一种理论新近提出:建造埃及金字塔的石头完全是人工制造的,是一种类似混凝土的块料。这样,建造金字塔就不象过去我们想象的需要的那么多人了。在一些老的电影剧本里写到:数万名奴隶从采石场艰难地凿下几百万块石灰石厚板,每块重达三至六吨,再沿斜坡拖到工地。美国佛罗里达州迈阿密巴里大学的化学家约瑟夫声称,那些石块是用压碎的石灰石泥浆同矿物粘合剂混合,然后注 One theory recently proposed that the stone from which the pyramids of Egypt were constructed is completely artificial and is a concrete-like block. In this way, building the pyramid is not as many people as we had imagined in the past. In some old screenplays, tens of thousands of slaves struggled to chisel millions of limestone slabs from the quarry, each weighing three to six tons and dragging it along the slope to the site. Joseph, a chemist at Barry University in Miami, Florida, claimed that the stones were mixed with mineral binders with crushed limestone mud and then
