00:00would you dare live under a roof like this no rebar skeleton no monolithic concrete pour
00:05workers first erect steel beams then insert red bricks one by one between the beams
00:09most people's first reaction this can actually be a roof in many places this method is very common
00:14construction speed is fast entire roof surface formed in under half an hour
00:18then comes the critical part cement mortar fills every brick joint one by one once mortar cures
00:23steel beams bricks and mortar lock together sharing the load as one unified system that's
00:28what keeps it stable structure is simple but genuinely practical more realistically red bricks
00:33are low cost process is straightforward ordinary workers can build it but when conditions improve
00:38the approach changes completely workers first lay tiles face down as bottom formwork then arrange
00:43rebar building up the skeleton finally pour concrete across the entire surface in one core forming one
00:48complete unified structure this method is stronger and more stable but also slower more expensive and
00:53requires skilled workers simply put two choices combined construction saves money and labor does the job
01:00monolithic pour better performance higher cost
