Porous soil block

Abstract

A porous soil block is provided to improve moldability, to prevent the separation of materials using enough mixing water and to secure excellent porosity and high strength by preventing a soil binder from falling in vibrating compaction. CONSTITUTION: A porous soil block includes aggregates, a soil binder, and superficial porous natural fiber. The soil binder includes soil, blast furnace slag fine powder, and blast furnace slag cement. The soil binder includes 38-52 weight% of the blast slag cement, 30-40 weight% of the blast slag fine powder, 8-26 weight% of the soil, and 4-8 weight% of anhydrous gypsum. The soil includes clay, loess, sandy soil, or kaolin.

Description

technical field [0001] The present invention relates to a porous mud block used for river revetments and retaining walls, and more specifically, to a porous mud block that ensures both structural stability and ecological stability and is suitable for dry system production. Background technique [0002] There are wet system production method and dry system production method in the production method of porous mud block. The wet system production method is a method of using concrete with slump, and its advantages are that it is easy to produce various shapes and has high strength. But one mold can only produce one product, which has low productivity and high unit price. [0003] The dry system production method uses concrete without slump to produce multiple products with one mold, and its unit price is low, so it is widely used in China. [0004] However, the porous clay made by the dry system production method needs to add a large amount of compounding water to prevent mate...

AI Technical Summary

Problems solved by technology

[0004] However, the porous clay made by the dry system production method needs to add a large amount of compounding water to prevent material separation and improve formability when mixing with its product samples. At this time, due to the shaking of the product during molding, the clay binder leaks out , so that the gap clogging phenomenon occurs

As a result, it is impossible to fully perform the function of ecological mud blocks, and it is impossible to make plants grow in the gaps of mud blocks

On the other hand, if the amount of compounding water is insufficient, sufficient compounding cannot be achieved, and problems such as material separation and low formability occur.
