摘要
对铸造废砂取代天然细集料制成水泥混凝土的性能进行了初步探讨,对处理后和未经过处理的铸造废砂对混凝土性能(抗压强度和抗折强度)的影响进行了对比。试验结果表明,铸造废砂经过处理后对混凝土的抗压和抗折强度的提高,具有明显的效果。并对其作用机理也进行了初步的探讨。
The article presents an experimental study on the application of used sand in concrete to replace mineral fine aggregates and compares the effect of the used sand with processing in concrete and without processing. The test results show a noticeable enhancement, in both compressive strength and flexural strength of concrete along with increase of the replacement by used sand with processing, in comparison to without processing. The article discusses reason of the phenomenon above-mentioned.
