Alkali-resistant pavement brick prepared from construction waste and preparation process thereof
The invention provides an alkali-resistant pavement brick prepared from construction waste and a preparation process thereof. The pavement brick mainly comprises the following raw materials in percentage by mass: 55-65% of construction waste recycled aggregate, 7-15% of cement, 2.5-4% of an alkali-resistant complexing agent, 1.5-3.2% of a water reducing agent, 4-8% of recycled micro powder and 10.5-26.3% of water. The alkali-resistant complexing agent is mainly composed of an acidic neutralizer and an adsorbent. The alkali-resistant pavement brick has a good alkali-resistant effect, can reducethe efflorescence phenomenon in the use process of the pavement brick, and also has high compressive strength, low water absorption and excellent anti-freezing effect.
本发明提供一种建筑垃圾制备的抗碱路面砖及其制备工艺，该路面砖主要包含如下质量百分比原料：建筑垃圾再生骨料55‑65％、水泥7‑15％、抗碱复合剂2.5‑4％、减水剂1.5‑3.2％、再生微粉4‑8％、水10.5‑26.3％。其中，抗碱复合剂主要由酸性中和剂和吸附剂组成。该路面砖具有较好的抗碱效果，能减少路面砖使用过程中的“泛碱”现象，同时，该抗碱路面砖还具有较高的抗压强度，较小的吸水率以及抗冻效果优异。
