Special concrete product and preparation method thereof
The invention relates to the field of concrete, and particularly discloses a special concrete product and a preparation method thereof.The special concrete product is prepared from, by weight, 600-850 parts of coarse aggregate, 400-500 parts of fine aggregate, 180-300 parts of cement, 150-160 parts of water, 45-60 parts of phosphorus slag powder, 60-80 parts of N-methyl pyrrolidone and 30-40 parts of alkali metal salt; and the preparation method comprises the following steps: uniformly mixing the alkali metal salt, the N-methyl pyrrolidone, the coarse aggregate, the fine aggregate, the cement, the water and the admixture to obtain the special concrete. and preparing the special concrete into a product, curing, soaking the prepared product into a decomplexing solution, taking out, and drying until no water drops, so as to obtain the special concrete product. The special concrete product provided by the invention has the advantage of higher permeable rate, and the preparation method provided by the invention can improve the water permeability of the concrete.
本申请涉及混凝土领域，具体公开了一种特种混凝土制品及其制备方法，特种混凝土制品由以下重量份的组分组成：粗骨料600‑850份，细骨料400‑500份，水泥180‑300份，水150‑160份，磷矿渣粉45‑60份，N‑甲基吡咯烷酮60‑80份，碱金属盐30‑40份；其制备方法为：将碱金属盐、N‑甲基吡咯烷酮、粗骨料、细骨料、水泥、水以及掺和剂混匀，得到特种混凝土；然后将特种混凝土制成制品，经过养护后，将制得的制品浸泡到解络溶液中，再取出干燥至无水滴下，得到特种混凝土制品。本申请的特种混凝土制品具有透水率更高的优点，本申请的制备方法能提高混凝土透水性。
