Problems solved by technology

[0002] With the rapid growth of economic construction, environmental protection and sustainable development are further deteriorating, and environmental protection requirements are increasing day by day. This is a prominent phenomenon in the field of building materials. First, a large amount of urban construction waste is piled up to form new urban pollution; second, solid clay sintering Bricks destroy cultivated land and consume a lot of energy. Although new wall materials emerge in an endless stream on the market, such as clay hollow bricks, ceramsite hollow blocks, concrete hollow blocks, autoclaved aerated concrete blocks and various wall panels, etc., However, in terms of load-bearing wall materials, there is no suitable material to replace solid clay fired bricks, and there are still defects: when solidified silt or powder containing finer particles, the strength is not significantly improved; ash or fly ash bricks are both A large amount of sand needs to be added, which obviously increases the cost. In terms of wall materials, there are still problems of strength and durability.

Embodiment 1

[0009] 1. Weigh each material in proportion: 10 parts by weight of curing agent, 90 parts by weight of Shifenshan sandy soil, and 10 parts by weight of water; 2. Stirring: Add curing agent and dry mix for 2 to 3 minutes in the Shifenshan sandy soil, then Add water for wet mixing for 2 to 3 minutes, and input the brick machine mold after discharge. 3. Vibration molding: Vibration and pressure for 5 to 20 seconds, the surface of the formed brick should be slightly bleed; 4. Demoulding; 5. Quality inspection; 6. Maintenance: when the ambient temperature is ≥20°C, keep it moist for 14 days; when the ambient temperature is less than 20°C, keep it moisturized for 7 days; when the humidity is less than 75% in natural conservation, sprinkle water on the surface of the brick pile for maintenance, and sprinkle water in the morning, middle and evening 1 time, get the finished product.

Embodiment 2

[0011] 1. Weigh each material in proportion: 8 parts by weight of curing agent, 92 parts by weight of Shifenshan sandy soil, and 10 parts by weight of water; 2. Stirring: add curing agent to dry mix for 2 to 3 minutes in the Shifenshan sandy soil, then Add water for wet mixing for 2 to 3 minutes, and input the brick machine mold after discharge. 3. Vibration molding: Vibration and pressure for 5 to 20 seconds, the surface of the formed brick should be slightly bleed; 4. Demoulding; 5. Quality inspection; 6. Maintenance: when the ambient temperature is ≥20°C, keep it moist for 14 days; when the ambient temperature is less than 20°C, keep it moisturized for 7 days; when the humidity is less than 75% in natural conservation, sprinkle water on the surface of the brick pile for maintenance, and sprinkle water in the morning, middle and evening 1 time, get the finished product.

Abstract

The invention relates to the field of building materials, in particular to a limestone mountain sand baking-free building block which is formed by mixing and compacting 8-15 parts by weight of solidifying agents, 85-92 parts by weight of limestone mountain sand and 10-12 parts by weight of water. Because the building block is made of limestone mountain sand and building garbage, the performance of the building block can meet the requirements of a product specification, the production process of the building block is simple and is easy to operate, and the cost of the building block is 30% lower than that of limesand bricks and concrete bricks; and waste limestone mountain sand and building garbage are changed into valuables.
