Preparation method of C40 anti-freezing concrete and inorganic coating spraying process
The invention discloses a preparation method of C40 anti-freezing concrete and an inorganic coating spraying process. The preparation method comprises the following steps: pouring sand and the stonesinto respective raw material bins to be pre-homogenized, wherein the pre-homogenization time is 5-10 min, and the stirring speed is 5-10 r/min; stirring and mixing the pre-homogenized sand and stonesin a forced stirrer for 2 minutes at the stirring speed of 3-6 r/min; after mixing, adding cement, fly ash and a polycarboxylate superplasticizer into a forced stirrer, stirring for 5 minutes, then adding an XT-HPA environment-friendly high-permeability inorganic crystal waterproofing agent, and stirring for 2 minutes so as to obtain a concrete test block; and maintaining the concrete test block in water for 28 days, and spraying an XT-HPS environment-friendly high-permeability enhanced sealant. The inorganic coating and the outer inorganic coating are added, so that the waterproof and adhesive properties of the concrete are improved, and the frost resistance and durability of the concrete are improved.
本发明公开了一种C40抗冻混凝土制备方法及无机涂层喷涂工艺。将砂子、石子倒入各自原材料仓进行预均化，预均化的时间为5‑10min，搅拌速度为5‑10r/min；预均化后的砂子、石子放在强制搅拌机内搅拌混合2min，搅拌速度为3‑6r/min；混合后在强制搅拌机内加入水泥、粉煤灰、聚羧酸减水剂搅拌5min，后加入XT‑HPA环保型高渗透无机结晶防水剂搅拌2min，即得混凝土试块；将混凝土试块在水中养护28天，喷涂XT‑HPS环保型高渗透增强密封剂。本发明加入无机涂层和外涂无机涂层，提高混凝土的防水和粘结性能，从而提高混凝土的抗冻耐久性。
