LOW-STRENGTH MORTAR COMPOSITION AND PORE-FILLING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a low-strength mortar composition in which fluidity is excellent and both underwater inseparability and material resistance can sufficiently be secured, and also to provide an inexpensive pore-filling material using the same. SOLUTION: A thickening admixture is blended into the low-strength mortar composition having a water/cement ratio of 100-250% at a rate of 0.5-5.0 wt% per unit amount of water to suppress bleeding by increasing viscosity while maintaining a required fluidity. The thickening admixture contains (A) a first water-soluble low-molecular-weight compound selected from cationic surfactants and (B) a second one selected from anionic aromatic compounds.
