Embodiment 1

[0038] Example 1: Production of light heat-preservation and heat-insulation raw earth materials reinforced by high-strength plant fibers and cement

[0039] 1. Use a feed crusher to crush plant or crop straw into plant fibers for later use;

[0040] 2. Formulate the mix ratio of plant fiber and cement-reinforced lightweight thermal insulation raw soil material as shown in the following table:

[0041]

[0042] C represents cement, E represents raw soil, and P represents plant fiber; the ratio in the table is the weight ratio of dry materials.

[0043] 3. Prepare materials according to the weight ratio of materials;

[0044] 4. Put the fire retardant and preservative in the container and stir well until they are completely melted, and set aside;

[0045] 5. Put the raw soil, fiber and cement into the mortar mixer, pour in the dissolved fireproofing agent and preservative, add water and stir;

[0046] 6. After stirring evenly (the time is not less than 10 minutes), pour th...

Embodiment 2

[0048] Example 2: Production of low-strength plant fiber and cement-reinforced lightweight thermal insulation raw earth material

[0049] 1. Use a feed crusher to crush plant or crop straw into plant fibers for later use;

[0050] 2. Formulate the mix ratio of low-strength plant fiber and cement-reinforced lightweight thermal insulation raw soil material as shown in the following table:

[0051]

[0052] C represents cement, E represents raw soil, and P represents plant fiber; the ratio in the table is the weight ratio of dry materials.

[0053] 3. The rest of the manufacturing process is the same as in Example 1. The self-weight of blocks made by this method is about 600kg / m 3 , the thermal conductivity is about 0.1W / (m·K), and the thermal insulation ability is stronger. It can be used to build frame-filled walls of energy-saving buildings.

Embodiment 3

[0054] Example 3: Made with only plant fiber-reinforced lightweight heat-preservation and heat-insulation raw earth materials

[0055] When the raw soil where the project is located is very viscous, no cement can be added as a cementing material, and only plant fibers can be used to strengthen the raw soil. This kind of plant fiber-reinforced light-weight thermal insulation raw soil material has better environmental effects and lower cost. The production method is as follows:

[0056] 1. Use a feed crusher to crush plant or crop straw into plant fibers for later use;

[0057] 2. Formulate the common mix ratio of plant fiber-reinforced lightweight thermal insulation raw soil materials as shown in the following table:

[0058]

[0059] E represents raw soil, P represents plant fiber; the ratio in the table is the weight ratio of dry material.

[0060] 3. Before the weight of the raw soil is weighed, a simple moisture content test is required, and the weight of the raw soil ...

Abstract

The invention discloses a light thermal insulation raw soil material strengthened by plant fiber and cement. The material is produced by the following steps: natural raw soil is taken as a main material, and the plant fiber, the cement and other additives are added into the main material, are mixed by adding water into the mixture and then are naturally dried. The material has the characteristicsof light self-weight, good thermal insulation performance, simple production technology, circulating use, easy degradation, low production cost, maintenance of the texture and tactile sensation of the prior raw soil wall body and so on, is green and environment-friendly material suitable for village and town buildings and tourism buildings, can be used to substitute the prior rammed earth and adobe, can also substitute a solid clay sintered brick as a wall body material of the village and town buildings, and can also be used for paving floors and roofings to improve thermal insulation and sound absorption performances of the positions.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a light-weight thermal insulation raw earth material reinforced with plant fiber and cement. Background technique [0002] At present, under the background of rapid urbanization, as a construction industry that consumes a lot of energy and resources, it is necessary to develop green buildings and change the mode of high investment, high consumption, high pollution, and low efficiency in the construction industry. Village and town buildings account for more than 50% of the country's construction area. Under the situation that the contradiction between resources, environment and development is becoming more and more prominent, village and town buildings should do their best to reduce the pressure on resources and the environment. Therefore, vigorously develop the research and practice of green buildings in villages and towns. It is of great significance to build n...
