Compression-resistant and carbonization-resistant recycled concrete and preparation method thereof
The invention discloses compression-resistant and carbonization-resistant recycled concrete which is prepared from the following components in parts by mass: 25 to 70 parts of water, 50 to 150 parts of cement, 100 to 300 parts of sand, 200 to 600 parts of building waste stone, 10 to 20 parts of polyethylene fiber and 2 to 3 parts of a concrete modifier, and further discloses a preparation method of the compression-resistant and carbonization-resistant recycled concrete. The method comprises the steps that sand and building waste stones are put into drying equipment to be dried, and the water content of the sand and the building waste stones is reduced; putting the cement, the dried sand and the building waste stones into stirring equipment together, then adding polyethylene fibers into the stirring equipment through an inclined auxiliary pipeline, and stirring for 2-3 minutes; and adding water and the concrete modifier into the stirring equipment, and continuously stirring for 10-20 minutes to obtain the concrete product. According to the invention, the compression resistance and carbonization resistance of the concrete are improved, and the concrete can be regenerated.
本发明公开了一种抗压抗碳化再生混凝土，包括如下质量份数的组分：水25‑70份、水泥50‑150份、砂100‑300份、建筑废料石子200‑600份、聚乙烯纤维10‑20份、砼改性剂2‑3份，还公开了一种抗压抗碳化再生混凝土的制备方法，步骤包括：将砂和建筑废料石子投入烘干设备进行烘干，减少砂和建筑废料石子的含水量；将水泥以及烘干后的砂和建筑废料石子一起投入搅拌设备中，然后通过斜向辅助管道向搅拌设备加入聚乙烯纤维，先搅拌2‑3分钟；向搅拌设备中加入水和砼改性剂，继续搅拌10‑20分钟，得到混凝土产。本发明提高了混凝土的抗压抗碳化性能，并使得混凝土能够再生。
