Ecological slope protection material and preparation method thereof
The invention provides an ecological slope protection material which comprises the following components in parts by weight: 20-40 parts of acid activated red mud, 50-80 parts of cement, 0.5-2 parts of a foaming agent and 1-3 parts of polyaluminum chloride. The red mud is acidified, the acidified solid particles have many pores and increased specific surface area (the specific surface area of the particles which are not activated before acidification is 5.3177 m < 2 >/g, and the specific surface area of the particles prepared by acid activation is 33.2132 m < 2 >/g), and the specific surface area of the solid particles is increased, so that the adsorption effect on water pollutants is relatively good; and when the ecological slope protection material is placed on a river slope through fixing devices such as a gabion screen and the like, pollutants in river water can be reserved in pores in the ecological slope protection material, and the content of the pollutants in the river water can be effectively reduced, so that the water quality is improved, and the eutrophication degree of a water body is reduced.
本发明提出了一种生态护坡材料，按重量份计，包括如下组分：酸活化赤泥20‑40份、水泥50‑80份、发泡剂0.5‑2份和聚合氯化铝1‑3份。本发明通过将赤泥酸化，利用酸化后的固体颗粒的孔隙多、比表面积增大(酸化前未经活化的颗粒比表面积为5.3177m2/g，而酸活化制备的颗粒比表面积为33.2132m2/g)，并且由于固体颗粒比表面积的增大，使得其对于水体污染物的吸附效果较好，将其通过如石笼网等固定装置放置于河道坡面上时，河水中的污染物可以被留在生态护坡材料内的孔隙中，能够有效降低河水中的污染物含量，从而提升水质，降低水体富营养化程度。
