Experimental Study On The Performance Of Permeable Concrete

With the progress of science and technology,people are enjoying the convenience of the fast speed development of the society.At the same time,they also began to suffer the serious consequences from the deterioration of the environment.Fragile underground pipe network system,rugged hardened pavement,"sea-vie wing" created by rain is one of the consequences.Such man-made disasters seriously trouble people's life and work,and even make reduce the safety of life and property.Environmental protection and sustainable development can not be ignored.The General Office of the State Council promulgated the guide on promoting the Sponge City,marks the conception of China's urban development and its construction method.The construction of Sponge City should base on the following points:1.Change the traditional way of filling lake and gully,so as to reserve the rivers,lakes,wet lands to maximum.2.Use the combination of physical,biological and zoological methods to repair the damaged Sponges.3.Create a certain size of new Sponges when constructing cities,such as greening the roofs,permeable pavements and squares.This paper focuses on the requirements of the construction of permeable pavements and squares.Specific research plans are as follow:1.Select proper raw material,determine the method of the design of mix proportion(this paper selects volume method to calculate the test mix,and through the test data to prove that the chosen test method is feasible or not.)2Use different water cement ratio,aggregate size and sand ratio to test,and compare and analyze each group of experiment data.3.Analyze test data,summarize the factors that influence permeability and strength,determine the mutual relations concerned.4.An engineering example was given to testify the effectiveness and feasibility of the research conclusion.5.According to the results of this research,analyzing the performance and application of the permeable concrete.
