Utilizing the thickening ability of threadlike micellar solution, which exhibits Maxwell-type viscoelastic behavior, we have developed a new thickening agent VISCOTOP for civil engineering usages. In contrast to usual thickening agent, VISCOTOP is able to increase viscosity of fresh concrete mixture without hardening retardation. In addition, we have found that VISCOTOP has various potential abilities in civil engineering usages because of its gel-like properties produced in the water. The cement slurry protected with VISCOTOP has unique properties; it can be poured into water without diffusion; it does not permeate into porous ground. The elastic property of VISCOTOP solution protects falling down of weak sand wall.
