The invention discloses a curing method of a cement product. The method concretely comprises the following steps: 1) adding a curing agent into water, oscillating for dispersing to obtain a curing agent dispersion, adding cement into the curing agent dispersion, and stirring to obtain a slurry; 2) putting the slurry into a magnetic field, stirring under the action of the magnetic field, then pouring the slurry into a mold, carrying out steam curing in a curing chamber, spraying distilled water onto the surface of the cement product after each time of curing is finished, then carrying out steamcuring, and repeating the processes for 3-4 times; 3) standing the demolded cement product in the curing chamber for secondary curing, and continuously introducing a carbon dioxide/nitrogen mixed gasinto the curing chamber in the curing process; and (4) cooling the cement product after the secondary curing is finished, and naturally curing the cement product for 3-5 d. The cement product finallyobtained by curing using the curing method has the advantages of smoothness and no sand holes of the internal and the surface, high overall load weight, high practicability and excellent promotion and application prospects.
本发明公开了一种水泥制品的养护方法,具体方法如下:1)养护剂加入到水中,振荡分散后制得养护剂分散液,然后将水泥加入到养护剂分散液中,搅拌后制得浆料;2)将浆料置于磁场中,在磁场作用下进行搅拌,然后将浆料浇注到模具中,在养护室进行蒸汽养护,每次养护结束后往水泥制品表面喷洒蒸馏水,然后再进行蒸汽养护,如此往复3‑4次;3)将脱模后的水泥制品静置在养护室中进行二次养护,在养护过程中,往养护室中持续通入二氧化碳/氮气混合气体;4)二次养护结束后,将水泥制品冷却后再经自然养护3‑5d即可。通过该养护方法进行养护,最终得到的水泥制品的内部和表面平整、无沙眼,整体载荷重量较高,实用性强,具有很好的推广应用的前景。
