Research of Meso-pore Structures of Eco-material
A proposed method was introduced to study the meso-pore structures of eco-material in this paper. Firstly, the samples were solidified by using the mixtures of epoxy resin, triethanolamine and blue organic dyestuff. Then, the sections were obtained by cutting the solidified samples and the digital images were gathered by using high resolution camera. At last, the IPP technique was used to analyze the digital images for studying the meso-pore structures. Experimental results show that pore number of eco-material increases with the decrease of pore-size, and the number of pores of pore-size smaller than 0.24 mm is about 30 % of total. Further more, smoother pore number distribution curve indicates more stable structure. With the increase of wet-dry cycles, the total porosity of eco-material of 3 ~ 9 cm depth tends to decrease, while that of 12 ~ 18 cm depth shows a tendency to increase.
