1results about How to "High resource utilization rate" patented technology

The application relates to a rapid-forming geopolymer concrete prefabricated component and a preparation method thereof. The technical scheme is as follows: 125-150 parts by mass of sodium metasilicate is mixed with 200-235 parts by mass of water to obtain a solution; the solution is stirred until it is clear, and is cooled to 5-15 DEG C to obtain an alkali activator; the alkali activator is mixed with 225-285 parts by mass of metakaolin, 60-120 parts by mass of fly ash, 400-600 parts by mass of fine aggregate and 550-850 parts by mass of coarse aggregate, is stirred, is poured, and is shaped for 10-30 min; demolding is carried out, and maintenance is carried out at normal temperature for 2-7 days to obtain the rapid-forming geopolymer concrete prefabricated component. The application has the characteristics of high solid waste resource utilization rate, short forming time, low maintenance cost and high mold flow efficiency, can be directly operated on a construction site and can be rapidly and continuously produced, and the prepared rapid-forming geopolymer concrete prefabricated component has early compressive strength.
