Development Level

Sustainable development is a hot issue under the current background of resources and environmental crises. In this paper, Liaocheng City's sustainable development level is evaluated by using fuzzy comprehensive evaluation method. It is concluded that Liaocheng City's sustainable development level turned out to be moderate. The constraints of Liaocheng City's sustainable development are sustainable development awareness isn't formed and some problems are serious. Trains of thought include: strengthen sustainable development concept's understanding, strengthen capacity-building of improving sustainable development level and solve sustainable development practices' current problems.

Self-compacting concrete (SCC) has been widely used in engineering for improving the product quality and efficiency at the construction sites, enhancing the working conditions and the appearance of concrete. Workability is an important property of SCC. But none of a single method has been developed for evaluation workability of SCC efficiently. Aiming at the quality control of fresh SCC, a fuzzy comprehensive evaluation method for evaluating workability of SCC was put forward and a case study was done by measuring slump, slump flow, L-box ratio, J-ring flow, bleeding and sieve segregation of fresh SCC in the present paper. Evaluation results indicated that fuzzy comprehensive evaluation method can give a quantitative evaluation of workability of SCC and it is convenient to establish an expert system for controlling the quality of fresh SCC by using fuzzy comprehensive evaluation method.
