preparation example Construction
[0049] The volume of the foam prepared by the preparation method of the above-mentioned foaming material is fine and uniform, and the addition of the water-repellent agent makes the foam form similar to smooth microbeads. The interface between the mixed solution and the foam forms a thin film, which is flexible and elastic, plays a lubricating role and has a good water retention effect, and can also effectively improve the fluidity of the foaming material during pouring.
[0050] see image 3 , the shell is prepared by the following method:
[0051] S1111. Prepare raw materials according to the shell formula, mix the above raw materials, and stir evenly to obtain a mixture.
[0052] Wherein, in terms of mass percentage, the above shell formula contains the following components:
[0053] 12%~16% cement, 8%~10% fly ash, 10%~15% ceramsite graded aggregate, 5%~10% modified perlite, and the rest is slag, water sand or stone Nitrate.
[0054] Among them, 12%~16% of cement is the...
