To obtain a composition large flowability after kneading and large strength after curing and useful to be used to a closed part like a filler by forming so as to mix a water reducing agent and ethylene glycol to cement.
This non-bleeding cement composition is formed so as to mix preferably 0.1-2.0 wt.% (hereafter called %) water reducing agent of preferably a high performance water reducing agent such as a naphthalene-based alkyl aryl sulfonic acid compound, a lignin based lignin sulfonic acid compound and preferably 1.0-20.0% ethylene glycol to cement. Preferably further an expanding agent is mixed desirably by 1.0-20.0% to the cement. Further preferably an aluminum powder is mixed desirably by 0.0001-0.0005% to the cement in addition to the expanding agent. The aluminum powder acts as a foaming agent and has a function to give initial expansion.
