specific Embodiment approach

[0041] [38] Next, the present invention will be described in detail with reference to examples.

[0042] [39] Examples

[0043] [40] The first process (treatment of primary processing water purification sludge)

[0044] [41] put 1 ton of sludge produced in a sewage purification plant in a rotary kiln and fired it at 800°C-850°C for 3-5 hours in order to completely remove water and organic matter in the sludge to produce 80- 500 kg of primary processing water purification sludge.

[0045] [42] The second process (preparation of green body)

[0046] [43] 22 kg of primary processing water purification sludge, 18 kg of clay, 36 kg of gypsum powder, 14 kg of wax stone and 10 kg of dolomite were mixed, then ground by a ball mill and passed through a 200-mesh sieve to produce a residual amount Less than 1% green body.

[0047] [44] The third process (manufacturing building materials)

[0048] [45] Mix 31.5 kg of green body prepared in the second process above, 2.3 kg of calcined...

Abstract

The present invention discloses a manufacturing method of construction materials using waterworks sludge. The present invention discloses a soundproof construction composition using waterworks sludge and a method for preparing the same. The soundproof construction composition using waterworks sludge manufactured by mixing 22% by weight of a first processed clean water sludge made by firing waterworks sludge for 3-5 hours at 800 DEG C-850 DEG C, with 18% by weight of clay, 36% by weight of terra alba, 14% by weight of agalmatolite, and 10% by weight of dolomite to obtain a body; mixing 31.5% by weight of the body with 2.3% by weight of calcined gypsum, 11.3% by weight of cement, 0.05% by weight of aluminum powder, 0.5% by weight of starch, 0.5% by weight of titanium dioxide to prepare a powdery mixture; and mixing the powdery mixture with 10.8% by weight of phosphoric acid and 43.05% by weight of water.

Description

technical field [0001] [01] The present invention relates to a soundproof building material using sludge from a sewage treatment plant and a method for preparing the same. More specifically, the invention relates to chemical foaming using sewage treatment plant sludge, firstly burning the sewage treatment plant sludge at 800°C to obtain the first processed material, and then generating hydrogen by reacting aluminum powder with acid or alkali A sound-insulating building material in which a plurality of holes is formed in a green body prepared by using a first processed material and a production method thereof. Background technique [0002] [02] Products that have many pores naturally or artificially formed in their ceramic materials have long been processed for thermal insulation, light weight, sound insulation, thermal insulation and filtration purposes. [0003] [03] Representative examples thereof include insulating bricks, lightweight concrete products, porous glass, and...
