研究了一种新的处理利用污泥灰的方法，将适量的污泥灰掺入黏土当中制成一种新的混合材料。为了研究污泥灰改性黏土混合材料的抗压强度特性，通过击实试验、无侧限抗压强度试验，确定了污泥灰改性黏土混合材料的击实曲线及抗压强度值。采用混合材料和纯黏土各自最大干密度值制备试样，进行无侧限抗压强度试验。试验测得5％、10％、15％污泥灰含量的混合材料试样最大干密度分别为1．60g／cm3、1．56g／cm3、1．5g／cm3，最优含水率分别为20．5％、18．9％、17．9％，而不含污泥灰的纯黏土对比试样，其最大干密度为1．66g／cm3，最优含水率为22％，试验结果表明：随着污泥灰量的添加，试样的最优含水率、最大干密度、无侧限抗压强度均有所减少，且随着污泥灰含量的增大，其值随之逐渐减少。

This paper presents a new method of disposal and utilization of sludge ash .Moderate sludge ash mixed with clay , which made a new hybrid materials .In order to study the compressive strength characteristics of sewage sludge ash modified clay hybrid materials , carry out the compaction test , unconfined compressive strength test , de-termine the compaction curve and compressive strength of sludge ash modified clay hybrid materials value .The maximum dry density of the mixed materials and pure clay was used to make the experimental samples for the un -confined compression strength test .The maximum dry density of three kinds of sewage sludge ash content ( 5%、10%、15%) are 1.60g/cm3 , 1.56g/cm3 ,1.5g/cm3 ,the optimum water content are 20.5%, 18.9%, 17.9%, and the contrast sample of pure clay with 0%sludge ash , the maximum dry density is 1.66g/cm3 , the optimum water content is 22%.This test results show that , with the addition of sewage sludge ash , the optimal water sample rate, maximum dry density , the unconfined compressive strength are decreased and with the increase of sludge ash content , the value of unconfined compressive strength will be gradually reduced .
