Problems solved by technology

Moreover, the local fresh water on the islands and reefs is scarce, and the cost of sea and fresh water is relatively high. As a result, the survival rate of newly planted green plants in the dry season on the South China Sea islands and reefs is reduced, and the growth of planted green plants is declining.

preparation example Construction

[0046] Such as figure 1 Shown, the preparation method of the coral reef ceramsite in the embodiment of the present invention comprises the following steps:

[0047] Step 101, placing preset raw materials in a granulator for powder coating and granulation to obtain coral reef ceramsite.

[0048] Wherein, the preset raw materials include: 10-30mm coral reef, Portland cement, functional additives and seawater;

[0049] The weight ratio of the preset raw materials is: 75-88 parts by weight of 10-30mm coral reef, 7-14 parts by weight of Portland cement, 3-9 parts by weight of functional additives, and 2-6 parts by weight of fresh sea water.

[0050] In the technical scheme of the present invention, the above-mentioned coral reefs can directly use the 10-30mm coral reefs on the islands and reefs of tropical oceans, so materials can be obtained locally, and the loose and porous coral reefs that are naturally screened or mechanically broken can be used as granulated Tao nuclear. Si...

Embodiment 1

[0084] In this embodiment, the preset raw materials include: 10-20 mm coral reef, Portland cement, functional additives and seawater;

[0085] The weight ratio of the preset raw materials is: 82-86 parts by weight of 10-20mm coral reef, 9-12 parts by weight of Portland cement, 2-2.5 parts by weight of functional additives, and 3-5 parts by weight of fresh sea water.

[0086] In addition, preferably, in a specific embodiment of the present invention, the main chemical composition of the 10-20mm coral reef is 95% CaCO 3 , the porosity is 30% to 34%, the saturated water absorption is 14% to 16%, the cylinder compressive strength is 5.8 to 7.0MPa, and the crushing index is 29% to 32%; the openings in the 10 to 20mm coral reef are connected pores The proportion of the pores is greater than 60%, and the diameter of more than 95% of the main pores is greater than 700nm.

[0087] In addition, preferably, in a specific embodiment of the present invention, the local natural water conte...

Embodiment 2

[0099] In this embodiment, the preset raw materials include: 10-30mm coral reef, Portland cement, functional additives and seawater;

[0100] The weight ratio of the preset raw materials is: 83.5 parts by weight of 10-30 mm coral reef, 9 parts by weight of Portland cement, 5.0 parts by weight of functional additives, and 2.5 parts by weight of seawater.

[0101] In addition, preferably, in a specific embodiment of the present invention, the main chemical composition of the 10-30mm coral reef is 95% CaCO 3 , The porosity is 31%, the saturated water absorption is 14.7%, the cylinder compressive strength is 6.5MPa, and the crushing index is 28%.

[0102] In addition, preferably, in a specific embodiment of the present invention, the local natural water content of the 10-30mm coral reefs in the South China Sea is 13%.

[0103] In addition, preferably, in a specific embodiment of the present invention, the functional auxiliary agent includes: ground steel slag powder, emulsified a...

Abstract

The invention provides a preparation method of coral reef ceramsite. The preparation method comprises the following steps: putting pre-set raw materials into a granulating machine and carrying out powder covering and granulation, so as to obtain the coral reef ceramsite; carrying out spreading and airing on the obtained coral reef ceramsite for a pre-set first duration; covering the spread and aired coral reef ceramsite with a layer of covering material, and carrying out wet and hot curing for a pre-set second duration; carrying out open-air natural stacking and curing on the coral reef ceramsite subjected to the wet and hot curing for a pre-set third duration. By adopting the preparation method of the coral reef ceramsite, provided by the invention, energy sources and clay resources can be saved and long-distance transportation cost of a large amount of clay is reduced, so that the prepared coral reef ceramsite has the characteristics of low cost, low energy consumption and greennessand environment friendliness.

Description

technical field [0001] The application relates to the technical fields of marine engineering and new materials, in particular to a preparation method of coral reef ceramsite. Background technique [0002] There are many islands and reefs in the South my country Sea that are more than 1,000 kilometers away from the inland. For example, Meiji Reef is located near 10° north latitude. More than 95% of the islands and reefs in the South China Sea are natural tropical coral reefs, and there are no common sandstones and clays that are common inland on the islands and reefs. Therefore, all kinds of building materials used in the construction of islands and reefs in the South my country Sea are transported by large cargo ships from inland areas such as Hainan, Guangxi, and Guangdong to the islands and reefs after long distances. Therefore, the comprehensive cost of sea transportation during the construction of the South China Sea is relatively high, and the transportation cost of sa...
