A kind of planting concrete material prepared by wet grinding potassium feldspar and phosphorus tailings and preparation method thereof

Abstract

The invention relates to a planted concrete material prepared by wet grinding potassium feldspar and phosphorus tailings and a preparation method thereof. The planted concrete material is composed of the following components in parts by weight: 22-33 parts of coarse aggregate, 5.3-7.154 parts of cement, 1.378-1.86 parts of water, 0.0159-0.0214 parts of polycarboxylate water reducing agent, 0.795-1.323 parts of wet-milled phosphorus tailings powder, 0.795-1.323 parts of wet-milled potassium feldspar powder, and 1.1528-1.3675 parts of 3 wt% oxalic acid solution. In the present invention, phosphorus tailings and potassium feldspar are mixed into the cementitious material after wet grinding, which can improve the mechanical properties of the cementitious material in the later stage; Dissolution K + , P + , in order to play the role of slow-release fertilizer, so as to continuously provide necessary mineral elements for the growth of plants; in the later stage, the pH value of the system is effectively reduced by acid spraying and alkali reduction, which provides good growth conditions for plants, which is conducive to improving the performance of planted concrete materials. comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of ecological concrete, in particular to a plant concrete material prepared by wet grinding potassium feldspar and phosphorus tailings and a preparation method thereof. Background technique [0002] While human civilization is advancing by leaps and bounds, it is also ruthlessly destroying the common homeland on which human beings and other living things depend. In the development of water conservancy, transportation, energy, and urban expansion, the natural topography and the original vegetation cover are destroyed, resulting in soil erosion, local microclimate changes and biological chains being cut off. In the face of the serious deterioration of the ecological environment, the large-scale use of traditional concrete obviously does not meet the requirements of a resource-saving and environment-friendly society, so the country is constantly committed to the development of new energy sources and synthetic n...

AI Technical Summary

Problems solved by technology

[0006] The preparation process of the above-mentioned planting concrete is relatively complicated and the cost is relatively high. The various mineral elements required for plant growth need to be supplemented by artificially prepared nutrient substrates in the later stage. Therefore, the management of plant growth conditions in the later stage requires a lot of manpower and material resources.
