On site cement mixing for Solar Bodega
Today they were going to pour cement headers at the top of the solar bodega over the windows and door. You've to to have some sort of support above those openings to carry the weight of the additional block and ultimately the roof itself. In the USA, we'd use big timbers turned sideways, or in some cash stell I beams. But here they put the steel rebar in place and then fill it with cement. And rather than getting from a truck, they just mix it, put it in buckets, and haul it one bucket at a time. I'd estimate the buckets, half full, weigh about 30 kg a piece or about 75 pounds. Watch this guy load him, carry them, and lift them. He's a working machine. Video Here of on-site cement mixing and pouring
