My comment:
(a) The first two thirds of this article talks about things we already know. Please read from paragraph 3 of web page 2 that starts with "Word went forth."
(b) The report cites
Stephen Chen, 'Judgment Day' Fears for High-Speed Rail Tracks. South China Morning Post, Jan 10, 2011
http://topics.scmp.com/news/china-news-watch/article/Judgment-day-fears-for-high-speed-rail-tracks
("mainland could produce enough high-quality fly ash for the construction of 100 kilometres of high-speed railway tracks a year. But more than 1,500 kilometres of track have been laid annually for the past five years")
Note:
(i) fly ash 粉煤灰/飛灰
http://en.wikipedia.org/wiki/Fly_ash
(fine particles that rise with the flue gases. Ash which does not rise is termed bottom ash; often used to supplement Portland cement in concrete production)
* Portland cement
http://en.wikipedia.org/wiki/Portland_cement
(the most common type of cement in general use around the world; developed from natural cements made in Britain, and its name is derived from its similarity to Portland stone, a type of building stone that was quarried on the Isle of Portland in Dorset, England; patented in 1824)
(ii) First Survey and Design Institute of China Railways

(iii) WANG Lan/Cement and New Building Materials Research Institute under the China Building Materials Academy

(iv) The report said concrete blended with high-quality fly ash "can give the tracks' concrete base a lifespan of 100 years," whereas that blended with poor-quality fly ash "would mean China's high-speed rail tracks would last only 50 years."
