Carbon-absorbing and carbon-sequestration concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses carbon-absorbing and carbon-sequestration concrete and a preparation method thereof. The carbon-absorbing and carbon-sequestration concrete comprises Portland cement, silica fume, mineral powder, fly ash, coarse aggregate, pottery sand, natural sand, micro-nano carbon dioxide bubble water, sodium hydroxide and a water reducing agent, wherein the dissolution rate of micro-nano carbon dioxide bubbles in the micro-nano carbon dioxide bubble water in water is greater than 95%; the preparation method comprises the following steps: mixing the cement, the fly ash, the mineral powder, the sodium hydroxide, the ceramsite, the recycled aggregate, the gravel, the natural sand, the water reducing agent and the micro-nano carbon dioxide bubble water, and uniformly stirring to obtain the carbon-absorbing and carbon-sequestration concrete. The carbon-absorbing and carbon-sequestration concrete has the advantage that the carbon dioxide absorbing and sequestration effect of the concrete is improved; the preparation method has the advantages that the operation steps are simple, raw materials are easy to obtain, and the method is suitable for large-scale application.
本申请涉及混凝土领域，具体公开了一种吸碳固碳混凝土及其制备方法。吸碳固碳混凝土包括硅酸盐水泥、硅灰、矿粉、粉煤灰、粗骨料、陶砂、天然砂、微纳米二氧化碳气泡水、氢氧化钠和减水剂，所述微纳米二氧化碳气泡水中微纳米二氧化碳气泡在水中的溶解率大于95%；其制备方法为：将水泥、粉煤灰、矿粉、氢氧化钠、陶粒、再生骨料、碎石、天然砂、减水剂和微纳米二氧化碳气泡水混合，搅拌至均匀后得到吸碳固碳混凝土。本申请的吸碳固碳混凝土具有提高混凝土吸收固定二氧化碳的效果优点；本申请的制备方法具有操作步骤简单、原材料易得、适合大规模应用的优点。
