Low-carbon desert sand concrete and preparation process thereof
The invention discloses low-carbon desert sand concrete and a preparation process thereof, and belongs to the field of concrete. The concrete provided by the invention is prepared from the following components in parts by mass: 1000 to 1200 parts of graded coarse aggregate, 350 to 450 parts of medium sand, 50 to 150 parts of desert sand, 450 to 600 parts of gelling mixture, 5 to 10 parts of water reducing agent and 150 to 200 parts of water. The use amount of cement is reduced through the mixing amount of the I-grade fly ash, and the desertified desert sand is used for replacing machine-made medium sand to form the novel low-carbon desert sand concrete with the carbon footprint lower than the traditional content, so that the formation of the carbon footprint can be reduced, the engineering cost can be reduced, the environment can be protected, and resources can be saved; in addition, environment-friendly and easily available slag powder and fly ash and desertified desert sand resources can be reasonably developed, and waste materials can be reused.
本发明公开了一种低碳沙漠砂混凝土及其制备工艺，属于混凝土领域。本发明的混凝土，其组分按质量份数计包括：级配粗骨料1000‑1200份、中砂350‑450份、沙漠砂50‑150份、胶凝混合料450‑600份、减水剂5‑10份和水150‑200份。本发明通过I级粉煤灰掺入量来降低水泥用量，再次采用荒漠化的沙漠砂取代机制中砂，形成一种碳足迹低于传统含量的新型低碳沙漠砂混凝土，不但可以减少碳足迹的形成、降低工程成本、保护环境和节约资源，而且还能使环保易得的矿渣粉和粉煤灰、荒漠化的沙漠砂资源得到合理开发和废料再用。
