Embodiment Construction

[0009] The present invention will be further described below in conjunction with specific embodiment:

[0010] A lightweight aggregate concrete protective airtight door, which consists of the following components in terms of weight percentage: 110 parts of low-alkalinity sulphoaluminate cement, 6 parts of thickening powder, 120 parts of expansion powder, 200 parts of machine-made sand, alkali-resistant 80 parts of glass fiber staple, 50 parts of micro-silica fume, and at the same time, in order to improve the strength and weather resistance, it also includes 10 parts of nano-titanium powder and 40 parts of carbon fiber staple. Before forming, the above raw materials are stirred evenly and then formed.

[0011] Among them, the machine-made sand is made from limestone tailings and iron tailings. The thickened powder produced by Huzhou Anji Bentonite Company is used. The main raw materials are bentonite and kaolin. The thickened powder has high water retention, good workability, ...
