Abstract: | From the results obtained in this study, it is concluded that the quantity of bubbles that PC-n, which is polycarboxylate having poly (n) ethylene glycol groups as side chains, introduces in concrete can be reduced when the side chains' length 'n' is designed to be longer than 25 mol. But basically it is suggested that PC-n would have the air entraining performance in itself; By using the specific AE agent and anti-foaming agent, the stable bubbles can replace the unstable ones PC-10 introduced in concrete. As a result the excellently durable concrete can be manufactured that maintains the relative dynamic Young's modulus beyond 90% till about 1,200 cycles. |
