| Title of the article | Structure and properties of gypsum cement-pozzolan matrix reinforced with cellulosic fibers |
| Abstract. | Problem statement. Different types of sheet materials and products are used for outside and interior finish of the industrial and civil buildings and structures. The products based on gypsum binder that has unique domestic mineral raw material base, appreciable quantity of discovered resources and low fabricating cost are of special interest among these sheet products. Besides, at the present time the reduction of using these products is observed. In connection with this there is considerable interest in quality improvement and quantity increase of consumable products based on gypsum and mixed gypsum binders. The research objective is studying the influence of the rate of cellulosic fiber opening and content of cellulosic fibers on the structure and properties of gypsum-cement-puzzolan matrix. Results. The function of the type of reinforcing fibers in structure formation and properties of gypsum-cement-puzzolan compositions is studied in the article. Positive influence of cellulosic fibers on the properties of investigated modified matrixis observed. It is found that the best ultimate strength indexes while using cellulosic fibers can be achieved with its mixing ratio in amounts of 0,5-1 % by weight of binder and freeness rate of 30°SR. Conclusions. Signification of obtained results for construction industry consists in possibility of productionthe sheet materialsbased on gypsum binder with advanced physical and mechanical properties by means of fiber reinforcementof gypsum-cement-puzzolan matrix by cellulosic fibers. |
