我队把石灰和黄土混合试验成所谓二合土来做90马力柴油机的水泥底座。这是目前在水泥不足情况下贯彻土洋并举方针的一种好方法。二合土用石灰与黄土以1与2之比混合而成。首先过筛清除砂石,然后将石灰全部浸湿,搅拌均匀,再和黄土混合搅拌,到拌匀为止。照柴油机底座面积挖一个3米×1．5米×2米(长 Our team mixed the lime and loess into a so-called two-loam hybrid cement base for a 90-horsepower diesel engine. This is a good way to implement the principle of combining both native and foreign cultures with the current lack of cement. Combine with lime and loess to 1 and 2 ratio from the mixture. First, sieve to remove sand and sand, and then all wet lime, stir, and then mixed with loess to mix well. According to the diesel engine base area dug a 3 m × 1.5 m × 2 m (long
