| 摘 要： | 采用抛填骨料工艺,在混凝土浇筑或摊铺过程中均匀撒布一定的骨料,可以形成“骨料嵌锁型混凝土”.通过路面工程中的应用证明抛填骨料混凝土可以显著提高混凝土的抗压强度,7d抗折强度稍有降低,28d抗折强度略有提高.工程应用路段强度能满足抗折5.0 MPa的强度标准,此法能够明显减少路面浮浆和泌水等病害,降低水化热和收缩率,早期... |

| Abstract: | A new type of concreteaggregate interlocking concretewas prepared by a new method called scattering-filling aggregate process(i.e.scattering a certain volume fraction of coarse aggregate in the concrete during pouring or paving process).The Application of this method in the road engineering indicates that the compressive strength of concrete increases markedly,flexural strength at 7 d decreases a little while the 28 d improves slightly.The strength of concrete pavement engineering applying this method can m... |
