广大农村大办沼气,沼气池防水材料必须能就地取材、土法制取才具有普及推广的现实意义。现介绍部份可用于沼气池上的简易防水材料供参考。沥青渣防水胶泥按如下体积比配成: 废沥青渣:粘土:砂:石灰=1.5∶1∶0.25∶0.25。首先将砂、石灰、粘土拌匀,加热到100℃,再把废沥青渣放入,继续加热,搅拌均匀即可使用。这种材料抗压强度达35公斤/厘米~2;抗拉强度达11公斤/厘米~2;抗渗 The vast majority of rural areas run biogas, and the biogas water-repellent materials must be capable of being locally sourced and soil-based methods have universal significance. Here are some simple waterproof materials that can be used on biogas tanks for reference. The bituminous slag waterproof clay is formulated with the following volume ratio: Waste asphalt slag: clay: sand: lime = 1.5:1:0.25:0.25. First, mix the sand, lime, and clay, heat it to 100°C, put the waste asphalt slag into it, continue heating, and stir it to use. This material has a compressive strength of 35 kg/cm~2; tensile strength of 11 kg/cm~2; impermeability
