The materials are mixed in the using place , but it should be not concreted before mixture by 24 hours , and after 24 hours it results in quick-concreting .
The main materials consist of sulphur aluminate cement , retarder and suspend agent .
The prepared materials consist mainly of gypsum , lime , suspend agent , quick-hardening early strength agent and so on .
After the main materials and the prepared materials are mixed by water separately , hydration reaction would create a great amount of ettringite (3CaO·Al2O3·3CaSO4·32H2O) in crystal cell of ettringite , the cubage of water molecule is greater than 80% , thereby , the high water cement ratio is realized [1~5] .

Materials and Methods Materials.Banana peel: Banana is planted in Guangdong, China.
Results and discussion The effect of the different ration of materials on squeezing.As shown in Table 2, density of extrudates increased with banana peel powder addition.There is solid evidence in the literature that as high-fibre materials are added, density is expected to increase [13].
