Embodiment Construction
[0019] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail through the following examples, but the present invention is not limited thereto.
[0020] A manufacturing process of green environmental protection bricks for construction, the green environmental protection bricks for construction include materials and water, the ratio of the materials to water is 1:0.463, and the materials are configured by the following proportions by weight Raw material composition:
[0021] Tailings sand 500Kg oyster shell powder 100Kg lime 43Kg cement 42Kg gypsum 27Kg pure aluminum powder 1Kg;
[0022] The production process of the environmental protection brick is as follows:
[0023] (1) Put the tailings sand and oyster shell powder into the corresponding feeding equipment by the forklift according to the proportion of the process requirements. After feeding and mixing, the tailings sand and oyster shell powder enter ...

The invention discloses a green environmental protection brick for building which uses calcined oyster shell powder to replace part of expensive building material raw materials such as lime and cement, and a new process production mode for realizing the preparation of the green environmental protection brick for building. While ensuring the requirements of various technical parameters such as product compressive strength and dry density, the amount of cement and lime added is reduced, and the production cost is reduced. Because oyster shell powder and tailings sand are mixed and ground, a mortar with better performance can be produced. , so that the fineness required by the tailings sand pre-processing process increases from 30% to 60% of the original 0.08mm screen allowance, which reduces the processing time and power consumption of tailings sand, and saves energy; and effectively The utilization and proper disposal of oyster shells produced by coastal oyster farming improves the environment.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a manufacturing process of green environmental protection bricks for building. Background technique [0002] At present, the production process of environmentally friendly bricks has become more and more mature. Most of them use tailings sand, lime, gypsum, cement and other additives as the main raw materials, add water for mixing, and then put the mixed materials into the brick mold. The constant temperature room is left to stand for a period of time, and then the materials after standing are subjected to high temperature and high pressure autoclaving to make environmentally friendly bricks with the characteristics of heat preservation, fire prevention and light weight. According to the traditional formula for the production of environmentally friendly bricks, in order to ensure the stability of production and the technical parameters of the product such as compressiv...
