| Summary: | 碩士 === 國立臺灣海洋大學 === 河海工程學系 === 106 === The concrete is in the world uses most also most widespread construction builds the material, because the concrete has the outstanding resistant to compression ability and other merits, but the concrete belongs to the brittle material, for its waterproofness has a certain timeliness. The purpose of this study was to investigate the effect of adding Vinyl acetate-ethylene (VAE) on the concrete structure. For concrete properties, try to increase the water resistance of the concrete structure and increase the service life of the steel.
The experimental results show that after the VAE additive is added, (1) because the viscosity of the VAE itself is 1500~2500 cp, the viscosity of the concrete will increase; at the same time, the temperature will decrease; the air content will increase due to the increased amount of VAE added. (2) In the case where the concrete compressive strength will slightly decrease; the splitting strength will be slightly increased. (3) The water absorption rate tends to decrease when the water ash is 0.4, and there is a significant increase when the water ash is 0.6. The water absorption rate will decrease when the water absorption rate is increased by adding 2% VAE. When the water ash is 0.4, the resistance value will decrease, and when the water ash is 0.6, the resistance value will increase. (4) It will have anti-corrosion effect after adding VAE. Corrosion rates have a tendency to decline. When added to a sufficient VAE (~2%), the water absorption rate of the concrete can be slowed down, and the activity of the corrosion potential can be lowered, the corrosion resistance effect can be improved, and the water repellency and corrosion resistance of the concrete structure can be surely improved.
