Ground injection materials used for reinforcing soft ground are classified into solution type and non-solution type. Generally, the water glass type of the solution can change the solidification time arbitrarily, but its early strength and durability are low. Therefore, a water glass-based injection material that has high strength and durability and can be used in a wide range of applications is required. Thus, we report the basic properties of ground injection material using special water glass and special organic hardener solution.
