摘要： PROBLEM TO BE SOLVED: To provide a low-strength mortar filling which is a filling filled into the cavity of ground and is used instead of an air mortar filling having such a limitation that it is difficult to use an existing ready-mix concrete plant.
SOLUTION: The low-strength mortar filling used is a mortar prepared by mixing cement with fly ash, SHIRASU (a kind of pumiceous sand), and water. The filling contains at least 800 kg/m
3 SHIRASU. The mortar flow of the filling is set at 180 mm or higher. The weight ratio SH/P is at least 2.5 (wherein SH is SHIRASU, and P is the powder comprising the cement and an inorganic powder). The weight ratio FA/P is 0.7 or higher (wherein FA is the inorganic powder and P is as defined above). The weight ratio W/C is 4.0 or higher (wherein W is water, and C is the cement).
