Design and development of SFRC and GFRP reinforced block to analyze explosion resistance strength for fireworks industries

To prevent the shattering of the wall during an explosion in the fireworks industry and to prevent the spread to adjacent rooms by Domino’s effect, it is planned to build a wall made up of mould block with fiber reinforcement. This work studied the load-carrying capacity of the reinforced block (Steel and glass fiber) by varying the reinforced percentage (1%, 1.5%, 2%, & 1% chopped/unchopped) with mould block. Various tests were conducted to validate the reinforced mould blocks’ performance. The compression strength was increased from 10.18 N/mm2 to 40.88 N/mm2 and impact resistance was improved from 19.86 J to 26.99 J for 2% reinforced blocks. The aerial impact test results show that reinforced mold blocks withstand up to 6.85 N, while the unreinforced cannot withstand even 1.53 N. The mortar bonding strength results show that the unreinforced mould block fails at the load of 37.5 kN but the 1.5% GFRP reinforced mould block fails at 72.25 KN. The real explosion test result shows that 376 psi pressure couldn’t break the GFRP-reinforced mould block whereas 197.49 psi pressure is enough to destroy the unreinforced block. The simulation analysis results show that the deformation reduced up to 41.78% for the 2% reinforced blocks. From this research, it is inferred that the fireworks building damage from disasters can be prevented using GFRP reinforced mould block.
