STUDY ON PREPARATION METHOD OF FIBER CERAMSITE MADE FROM WHEAT STRAW AND FLY ASH
摘要
Abstract
Fiber ceramsite was made from fly ash, wheat straw and admixtures (cement, lime, gypsum and water glass) by the processes of mix, balling, aging and maintenance. Took specific surface area (SSA) as the main investigation index, the effect of admixtures, straw particle size and its dosage on fiber ceramsite's SSA were analysed through single factor experiment and orthogonal test, and the results showed that, the primary-secondary influencing factors of admixtures on SSA could be arranged as follows: lime>water glass>cement>gypsum, the optimum preparation solution of fiber ceramsite made from wheat straw and fly ash was : selected and used 10% wheat straw grinded twice, that was to say, the mass ratio of wheat straw and fly ash was 1 : 9: the use level of admixtures was: lime 8%, water glass 2%, cement 3%, gypsum 2. 5%, and the SSA of fiber ceramsite obtained under this condition was 7. 925 m2/g.关键词
