Abstract

The invention discloses a high-performance ardealite fiber composite material and a preparation method thereof. According to the preparation method, a close packing design method is utilized to optimize the matrix mix proportion of the ardealite composite material, and then organic fibers are doped into the optimized matrix, so that the high-performance ardealite fiber composite material is prepared. The matrix of the composite material is composed of the following components in parts by weight: 100 parts of semi-hydrated phosphogypsum, 5 to 50 parts of slag powder, 5 to 40 parts of fly ash, 5 to 20 parts of cement, 0.05 to 0.5 part of a special retarder for gypsum, 0.1 to 0.5 part of a polycarboxylic acid water reducer and 40 to 120 parts of water. The mixing amount of the organic fibers of the composite material is 0.001 to 0.0006 (by volume fraction). The high-performance ardealite fiber composite material disclosed by the invention has the characteristics of good construction performance, high strength, water resistance, moisture resistance and low density, and has a wide application range.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-performance phosphogypsum fiber composite material and a preparation method thereof. Background technique [0002] The annual discharge of phosphogypsum in my country has reached about 50 million tons. Due to the bottleneck of resource utilization technology, the accumulated stockpile exceeds 200 million tons. At present, the comprehensive utilization rate of phosphogypsum is only about 30%. Usually, phosphogypsum is disposed of by stacking in the open air or pouring into the sea, which not only requires a large amount of land occupation, but also contains phosphorus, fluorine and other harmful substances in the phosphogypsum that will pollute the surrounding atmosphere, soil and groundwater. How to manage and utilize phosphogypsum is an urgent problem to be solved. [0003] Phosphogypsum is properly purified, dried and calcined to remove free water and crysta...
