Abstract

The invention relates to the technical field of rammed earth materials, and discloses a rammed earth material for a light rammed earth wall, which is prepared from the following components in parts by weight: 0.39 to 0.49 part of clay, 0.08 to 0.18 part of granite, 0.13 to 0.23 part of sand, 0.14 to 0.24 part of lime slurry and 0.04 to 0.08 part of sawdust powder. The preparation method of the rammed earth material comprises the following steps: mixing the clay, the granite, the sand, the lime slurry and the sawdust powder according to the proportion, and uniformly stirring to obtain the rammed earth material. The invention further discloses application of the rammed earth material in manufacturing of the light rammed earth wall, and a manufacturing method of the light rammed earth wall sequentially comprises the steps of formwork erecting, pouring, formwork removing, maintaining and plastering. The rammed earth material is suitable for light rammed earth walls and has good cohesiveness, heat preservation and insulation performance, sound insulation and noise prevention performance and pressure resistance.

Description

technical field [0001] The invention relates to, in particular, a rammed earth material for a lightweight rammed earth wall, a preparation method and application thereof. Background technique [0002] Rammed earth construction is a building in which undisturbed raw soil is rammed layer by layer with tools such as stone or wooden hammers to build load-bearing walls. As a traditional building, rammed earth building is still favored in some rural areas of my country because of its low cost, energy saving and environmental protection, good thermal insulation performance, convenient construction, local materials, reusable wall materials and comfortable living. widely used. [0003] For rammed earth walls, its mechanical properties are affected by factors such as the chemical composition and physical properties of the soil itself. However, due to the low material strength of the soil itself of the traditional rammed earth wall, and it is a brittle material under dry conditions, t...
