| Summary: | 碩士 === 正修科技大學 === 營建工程研究所 === 102 === This study is to make use of the gravel sediment mud , after treated waste liquid crystal display, dried mudstone all crushed into a powder, again combined with iron oxide, sodium bicarbonate, carbon powder and flux agent etc. after dry naturally compacts made of brick, then heating segmented sintered red brick, base mechanics features of the brick through tests of compressive strength, water absorption and density, and to explore content of gravel sediment mud, mudstone, flux, the relationship between compressive strength and water absorption rate.
Experimental results have proven that:
1.Fluxes used iron oxide, sodium bicarbonate, carbon powder add the amount of toner, adding volume by 1% to 3%, mudstone fixed usage.
Compressive strength increases with increasing temperature, and water absorption and bulk density with sintering temperature decreases, in SM25-M10-TFT65-Fe0, SM25-M10-TFT64-NaH1, SM25-M10-TFT63-NaH2, SM25-M10-TFT62-NaH3 four kinds of ratios, 900 ℃ during sintering，it meets the requirements of three kinds of bricks, 1000 ℃ during sintering, in SM25-M10-TFT64-NaH1、SM25-M10-TFT63-NaH2 and SM35-M10-TFT54-NaH1 three kinds of ratios, the compressive strength and water absorption on the Meets two kinds of tiles required, Its density is less than 1.8 g/cm3.
2.gravel sediment mud adding volume increases 25% to 45%,.mudstone usage fixed 10%, fluxes volume fixed usage.
Compressive strength increases with increasing temperature, but with the addition of increased gravel sediment mud decreases. in 900 ℃ during sintering, SM25 -M10-TFT64-NaH1、 SM25-M10-TFT63-NaH2、SM25-M10-TFT63-Fe2 and SM25-M10- TFT62-NaH3 ratios, and in 1000℃ during sintering, SM35-M10-TFT54-NaH1 、SM25-M10-TFT64-NaH1 etc ratios they met the requirements of three kinds of bricks, on the compressive strength and water absorption Its density is less than 1.8 g/cm3.
