美国专家研究出一种用废木料生产混凝土的技术。该项技术是把废木料加工成小碎块,用以代替石子,生产重量较轻的及强度足可适应某些用途的混凝土。 用废木料生产的混凝土与标准混凝土相比,在压缩试验时前者的强度是后者的三分之一,在弯曲试验时前者的强度是后者的二分之一,在比重方面前者比后者轻四分之一。这种轻型混凝土可用于临时交通栅栏、交通路标底座、停车场的水泥填料以及铺设人行道等。
U.S. experts have developed a technique for producing concrete from waste wood. The technology is to process waste wood into small pieces instead of stones to produce concrete with lighter weight and strength suitable for certain applications. Compared to standard concrete, the concrete produced from waste wood is one-third the strength of the former in the compression test, and the strength of the former is one-half the strength of the latter in the bending test, and the former is the latter in terms of the specific gravity. One quarter lighter. This lightweight concrete can be used for temporary traffic fences, traffic signposts, cement fillers for parking lots, and paving of pavements.
