摘要： PROBLEM TO BE SOLVED: To provide a method for preparing nonshrinkage AE concrete with which the shrinkage factor of an obtained hardened product is suppressed to 50 μm or less and the hardened product can be made into nonshrinkage substantially without adversely affecting the fluidity or the amount of entrained air of the prepared AE concrete, and the compression strength or neutralization suppression of the obtained hardened product.SOLUTION: In the preparation of AE concrete using cement, fine aggregate, coarse aggregate, a dry shrinkage reducing agent, an expander, a cement dispersant, an air amount adjusting agent and water, high-early-strength portland cement is used as cement in a specific ratio, and specific blast furnace slag fine aggregate is used at least as a part of fine aggregate in a specific ratio. Concurrently, the dry shrinkage reducing agent and the expander are used in a specific ratio and the unit amount ratio is controlled into a specific range.
