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 ...
