Previously, coal ashes have been used to prepare advanced materials such as glass-ceramics with the hardness of 6.35 GPa, geopolymer concrete with compressive strength of over 30 MPa and zeolite A with a Cr (III) removal capacity of 35.8 mg/g.
Moreover, the use of fly ash for building materials and other advanced materials will allow for sustainable utilization of this resource.

The Dilemma of the Implementation of the Yangtze River Delta Regional Planning YONG WANG1,2, a, LIANG JIANG2,b 1College of Architecture and Urban planning, Suzhou University of Science and Technology, Suzhou 215011, Jiangsu, China 2 Faculty of Advanced Technology, University of Glamorgan, Pontypridd, CF37 1DL, UK awyong006@gmail.com, bljiang@glam.ac.uk Keywords: Regional cooperation; Regional coordination; Conflicts of interests; Dilemma of cooperation; The Yangtze River Delta regional planning.
The State Council formally approved the implementation of the "Yangtze River Delta regional planning"（YRDRP）on May 24, 2010 and established its strategic position of the YRD to becoming an important international gateway to the Asia-Pacific region, providing the world class services and advanced manufacturing center, with strong international competitiveness of world-class city group [4].
They can cooperate to advance regional mutual interests in the social and economic development.
Some of the projects have created world class achievement in engineering.
The Yangtze River Delta Forum, which is held twice a year, would be unlikely to take up the responsibility to eliminate the conflict of interest among the provincial and municipal administrative divisions.
