. The main variables considered experimental study for were percentage and core number. Six dimensions (1000 × 500 120) mm was fabricated tested. results showed that addition affected ultimate strength, ductility, energy absorption members. An increase to 25 % decreased strength capacity by 3.54...
