| abstract |
An object of the present invention is to obtain a good crack resistance and workability by minimizing the amount of an expansion material and a shrinkage reducing agent to maximize the performance. SOLUTION: The amount of alkali in the cement is set to 0.2% or less, and an expansion material and / or a shrinkage reducing agent are mixed into the cement so that the water cement ratio is 40 parts by weight or less. Add to concrete. The performance of the expansion material and the shrinkage reducing agent is effectively exhibited by the small amount of cement, and higher crack resistance can be obtained by lowering the water cement ratio. On the other hand, it is possible to achieve a plurality of high goals such as not causing problems such as strength reduction due to excessive expansion. The water reducing agent ensures good workability even at a low water cement ratio. |
