Rammed earth wall material with high strength, good corrosion resistance and abundant colors and textures

Abstract

The invention belongs to the technical field of building materials, and concretely discloses a formula of a rammed earth wall material with various color combination and texture effects. The rammed earth wall material is characterized in that the rammed earth wall material comprises a base material and a visual effect adjusting material; the base material comprises, by volume, 35-48% of yellow mud, 12-26% of sands, 20-26% of fine cobblestones, 10-13% of rough cobblestones, and a proper amount of water, wherein the particle size of the fine cobblestones is smaller than 10 mm, the particle size of the rough cobblestones is 10-20 mm, and the content of water makes the rammed earth wall material not become loose after being held in hands; and the visual effect adjusting material is colored cement, and the volume percentage content of the colored cement is 2-16%. The rammed earth wall material has the substantial advantages of abundant colors and textures, good corrosion resistance, high strength, low production cost, and greenness and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a rammed earth wall material which can improve the color and texture effect of a rammed earth wall, increase the strength and corrosion resistance of the rammed earth wall, and a rammed earth wall made of the same. Background technique [0002] Rammed earth building, also known as raw earth building, refers to a building form that uses soil as the main building material and is compacted by ramming technology. According to literature records, rammed earth architecture first appeared in my country in the new era more than 4,000 years ago. In the long history, rammed earth buildings have been widely used in a large number of military and civil buildings due to their significant advantages such as closeness to nature, simple craftsmanship, energy saving, low cost, warm in winter and cool in summer. The most outstanding representative of rammed earth constructi...

Problems solved by technology

[0003] Aiming at the technical problems of monotonous color, single texture effect, insufficient strength and poor corrosion resistance of traditional rammed earth building walls, the present invention provides a rammed earth wall material formula with high strength, corrosion resistance, and rich colors and textures. By changing the ratio of rammed earth materials and introducing colored cement components and stone components with different particle sizes, the earth wall material formula not only has the advantages of traditional rammed earth materials such as green ecology, energy saving and environmental protection, flame retardant and wear-resistant, and good heat insulation performance. Advantages, it also improves the strength and corrosion resistance of the rammed earth wall, endows the rammed earth wall with a variety of color choices and texture effects, enriches the expressive ability of rammed earth buildings, increases the applicability of rammed earth walls, and fills the market blank
