Retarder for recycled aggregate mortar, and preparation method of retarder
The invention discloses a retarder for recycled aggregate mortar, and a preparation method thereof, and relates to the technical field of building materials, wherein every 100 parts by weight of the retarder for the recycled aggregate mortar is prepared from the following components in parts by weight: 2.5 to 3.5 parts of sodium gluconate, 4.5 to 5.5 parts of white sugar, 1.5 to 2.5 parts of citric acid, 2 to 3 parts of amino trimethylene phosphonic acid, 2 to 3 parts of modified phosphogypsum, 1.5 to 2 parts of steel slag micro powder and the balance of water. The retarder for recycled aggregate mortar has the advantages of good compatibility with a cementing material, strong water retention and plasticity retention, prolongation of the setting time of the recycled aggregate mortar, prolongation of the operation time, and improvement of the compressive strength of the hardened mortar.
本发明公开了一种再生骨料砂浆用缓凝剂及其制备方法，涉及建筑材料技术领域，再生骨料砂浆用缓凝剂，每100重量份缓凝剂包括以下重量份的组分：2.5‑3.5份葡萄糖酸钠、4.5‑5.5份白糖、1.5‑2.5份柠檬酸、2‑3份氨基三甲叉膦酸，2‑3份改性磷石膏、1.5‑2份钢渣微粉、余量为水。本发明的再生骨料砂浆用缓凝剂具有与胶凝材料的相容性好，保水和保塑性强，能延长再生骨料砂浆的凝结时间，延长操作时间，提高砂浆硬化后的抗压强度的优点。
