我国是一个盛产竹材的国家。据估計每年产量大約为四十万吨,其中以毛竹产量最多。竹材天然就是一种很好的建筑材料,它的拉力强度大,价格低廉,而且生長很快,生長了三四年以后就可以利用,因此利用竹材代替鋼材和木材,对于国民經济有很大的意义。如果將鋼筋混凝土中的鋼筋用竹筋代替,將为国家节約大量的鋼材。几年來,国內各科学研究机構、高等学校和企業部門都进行对竹筋混 China is a country rich in bamboo. It is estimated that the annual output is about 400,000 tons, of which the most is the production of bamboo. Natural bamboo is a very good building material. Its tensile strength is strong, its price is low, and it grows very fast. It can be used after it has been growing for three or four years. Therefore, the use of bamboo instead of steel and wood has great impact on the national economy. significance.
