Embodiment Construction

[0018] serial number

[0019] After the above batching preparation, the preparation methods of three implementation batching schemes of the hollow block of the present invention are as follows:

[0020] The first step: Put 57-67% of coal ash and 10-15% of cement into the wheel mill;

[0021] Step 2: Add 20-30% of clay ceramsite and 3%-4% of water in the total weight of the mixture, and forcefully stir until uniform;

[0022] Step 3: Put the evenly stirred mixture into the hollow block forming machine, and shape it by high-frequency vibration;

[0023] The fourth step: the formed hollow block is covered with a film, and it is closed and stagnant for 24 hours;

[0024] Step 5: Place the closed and stagnant hollow block into a steam curing kiln for 8 hours to complete the finished hollow block.

[0025] The present invention adopts the above-mentioned three kinds of batching implementations and the hollow block manufactured by the preparation method, as shown in Figur...

Abstract

The small hollow flyash block is made with flyash 57-67 wt%, clay haydite 20-30 wt%, cement 10-15 wt%, and water 3-4 wt%. The production process has semi-finished product closing and steam curing to raise the product performance stability, and the product has four row hole structure, several wall layers and air layer to increase heat resistance and lower the heat transfer coefficient K to below 1.0W / sq m.k. The building with the small hollow flyash block has high energy saving effect.

Description

technical field [0001] The invention relates to a non-metallic building material and a preparation method thereof, in particular to a small-sized hollow block with good air permeability and a preparation method thereof, which adopts fly ash as the main component. Background technique [0002] At present, there are many hollow blocks with good thermal insulation, air permeability, sound insulation, moisture resistance and other performances in the market and their preparation methods, such as the lightweight hollow brick and its preparation method described in the patent No. 02132459.0 or the patent No. 200410073890.5. A small hollow block made of polystyrene particles and a preparation method thereof, the former is more complex in composition, structure and production process, and the manufacturing cost is higher; although the latter has improved compared with the former, its composition is still relatively large. Contents of the invention [0003] The object of the presen...
