Embodiment 1
[0015] The invention provides a method for preparing porous non-fired products from solid waste, which comprises the following steps: using cement, waste and old broken glass powder, gypsum, quartz sand, modified plant fiber (such as plant straw), and sodium silicate as raw materials. , water, polypropylene fiber, foaming agent, water reducer, the above raw materials are calculated as 8 parts, 65 parts, 15 parts, 25 parts, 5 parts, 8 parts, 8 parts, 2 parts, 0.1 parts, 0.05 parts by weight The length of the straw is 2-5 mm. After mixing and stirring evenly, it is vibrated and extruded in a mold to make bricks. After steam curing for 48 hours, it is placed outdoors at room temperature for 13 days to obtain a finished product. Wherein, the length of the modified plant fiber is 2-5mm.
[0016] The modified plant fiber is obtained by modifying the plant fiber through the following steps: firstly, the plant fiber such as plant straw is crushed into a diameter of 3-6 mm, and then pl...
Embodiment 2
[0019] A method and product for preparing porous non-fired products by using solid waste provided in this embodiment are basically the same as in Example 1, except that:
[0020] A method for preparing porous non-fired products from solid waste, characterized in that: cement, waste cullet, gypsum, quartz sand, straw, sodium silicate, water, polypropylene fiber, foaming agent, water reducing agent, the above-mentioned raw materials are 10 parts, 50 parts, 10 parts, 20 parts, 8 parts, 6 parts, 7 parts, 2 parts, 0.1 parts, 0.05 parts by weight, and the length of the straw is 2-5mm. Mix and stir evenly, and then vibrate and extrude in the mold to make adobes. After steam curing for 48 hours, place them outdoors at room temperature for 13 days to obtain finished products.
[0021] Utilize the following steps to modify the stalks, first crushing the plant fibers into a diameter of 3-6mm, and then placing it in (by weight percentage) 5-10% nano silicon dioxide, 5-10% nano calcium car...
Embodiment 3
[0023] A method and product for preparing porous non-fired products by using solid waste provided in this embodiment are basically the same as those in Embodiments 1 and 2, except that:
[0024] A method for preparing porous unfired products by using waste ceramics, characterized in that: cement, waste ceramics, gypsum, quartz sand, straw, sodium silicate, water, polypropylene fiber, foaming agent, and water reducer are used as raw materials. The raw materials are 8 parts, 65 parts, 15 parts, 25 parts, 5 parts, 8 parts, 8 parts, 2 parts, 0.1 parts, 0.05 parts by weight, and the length of the straw is 2-5 mm, which is uniformly mixed , and then vibrated and extruded in the mold to make adobes. After 48 hours of steam curing, they were placed outdoors at room temperature for 14 days to obtain finished products.
[0025] Utilize the following steps to modify the stalks, first crushing the plant fibers into a diameter of 3-6mm, and then placing it in (by weight percentage) 5-10% n...
