Preparation method of self-disintegrating concrete and self-disintegrating concrete
The invention relates to a preparation method of self-disintegrating concrete and the self-disintegrating concrete. The method comprises the following steps: weighing a concrete raw material, a pretreated component B, water, a water reducing agent and an exciting agent, uniformly mixing the concrete raw material and the component B to form a component A, uniformly mixing the water, the water reducing agent and the exciting agent to form a solution C, and uniformly mixing the solution C and the component A; wherein the component B contains at least one of f-MgO and f-CaO, the pretreatment comprises the step of coating the surface of the component B with a water-proof film, and the exciting agent is used for reacting with the water-proof film to dissolve the water-proof film. According to the self-disintegrating concrete prepared through the method, substances containing f-MgO and f-CaO are added into the concrete, meanwhile, the water-proof film is adopted for coating and isolating reaction with water, it is guaranteed that the strength of the concrete in the service period is not affected, and after the service period, the water-proof film is consumed by reaction of the exciting agent and makes contact with water to react to generate expansion and is convenient to disassemble.
本发明涉及一种自崩解混凝土的制备方法及自崩解混凝土，该方法包括：称取混凝土原材料、预处理的B组分、水、减水剂、激发剂，将混凝土原材料和B组分混合均匀后形成A组分，将水、减水剂和激发剂混合均匀形成C溶液，将C溶液与A组分混合均匀；其中，B组分中含有f‑MgO和f‑CaO中的至少一种，预处理包括在B组分的表面包覆隔水膜，激发剂用以与隔水膜反应溶解隔水膜。本发明通过该方法制备的自崩解混凝土将含有f‑MgO、f‑CaO的物质添加到混凝土中，同时采取隔水膜包覆隔绝与水的反应，保证混凝土服役期内的强度不受影响，待服役期后隔水膜被激发剂反应消耗与水接触发生反应而产生膨胀，便于拆除。
