preparation example Construction

[0043] In one embodiment, the preparation method of the porous structure material at least includes the following steps:

[0044] Weigh cement, alkali slag, ceramic sludge, fiber, aluminum powder and water according to the above-mentioned formula components;

[0045] dry-blending the cement, alkali slag, ceramic sludge, and fibers to obtain a first material;

[0046] wet-mixing the water and the first material to obtain a second material;

[0047] Mixing the aluminum powder and the second material to obtain a third material;

[0048] The third material is fired, and the temperature is raised to 150°C-220°C during firing, kept for 15min-30min, then continued to be heated to 850°C-950°C, kept for 25min-50min, and then cooled to room temperature to obtain the described Porous structure material.

[0049] The above-mentioned preparation method will be further described in detail below.

[0050]Preferably, the average particle size of the cement is 30 μm to 60 μm, and the stren...

Embodiment 1

Abstract

The invention discloses a porous structure material, a preparation method and application thereof. The porous structure material comprises the following components by weight: 20-60 parts of cement; 300-500 parts of alkaline residue; 0.5-1.0 part of fiber; 500-750 parts of ceramic waste sludge; 0.3-0.8 part of aluminum powder; and 80-160 parts of water. Specifically the raw materials are fired to form the porous structure material. The material provided by the invention has a volumetric weight of 400-700kg / m<3>, compressive strength of greater than or equal to 8MPa, breaking strength of more than or equal to 3MPa, and thermal conductivity of less than or equal to 0.11W / (m.K), and has good frost resistance, thus being applicable to heat and sound insulation of buildings.

Description

technical field [0001] The invention relates to the technical field of industrial waste recycling, in particular to a porous structure material and its preparation method and application. Background technique [0002] In recent years, the country's requirements for energy conservation and emission reduction have continued to increase, and the heat transfer coefficient limits of exterior walls, roofs and other enclosure structures have been further reduced, and the national energy-saving design standards for residential buildings, public buildings, and rural residential buildings have been revised The provincial and municipal building energy efficiency design standards are also being revised accordingly. Among them, Beijing and Tianjin have introduced higher energy-saving requirements, and the energy-saving design standards for residential buildings must reach 75% and public buildings must reach 65%. [0003] Based on the above, it can be seen that the general trend of build...
