Method for sealing carbon dioxide in inorganic solid waste mineralized concrete
The invention discloses a method for sealing carbon dioxide by inorganic solid waste mineralized concrete. The method comprises the following steps: preparing inorganic solid waste concrete; carbon dioxide is injected into the concrete, pressure data of each moment and the corresponding moment are recorded, the sealed quantity is obtained according to the pressure data, the sealed quantity data correspond to the moments, an original data sequence is formed, a GM prediction model is established, and a prediction result of the GM prediction model is compared with an actual result to output a relative error proportion; and performing interval division on the relative error proportion, and representing the divided interval as a state. According to the invention, the Markov chain is adopted to predict the sequestration amount according to the current data, and the carbon dioxide output amount is adjusted according to the predicted sequestration amount so as to ensure that the concrete can sequestration carbon dioxide to the maximum extent; the water, the monocalcium silicate and the limestone are used as concrete materials and can improve the sealing capacity of carbon dioxide.
本发明公开了一种无机固废矿化混凝土封存二氧化碳的方法，包括以下步骤：制备无机固废混凝土；向混凝土中注入二氧化碳，并记录每个时刻和对应时刻的压力数据，根据压力数据得到已封存量，将已封存量数据与时刻相对应，形成原始数据数列，建立GM预测模型，并将GM预测模型预测的结果与实际结果进行比较输出相对误差比例；将相对误差比例进行区间划分，将划分后的区间表示为状态。本发明采用马尔科夫链根据当前的数据对封存量进行预测，根据预测后的封存量来调整二氧化碳输出量，以保证混凝土能最大限度的封存二氧化碳，利用采用未水化的氧化镁材料、粉煤灰，水、硅酸一钙和石灰石作为混凝土材料能提高二氧化碳的封存能力。
