采用一种国产生物蛋白酶和熟石膏粉作为外掺料,对黑色泥炭质水泥加固土进行了不同配比条件下3个龄期的加固土室内无侧限抗压强度的正交试验研究,对试验结果进行了方差和显著性分析,还进行了试块在硫酸钠溶液中浸泡的试验,验证了熟石膏粉和该种蛋白酶具有提高泥炭质水泥土试块强度的效果,试块具有一定的抗硫酸盐侵蚀的能力。
Using a kind of domestic bio-protease and plaster powder as external admixture, the orthogonal experimental study on the unconfined compressive strength of reinforced soil with different ratios of black soil-peat cement at three different ages was conducted. The test results were analyzed for variance and significance, and the test block was soaked in sodium sulfate solution. It was verified that the plaster powder and the protease had the effect of improving the strength of peat soil test blocks. The test block had certain Resistance to sulfate attack.
