本論文研製之透水磚是利用工業鋁渣廢料及螯合劑混和後，燒結製備成透水磚，探討其孔隙比率變化和對滲水率之影響。樣品製備以固定尺寸、重量、成分比例，改變原料粒徑大小，製備出不同樣品進行滲水效果與保水性的比較。論文包含四部分：第一部分探討製備透水磚過程環境因素對燒結過程之影響，並且透過XRD及SEM進行樣品分析，探討燒結製程對樣品之影響。第二部分測定樣品孔隙率，利用乾溼重量差計算樣品之孔隙率，比較不同粒徑尺寸對孔隙之影響。第三部分透過滲水實驗量測樣品之滲水速率，比較不同孔隙率對滲水速率的影響。第四部分透過以水濂牆結構降溫方式來評估不同粒徑尺寸樣品的降溫效果。結果發現較大粒徑尺寸的壓錠初坯樣品，若室溫下久置黏著劑容易蒸發，燒結樣品易破裂。由成分分析發現某些樣品中具有少部分硫元素，在燒結過程中易形成二氧化硫等氣體。透過滲水試驗發現固定鋁渣粒徑尺寸，不同螯合劑粒徑尺寸對樣品的孔隙尺寸大小有較大差異，且尺寸愈大則孔隙尺寸愈大，滲水效果愈佳，保水性愈差；尺寸愈小則孔隙尺寸愈小，滲水效果愈差，保水性愈佳。透過水濂牆結構降溫方式評估結果顯示保水性愈高的樣品，降溫效果愈佳。

The permeable brick developed in this paper is made by mixing industrial aluminum slag waste and chelating agent and then sintering it to make a permeable brick. The changes in porosity ratio and the impact on water permeability are discussed. Under fixed size, weight, and ingredient ratio, different samples were prepared to compare the water seepage effect and water retention by changing the particle size of the raw materials. The paper consists of four parts: the first part explores the impact of environmental factors on the sintering process during the preparation of permeable bricks, and conducts sample analysis through XRD and SEM to explore the impact of the sintering process on the samples. The second part measures the porosity of the sample, uses the difference between dry and wet weight to calculate the porosity of the sample, and compares the impact of different particle sizes on the pores. An optical microscope (OM) was used to capture the surface of the samples to measure the surface pore sizes. ImageJ software was employed to measure the surface porosity ratio, and the effects of different particle sizes on porosity were compared. The third part measures the water seepage rate of the sample through the water seepage experiment and compares the effects of different porosity on the water seepage rate. The fourth part evaluates the cooling effect of samples with different particle sizes through the cooling method of water wall structure. The results showed that if the ingot blank sample with a larger particle size is left at room temperature for a long time, the adhesive will easily evaporate and the sintered sample will easily break. From the composition analysis, it was found that some samples contain a small amount of sulfur element, and gases such as sulfur dioxide are easily formed during the sintering process. Through the water penetration test, it was found that the particle size of aluminum slag is fixed, and the pore size of the sample is significantly different with different chelating agent particle sizes. The larger the size, the larger the pore size, the better the water penetration effect, and the worse the water retention; size The smaller it is, the smaller the pore size, the worse the water seepage effect, and the better the water retention. The evaluation results of the cooling method through the water wall structure show that the higher the water retention of the sample, the better the cooling effect.
