Abstract EN
To develop a high-performance shrinkage reducing agent, this study investigated several shrinkage reducing materials and supplements for those materials.
Fluidity and air content were satisfactory for the various shrinkage reducing materials.
The decrease in viscosity was the lowest for glycol-based materials.
The decrease in drying shrinkage was most prominent for mixtures containing glycol-based materials.
In particular, mixtures containing G2 achieved a 40% decrease in the amount of drying shrinkage.
Most shrinkage reducing materials had weaker level of compressive strength than that of the plain mixture.
When 3% triethanolamine was used for early strength improvement, the strength was enhanced by 158% compared to that of the plain mixture on day 1; enhancement values were 135% on day 7 and 113% on day 28.
To assess the performance of the developed high-performance shrinkage reducing agent and to determine the optimal amount, 2.0% shrinkage reducing agent was set as 40% of the value of the plain mixture.
While the effect was more prominent at higher amounts, to prevent deterioration of the compressive strength and the other physical properties, the recommended amount is less than 2.0%.
