Abstract

The invention relates to a sludge enhanced baking-free brick and a preparation method thereof. The sludge enhanced baking-free brick comprises the following components by mass ratio: 30-50 parts of sludge powder, 30-50 parts of cement, 0.5 parts of a polymerizer, 3-5 parts of an exciting agent, and 15-20 parts of water. The method uses sludge for substituting a crushed stone aggregate, uniform bearing in the bricks and brick body intensity are increased by the sludge granulation aggregate, a broken stone mineral resource is saved, the land occupation is reduced, the environment is protected, the energy is saved, and the social benefit is increased.

Example Embodiment

[0036] The invention also provides a method for preparing sludge-enhanced non-burning bricks, figure 1 It is the production process flow chart of the sludge-enhanced non-burning brick of the present invention, such as figure 1 As shown, including the following steps:
[0037] S100. Using river sludge and/or sewage sludge or activated sludge as the main raw material, after deodorizing, drying, and pulverizing, it is mixed with cement and polymerizers and then granulated to form stable soil particles;
[0038] S200. Mix the stabilized soil particles, cement and activator uniformly, and press them into a shape;
[0039] S300: Curing for 7 to 14 days under natural conditions to obtain the residual sludge-free brick.
[0040] In another preferred embodiment of the present invention, in the step S100, the water content of the river sludge or sewage sludge is less than 8% after drying and dehydration, and the particle size after crushing is less than 1 mm. The sludge powder is mixed with cement and polymerizing agent and then granulated. After aging for a period of time, stable soil particles of 3-25mm are formed.
[0041] In the preparation method of the sludge-enhanced non-burning brick of the present invention, the quality ratio of each component is as follows:

Example Embodiment

[0044] Example 1
[0045] The sludge-enhanced non-burning brick is made of river sludge, sewage sludge, cement, polymerization agent, activator, granulated, pressurized, and cured. The quality of sludge powder, cement, polymerization agent, activator and water The ratio is 50, 30, 0.5, 3, 15. The preparation process of sludge-enhanced non-burning bricks is as follows figure 1 As shown, (1) river sludge and sewage sludge are deodorized and dehydrated, and then pulverized to obtain river sludge and sewage sludge powder; (2) river sludge, sewage sludge powder and cement, polymerizers, and activators Mix, add appropriate amount of water, fully stir, roll compaction and then granulate; the granulated cement content accounts for 50% of the unit proportion of cement; (3) Then the river sludge and sewage sludge particles are mixed with the remaining cement and activator, and then added Appropriate amount of water, fully agitated, rolled, and then molded and molded at 400KN. After curing and demolding, a non-burning brick with a length and width of 240×115×53mm is made, and the strength of 14d reaches 12MPa.

Example Embodiment

[0046] Example 2
[0047] Sludge-enhanced non-burning bricks are made by mixing river sludge, activated sludge, cement, polymerizing agent, activator, granulating, pressing embryos, and curing. The dry powder of river sludge, activated sludge dry powder, cement, polymerizing agent, activating agent The mass ratio with water is 40, 40, 0.5, 5, 15. The preparation process of sludge-enhanced non-burning bricks is as follows figure 1 As shown, (1) the river sludge and activated sludge are deodorized and then dehydrated, and the river sludge and activated sludge powder are obtained through pulverization; (2) the river sludge, activated sludge powder and cement, polymerization agent, and activator Mix, add appropriate amount of water, fully stir, roll compaction, and then granulate; the amount of granulated cement accounts for 50% of the unit proportion of cement; (3) Mix the river sludge, activated sludge with the remaining cement and activator, and add an appropriate amount Water, fully agitated, rolled, and then molded and molded at 400KN. After curing and demolding, a non-burning brick with a length and width of 240×115×53mm is made, and the strength of 14d reaches 14MPa.
