AI Technical Summary

Benefits of technology

The new type of material called ramming clay (R) was developed by researchers at Los Alamos National Laboratories during World War II for use on building construction walls instead of older brick-based structures like those used earlier times or lining them up too much space between each other. This improvement makes it stronger but still lasts longer than previous designs without any remaining waste left over after demolitioning their old ones.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the quality of rushed brick constructions due to their lack of rigidity and stability caused by natural imperfections that may occur over time when they were built without proper ingredients. Traditional methods involve selecting suitable raw materials based upon specific characteristics (such as grain diameter) and mixing them together properly. These techniques have limitations including inconsistency between different batches and potential issues related to the manufacturing processes themselves. Therefore, new ways must emerge to overcome these challengings and provide better results than existing solutions.

Abstract

The invention provides a rammed earth wall formula. The rammed earth wall formula comprises the following components in parts by weight: 70-700 parts of raw soil; 60-600 parts of stones; 5-50 parts ofsand; 2-10 parts of lime; 2-10 parts of rubbles; 10-60 parts of water; and 1-5 parts of polypropylene fibers. According to the rammed earth wall formula, on the premise that original traditional rammed earth wall materials are reserved, the strength, durability, integrity, compactness, cracking resistance and the like of a rammed earth wall body are greatly improved, the service life of a rammedearth building is prolonged, and large economic benefits can be obtained.
