采用油页岩灰、粉煤灰、电石渣、石膏、石屑等作为原材料，制备了一种蒸压砖，研究了油页岩灰替代粉煤灰的比例对产品性能的影响。试验结果表明，随油页岩灰比例不断增大，蒸压砖的抗压强度、抗折强度均呈先提高后降低的变化趋势，干燥收缩值不断提高。当油页岩灰替代粉煤灰的比例为30%时，蒸压砖强度等级可达到标准JC239—2001《粉煤灰砖》中的MU15；当油页岩灰替代粉煤灰的比例为50%时，蒸压砖强度等级仍可达到MU10。
採用油頁巖灰、粉煤灰、電石渣、石膏、石屑等作為原材料，製備瞭一種蒸壓磚，研究瞭油頁巖灰替代粉煤灰的比例對產品性能的影響。試驗結果錶明，隨油頁巖灰比例不斷增大，蒸壓磚的抗壓彊度、抗摺彊度均呈先提高後降低的變化趨勢，榦燥收縮值不斷提高。噹油頁巖灰替代粉煤灰的比例為30%時，蒸壓磚彊度等級可達到標準JC239—2001《粉煤灰磚》中的MU15；噹油頁巖灰替代粉煤灰的比例為50%時，蒸壓磚彊度等級仍可達到MU10。

The autoclaved brick is prepared with the oil shale ash, the fly ash, the calcium carbide residue, the gyp?sum and the stone chips. The effect on properties of autoclaved brick is studied by changing the ratio of oil shale ash and fly ash. When the ratio of oil shale ash increases, the compressive strength and the flexural strength of au?toclaved brick increase first, and then decrease, and the drying shrinkage value keep increasing. When the ratio of oil shale ash is 30%, the strength grade of autoclaved brick could achieves MU15. When the ratio of oil shale ash is 50%, the strength grade of autoclaved brick could also achieve MU10.
