澳大利亚科学家研制出一种用淤泥和煤烟灰制作的砖头。这种砖的重量比泥土砖轻20％,但保留了普通建筑用砖的其他特性。科学家们把这种砖命名为“生物煤灰”(BIOFLY)砖。这是他们用了5年时间研制出来的独家产品,现在准备批量生产。伍伦贡大学工程学副教授西瓦·西瓦库马尔说;“我们的方法采用了两种废料,在别的地方还没有见过这种结合”。新型砖名字中的“FLY”不是指烧砖使用的淤泥招来的小虫子,而是指火力发电站产生的废弃物“煤烟灰”
Australian scientists have developed a brick made from silt and soot. This brick is 20% lighter than mud bricks, but retains the other characteristics of ordinary building bricks. Scientists named this brick “BIOFLY” brick. This is an exclusive product that they developed over five years and is now ready for mass production. Syva Siwakumar, an associate professor of engineering at Wollongong University, said: “Our approach uses two types of waste that have not been seen elsewhere.” The “FLY” in the new brick name does not refer to the small insects that the sludge used in burning bricks attracts, but refers to the waste “coal soot” generated by thermal power stations.
