PROBLEM TO BE SOLVED: To obtain a nonshrinking mortar composition or a quick-hardenable nonshrinking mortar composition capable of providing a product hardly causing a subsidence or a cracking by shrinkage, excellent in quality, having excellent flowability and a strength developing property, keeping a quality even after a long-term storage, and especially having small decrease of an initial expansion coefficient. SOLUTION: This nonshrinking mortar composition in formed by compounding a cement, a swelling material, an additive, a foaming agent and a fine aggregate and regulating the foaming agent having a specific particle size to metallic aluminums in an amount of 0.001-0.01 pt. based on 100 pts. of the total amount and the quick-hardenable nonshrinking mortar composition is formed by furthermore compounding calcium aluminate and a sulfate and regulating the additive to an alkali metal carbonate in an amount of 0.001-1.0 pt. and the foaming agent to metallic aluminums in an amount of 0.001-0.01 pt. based on 100 pts. of the total amount. |
