When coal is burned in a boiler, two kinds of ash by-products are produced: a heavy bottom ash and a fine-as-powder fly ash. About 10 to 15 percent of the coal by-product is bottom ash which is used like sand on streets and highways covered with ice, and also on highways as paving material.

It is the fly ash, however, that is receiving much attention. Once considered a waste, fly ash is now regarded as a natural resource in the United States. It can be placed in some lower places, where it is compacted(压实) and covered with soil, for the seeds of various grasses and plants to be placed in the soil to make the land productive.

Fly ash may be added to concrete (混凝土)to build roads and other kinds of buildings, taking the place of the cement(水泥) up to 20 percent. As a by-product of burned coal, fly ash requires no extra energy to be produced, while cement production requires great amounts of energy.

Besides, the technology is able to take out some useful minerals from the fly ash, which is still a very expensive process today. But the time may come when it is cheaper to take out these products from ash than to mine new supplies.

A. in order to rebuild them          B. in order to make them colorful

C. so that people can walk on them   D. so that cars can run faster
