Embodiment 1

[0036] Embodiment one manufactures solid cement handicraft

[0037] Clean the silicone mold with water mixed with 5% detergent and put it into the gypsum mold shell, pour the stirred cement slurry into the silicone mold in two times: the first time only pour a quarter of the volume of the mold Wipe and smear the inner surface of the mold with a silicone stick or a hard-bristle brush, so that the cement slurry can penetrate 100% into the fine surface of the mold, so that the formed product is complete and beautiful, without any quality defects such as pores; The remaining space in the mold is filled with cement slurry again, and the surface of the slurry is smoothed. After 2 to 2.5 hours, the demoulding can be completed; immediately after demoulding, soak the product in water once to achieve maintenance.

Embodiment 2

[0038] Embodiment two manufactures hollow cement handicraft

[0039] Clean the silicone mold with water mixed with 5% detergent and put it into the gypsum mold shell. Without closing the mold, pour the stirred cement slurry into the silicone mold in two times: the amount of the first pour into the mold is controlled to cover The thickness of the inner surface of the mold is 2 to 4 mm. Use a silicone stick or a hard brush to wipe the inner surface of the mold, so that 100% of the cement slurry can penetrate into the fine surface of the mold, so that the formed product is complete and beautiful, without pores and other aspects of quality Defects: After wiping, keep it for 10-15 minutes, then add a small amount of cement slurry and sweep it with a brush repeatedly for 20-25 minutes, so that the mold is evenly covered by the cement slurry, and the glass fiber mesh aggregate is removed before the cement slurry is solidified. Adhere to the inner surface fully, and use a brush to dip...

Abstract

The invention relates to cement slurry and a method for manufacturing a cement handicraft article therefrom. The cement slurry is prepared from the following components in percentage by weight: 49-59 percent of sulphate aluminum cement with low alkalinity, 15-25 percent of fly ash, 1-3 percent of water reducer, 4-10 percent of quick-setting additive and 12-22 percent of water. Compared with the prior art, by adding a great amount of fly ash and a special quick-setting agent in the invention, the produced handicraft article has high strength, and the problems of poor strength, easy damage, and the like are solved so that products made therefrom, such as foot bricks, desks and chairs, and the like can be paved and used in gardens to functionalize the handicraft article. By recovering a great amount of fly ash, as compared with a cement handicraft article, the production process omits burning, the production cost is low, and energy saving and emission reduction are realized. The invention has simple production process, short production cycle and high yield and can produce large-size products for substituting cement handicraft articles and resin handicraft articles.

Description

technical field [0001] The invention relates to a cement slurry and a method for manufacturing cement handicrafts from it. Background technique [0002] In the prior art, the pedal bricks or other cement handicrafts used for viewing and viewing in gardens, squares, etc. are usually made of cement, gypsum and water reducing agent. It is easy to be damaged by pedals or other methods when it is finished. And this mixed cement material can not be used for making hollow product because it can coagulate fast when it is in the mould, thereby greatly limiting its scope of use. Contents of the invention [0003] The main purpose of the present invention is to overcome the shortcoming that the early strength of handicraft made by cement slurry in the prior art is not enough, provide a kind of cement slurry and the method for making cement handicraft by it, can improve the early strength of cement handicraft greatly, avoid its was damaged early on. [0004] The present invention a...
