A seawater mixed coral sand artificial aggregate concrete block and its preparation method

Abstract

The invention discloses a seawater coral sand artificial aggregate concrete block and a preparation method thereof. A novel block material adopts a small amount of spherical water-absorbing resin for absorbing seawater to prepare a large amount of artificial aggregates instead of coarse aggregates such as gravel in conventional concrete, island coral sand is utilized for replacing fine aggregates such as river sand in the conventional concrete, natural seawater is adopted for mixing to produce a novel concrete prefabricated block with an inner housing honeycomb structure, and the block is used for a wall masonry structure in island project construction. The block is light in mass, good in thermal performance, simple to produce and convenient to use; the material transport amount of the island project construction is reduced by more than 60%, local material utilization and industrialized production of island project construction materials can be realized, and a novel building masonry material is provided for solving problems of difficult transportation, high cost, long cycle and the like of the island project construction materials.

Description

technical field [0001] The invention belongs to the technical field of new building materials, and in particular relates to an artificial aggregate concrete block of coral sand mixed with seawater and a preparation method thereof. Background technique [0002] my country's South China Sea is rich in mineral resources, and its strategic location is extremely important. Accelerating the construction of islands and reefs in the South China Sea is a prerequisite for effectively exercising sovereignty, guarding the main sea traffic routes, and developing and utilizing marine resources. However, because the islands and reefs in the South China Sea are far away from the inland, the environmental conditions are harsh, and the supply of materials is difficult, so the development of the islands and reefs is very difficult. At present, many islands and reefs have no garrison facilities and are illegally encroached upon by neighboring countries, which seriously restricts the maintenance...

AI Technical Summary

Problems solved by technology

[0003] South China Sea islands and reefs have no directly usable building materials. The sand, stones, blocks and other materials needed for engineering construction need to be raised or prefabricated inland, and then transported to the islands and reefs in the distant sea. The cost is high, and it is often affected by sea conditions and weather. The construction period is delayed; in addition, the islands and reefs have complex topography and narrow sites, and large ships cannot approach them, making it extremely difficult to turn around materials. Therefore, research on the use of rich coral sand and seawater resources on islands and reefs to organize the production of building block materials on the spot will be of great help to speed up the construction of South China Sea islands and reefs. Engineering construction is of great significance
