I need the type of soil and general specification
You need to have a soil type that has the consistency of sand. Anything dry and grainy... Stay away from clayish substances where the soil tends to stick together because the cement cannot go through them. Usually the ratio I can give for a good building block is about 6 parts of sand, 2 parts cement and 1 part of water (or less depending on the consistency). It should feel like the consistency where it can be easily molded but not soggier than brownies. Use portland cement...
