Abstract

The invention relates to a GRC (glass-fiber reinforced composite) decorative curtain wall board prepared from low-quality recycled fine aggregate and a preparation method of the GRC decorative curtainwall board. The GRC decorative curtain wall board is prepared from components in parts by mass as follows: 400-800 parts of low-alkalinity sulphate aluminium cement, 1000-1400 parts of the recycled fine aggregate, 10-40 parts of a polycarboxylate superplasticizer and 2-4 parts of alkali-resistant glass fibers. According to the GRC decorative curtain wall board prepared from the low-quality recycled fine aggregate and the preparation method of the GRC decorative curtain wall board, the GRC decorative curtain wall board is prepared from the low-quality recycled fine aggregate, the application range of the low-quality recycled fine aggregate is expanded, the utilization rate of demolition waste of buildings is increased, and the GRC decorative curtain wall board has good environment benefit,economic benefit and social benefit.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a GRC decorative curtain wall panel made of low-quality recycled fine aggregate and a preparation method thereof. Background technique [0002] With the continuous improvement of the level of urbanization in our country and the continuous expansion of the city scale, the demolition and reconstruction of old urban areas have made the area of ​​building demolition in my country continue to increase in the past 10 years. In 2017, the area of ​​building demolition in my country has reached 1.436 billion square meters. According to statistics, the output coefficient per unit area of ​​construction waste generated by the demolition of old buildings is 906.7-1335.5 kg / square meter. It is conservatively estimated that the amount of construction waste generated during the demolition of buildings in my country reached 1.6 billion tons in 2017. Among the crushed and screened products of ...
