Moreover, because seawater contains a large amount of chloride ions, it is forbidden to be used as mixing water for concrete, and for areas lacking fresh water such as coastal cities, the production of concrete consumes a large amount of fresh water resources
[0004] At the same time, as old buildings in disrepair and municipal demolition buildings, it is difficult to effectively deal with the construction waste generated by their demolition. If they are piled up arbitrarily, on the one hand, it will occupy a large amount of space, and on the other hand, it will also deteriorate the soil quality.
The traditional landfill method will cause further pollution to the environmental soil

[0108] 1. Experimental method
[0109] Weigh the dry material components by weight, put them into the mixer and stir for 1-3 minutes, then add water and water reducer and stir for no less than 2 minutes, vibrate and press the obtained materials, and remove the film after molding for natural maintenance , that is, sea sand recycled concrete slope protection bricks. Wherein, the natural curing is to maintain the formed test block in an environment with a temperature of 18-22°C and a relative humidity of more than 95%, and the curing time is 28 days, so that it can be used for road and river slopes. slope protection bricks. The mixing water is seawater that has not been desalinated. The water reducer is added in an amount of 0.01-1 part by weight.
[0110] The specifications and dimensions of the sea sand recycled concrete slope protection bricks are the same as those of ordinary concrete slope protection bricks. The sea sand recycled concrete slope protection brick has vario...

Abstract
The invention belongs to the technical field of civil engineering materials, and particularly relates to a sea sand recycled concrete revetment brick and a making method thereof.The sea sand recycled concrete revetment brick comprises driers, wherein the driers include, by weight, 10-15 parts of water, 50-60 parts of recycled coarse aggregate and 25-40 parts of sea sand.The invention further provides the making method and application of the sea sand recycled concrete revetment brick.By the adoption of the sea sand recycled concrete revetment brick and the making method thereof, natural resources can be effectively and reasonably utilized, and the environment problem caused by piling of construction waste can be effectively solved.The sea sand recycled concrete revetment brick has the advantages of being low in production cost, high in stress performance, capable of meeting the using requirement for bearing capacity, environmentally friendly and high in economical and ecological benefits.
Description
technical field [0001] The invention belongs to the technical field of civil engineering materials, and relates to a slope protection brick and a manufacturing method thereof, in particular to a sea sand recycled concrete slope protection brick and a manufacturing method thereof. Background technique [0002] With the rapid development of my country's construction industry, the consumption of natural sand and gravel is huge, which not only causes excessive exploitation of resources, but also has a negative impact on the local ecological environment. Among them, slope protection bricks, as a solid or hollow masonry block with natural sand and gravel as the main aggregate, have a wide range of applications and are widely used in road and river slope protection, so the consumption of natural sand and gravel is extremely large. [0003] Sea sand is the second largest marine mineral after oil and natural gas. According to rough statistics, my country's shallow sea sand reserves a...
