Nano-material reinforcing agent and application method thereof in reinforcement of earth construction

Abstract

The invention provides a nano-material reinforcing agent. The nano-material reinforcing agent comprises 1 to 2 parts of polyacrylamide, 30 to 40 parts of calcium hydroxide, 5 to 20 parts of slag, 1 to 30 parts of nanometer silicon reinforcing liquid, 5 to 20 parts of micro silicon powder, 1 to 3 parts of calcium sulphoaluminate, 5 to 10 parts of bentonite, and 5 to 10 parts of expanding agent; the content of free water in solid raw materials is not greater than 3%; the solid-state raw materials are uniformly milled through a ball mill, and the specific surface area of the solid-state raw materials is 280 to 320m<2> / kg. The invention discloses an application method, comprising the following steps of: uniformly stirring the reinforcing agent in which the solid powder accounts for 20 to 60% of mass of clay; adding a nano-siliceous reinforcing agent that accounts for 20 to 25% of total mass of a solid-state material and mixing uniformly; and then covering a plastic film and standing for 60 to 120 minutes. After the original earth construction is reinforced in a paving way and an inlaying way, the shortcomings that the raw earth material is poor in resistance to bending, shearing, folding, water stability and the like are overcome; the reinforced wall body has the appearance same as that of the original wall body, the adhering effect and the water resistant performance are obviously improved, and the resistance to freezing and thawing and the resistance to sulfate corrosion are improved, therefore, the positive and effective effect is provided for stably reinforcing the earth construction.

Description

technical field [0001] The invention relates to the technical field of construction engineering and the technical field of cultural relics protection engineering, in particular to a nanomaterial reinforcing agent and a method for reinforcing raw soil buildings. Background technique [0002] Raw soil architecture refers to buildings that use unroasted but simply processed undisturbed soil as the material to build the main structure. Typical adobe buildings such as the ruins of the ancient Great Wall, ancient tombs and relict sites of the old city. Adobe architecture has a long history and is widely distributed, and it is one of the most representative features of human beings from primitive to civilization. It is of great significance to the protection of raw earth buildings. [0003] Raw earth architecture originated in the central and western regions of China, which is dry and rainless, and the rich loess layer became a natural building material in the early Chinese civil...
