Retarding method of unfired building material prepared from original-state shield muck
The invention relates to a delayed coagulation method of an unfired building material prepared from undisturbed shield muck. The delayed coagulation type unfired building material prepared from the undisturbed shield muck comprises the following raw materials in percentage by mass: 55-80% of undisturbed shield muck, 15-40% of an alkali-activated cementing material, 1-6% of water and 0-1.5% of a retarder, the content of the retarder is greater than 0. According to the invention, an organic compound and/or an inorganic high-molecular polymer are/is used as a retarder to form a composite polymer or a condensate which is attached to the surfaces of muck particles, so that the formation of the strength of a muck solidified body is delayed, and the retarding effect is achieved. Under the condition that the strength is not influenced, the initial setting time of the original shield muck unfired building material can be prolonged to 1h-6h. The invention provides a new method for controlling the setting time of the shield muck unfired building material based on alkali excitation, and has important practical significance.
本发明涉及一种原状盾构渣土免烧建筑材料的缓凝方法，该缓凝型盾构渣土免烧建筑材料包括如下质量百分比的原料：原状盾构渣土55％‑80％、碱激发胶凝材料15％‑40％、水1％‑6％和缓凝剂0％‑1.5％；缓凝剂含量＞0。本发明以有机化合物和/或无机高分子聚合物作为缓凝剂，形成复合聚合物或凝聚物附着在渣土颗粒表面，延缓渣土固化体强度的形成，从而达到缓凝的效果。本发明在不影响强度的情况下，可将原状盾构渣土免烧建筑材料的初凝时间延长至1h‑6h。本发明为基于碱激发的盾构渣土免烧建筑材料的凝结时间控制提供了一种新方法，具有重要的现实意义。
