Plant fiber reinforced alkali slag cementing material and preparation method thereof

Abstract

The invention relates to a plant fiber reinforced alkali slag cementing material and a preparation method thereof. To solve the problem of large brittleness of alkali slag cementing material, an adobe wall preparation method for doping certain wheat-straws, rice straws and other plant fibers into adobe of an adobe wall to improve ductility is referred, and plant fibers are added into an alkali slag cementing material in a test to improve the defect of large brittleness. The preparation method comprises the following steps: carrying out alkali treatment on plant fibers, namely soaking the plant fibers with a sodium hydroxide solution having the mass percentage of 10 percent for 20 minutes or 60 minutes; rinsing with clear water, naturally drying the alkali-treated plant fibers in a shadow place until the moisture content is 15 percent for use, and doping the plant fibers into the alkali slag cementing material. The invention is applicable to plant fiber reinforced alkali slag cementing materials and the preparation method thereof.

[0004] Background technique: [0005] In order to solve the problem of high brittleness of the alkali slag cementitious material, referring to the practice of adobe wall, some plant fibers such as wheat straw and rice straw were mixed into the adobe body to improve its ductility. fiber to improve its brittle shortcomings. Moreover, most of the plant fibers are agricultural wastes, and most of them are abandoned or burned, which not only takes up space but also pollutes the environment. If recycled, it can not only improve the ductility of the alkali slag cementitious material, but also make the resource recycling, and can also reduce straw burning.

[0005] In order to solve the problem of high brittleness of the alkali slag cementitious material, referring to the practice of adobe wall, some plant fibers such as wheat straw and rice straw were mixed into the adobe body to improve its ductility. fibers to improve its brittleness

Moreover, most of the plant fibers are agricultural wastes, and most of them are abandoned or burned, which not only takes up space but also pollutes the environment. If recycled, it can not only improve the ductility of the alkali slag cementitious material, but also make the resource recycling, and can also reduce straw burning. Pollution of the environment can be said to kill three birds with one stone. Therefore, it is of great theoretical and practical significance to study the mechanical properties of plant fiber reinforced alkali slag cementitious materials at room temperature and after high temperature.
