Cement-modified activated carbon composite cementing material, preparation method thereof and concrete
The invention relates to a cement-modified activated carbon composite cementing material, a preparation method thereof and concrete. The cement-modified activated carbon composite cementing material comprises cement and modified activated carbon, the cement-modified activated carbon composite cementing material comprises the following components in percentage by mass: 40-60% of modified activated carbon. The modified activated carbon is prepared by carbonizing coffee skin, mixing with an activating agent, and heating and activating. The modified activated carbon in the composite cementitious material takes coffee skin as a raw material, so that waste biological resources are fully utilized, the cost is low, the composite cementitious material is economical and environment-friendly, and the utilization of solid wastes is realized. According to the invention, cement is partially replaced by modified activated carbon, the obtained composite cementing material is used in a building material, has better corrosion resistance in a seawater environment with higher chloride ion concentration, and can solve the problems of concrete cracking and steel bar corrosion caused by seawater infiltration into a building in a marine surrounding environment.
本发明涉及一种水泥‑改性活性炭复合胶凝材料、其制备方法及混凝土，水泥‑改性活性炭复合胶凝材料包括水泥，以及改性活性炭；按照质量分数计，水泥‑改性活性炭复合胶凝材料中包括40‑60％的改性活性炭。改性活性炭由咖啡皮经过炭化处理、与活化剂混合后加热活化处理制备得到。本发明的复合胶凝材料中的改性活性炭以咖啡皮为原料，充分利用了废弃生物资源，成本低廉，经济环保，实现了固体废弃物的利用。本发明以改性活性炭部分代替水泥，得到的复合胶凝材料用于建筑材料中，在氯离子浓度较高的海水环境中具有较好的耐腐蚀性能，能够解决海洋周围环境中建筑物被海水渗入造成的混凝土开裂以及钢筋腐蚀的问题。
