Sulfur oxygen magnesia cement materials and wood chips , bamboo , making instead the concrete supporting mold with wood Fangmu material , of this Fangmu material has difficult to burn , not easily deformed , not back to halogen , sawing can be nailed , quality lighter, fire performance , environmental protection and other advantages , in particular, requires no rust on metal . Experimental study on the ratio of the the the sulfur oxygen needed by the the production Fangmu material magnesium gelling material under normal temperature conditions . In order to improve the performance indicators of the cementitious material , respectively on the basis of the reference ratio incorporating a variety of different additives , screened out of the strength is significantly increased admixture of citric acid , sodium citrate , sucrose, through optimization of the admixture of test to determine the ratio of the of thioredoxin magnesium cementitious materials . To further reduce the production cost of the cementitious material . Imitating wood materials water resistance of the inorganic filler ( fly ash and slag ) experiment , comprehensive assessment , the effect of fly ash . Produced a template Fangmu specimen the static bending order to increase Fangmu template strength , making Fangmu , template specimen when the template on the lower surface of each mosaic layer of bamboo or a glass fiber mesh , by detecting the test piece the physical performance , come join bamboo specimen bending strength is relatively high , seven days maximum static bending strength is 16.6MPa, reaching 55% of the value of the project design strength , also of Fangmu template density , water absorption , nail holding power , and other performance testing, performance basically meet the specification requirements for concrete formwork . Actual experimental results can be inferred , wood material and will certainly become a sustainable development of a new type of environmentally friendly construction materials .
