国外水利工程用的建筑材料,几十年来,大量的仍然是传统的土、石、水泥混凝土。看来在今后若干年内.这种状况也是不会改变的。但是近三十年,由于高分子化工迅速发展,高分子产品质量不断提高,价格不断降低,从而有可能将其引用为水工建筑材料,并取得多快好省的效果。虽然使用量还不多,但品种逐渐在增加,使用范围也在扩大。加之世界各国对新材料的研究都很重视,可以予期,高分子材料的应用必将获得更大的发展。下面我们分六个方面介绍它在水利工程中的用途。
Foreign water conservancy projects with building materials, for decades, a large number of still traditional soil, stone, cement concrete. It seems that in the coming years, this situation will not change. However, in the recent three decades, due to the rapid development of polymer chemicals, the continuous improvement of the quality of polymer products and the reduction of prices, it is possible to quote them as hydraulic construction materials and achieve the result of being more efficient and economical. Although the amount used is not much, but the variety is gradually increasing, the use of the area is also expanding. In addition, all countries in the world attach great importance to the research of new materials and can expect the application of polymer materials to achieve greater development. Here we introduce its use in hydraulic engineering in six aspects.
