Study of Durability of Recycled Concrete under the Environment of the Acid Rain

Article Preview

Due to the rough surface of the recycled concrete aggregates, low modulus of elasticity and large porosity, these properties led to that the apparent density, strength, physical properties and durability of the recycled concrete made by recycled aggregates are different from the Portland cement concrete, so that the standards and requirements formed about the Portland cement concrete are not entirely suitable for the recycled concrete. On the basis of the experimental studies, this paper analyzes the differences of mass loss, crushing strength and neutralization depth between the ordinary Portland concrete and recycled concrete under the influence of simulation acid rain. The results showed that there are different degrees of change between the concrete with 100% aggregates instead of recycled aggregates and the Portland concrete in mass loss, crushing strength and neutralization depth under the influence of simulation acid rain.
