Novel color rammed earth wall and preparation method thereof

Abstract

The invention relates to the technical field of building materials, and provides a novel color rammed earth wall. According to the technical scheme, the novel color rammed earth wall includes a main body material and bamboo ribs arranged at intervals, and further includes refractory cement, toner, soil curing agent, slaked lime, main body The material includes soil, coarse sand, stone, a soil stabilizer and slaked lime. The main body material includes clay, coarse sand and gravel, and the weight ratio of the clay to the coarse sand to the gravel is 6:2:2. The refractory cement accounts for 6%-8% of the weight of the main body material, the soil stabilizer accounts for 0.02-0.04% of the weight of the main body material, the slaked lime accounts for 2%-4% of the weight of the main body material, and the use amount of the toner is 38%-42% of the use amount of the refractory cement. The width of the bamboo ribs is 2-4cm, and the bamboo ribs are laid every 30-60cm of height for a layer; and2-3 bamboo ribs are longitudinally laid on each layer, and the horizontal spacing is 80cm-120cm. The prepared novel color rammed earth wall has high compressive strength, attractive appearance and great ornamental value.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a novel colored rammed earth wall and a preparation method thereof. Background technique [0002] Traditional rammed earth is the construction technology of traditional house construction with the longest history and wide application in rural areas of our country, and it is mainly used for the construction of load-bearing walls and enclosure walls. It has the advantages of local materials, simple construction technology, low cost, energy saving and environmental protection. But there are also some deficiencies: 1. The earth wall compacted by traditional molds and wooden tampers has poor precision, and the overall appearance of the wall is not neat and compact. 2. Due to the poor density of the rammed earth wall, the waterproof and anti-seepage performance of the wall is not good, the wall is easy to peel off, and the wall foundation is more susceptible to moisture and...

AI Technical Summary

Problems solved by technology

But there are also some shortcomings: 1. The earth wall compacted by traditional molds and wooden rammers has poor precision, the overall appearance of the wall is not neat, and the compactness is poor

2. Due to the poor density of the rammed earth wall, the waterproof and anti-seepage performance of the wall is not good, the wall is easy to peel off, and the wall base is more susceptible to moisture and rot

3. Although there are bamboo or wooden strips in the wall, but the arrangement is not regular, it is still prone to cracking in the vertical direction of the wall, which will cause serious collapse

4. The appearance of the wall is monochrome, without decorative effect, and the ornamental value is poor

5. Traditional rammed earth walls use clay, glutinous rice, etc. as adhesives, which have poor anti-aging performance, low strength, and low temperature resistance

[0003] However, the existing traditional rammed earth walls are mainly made of reinforced concrete as the skeleton wall, and then the rammed earth is attached to the concrete surface through steel wire mesh or some fiber meshes as reinforcements; although the main body has high strength, the surface is easy to crack. The bonding between rammed earth, fiber mesh and steel wire mesh is not firm enough, it is easy to fall off, and soon loses its ornamental value

Or use the current pouring technology to make the wall, and then brush the clay mixed with pigment on the formed wall to achieve high strength and beautiful effect; but only brush on the surface, the weather resistance is poor, and the temperature and humidity are different. Sudden changes are also likely to cause cracking, and the ornamental performance cannot be guaranteed

Another is to add colored cement in the traditional rammed earth technology, although it can improve the strength and aesthetics to a certain extent; but there are quite high requirements for the proportion accuracy of the addition, construction speed, and demoulding process, and it is easy to appear. , holes, honeycombs, and surface cracks; at the same time, the output of colored cement is small, the price is high, the color is single, and the color is difficult to control
