Abstract
The invention belongs to the technical field of building materials, and particularly, relates to a submarine artificial reef prepared from cement, sulphoaluminate cement, a mortar modifier, an anti-dispersion agent, silica fume, fly ash, slag, an aggregate, and mixing water according to a certain proportion. The submarine artificial reef prepared with a modified cement-based cementitious material as a submarine artificial reef base raw material and directly with seawater as the mixing water has good fluidity under water, is not easy to disperse, is fast in coagulation time, has the 1 day compressive strength of about 5-30 MPa, and has the 28 day compressive strength of about 10-70 MPa. The submarine artificial reef prepared by using the cement, the composite aggregate, seawater and the like is especially suitable for reef engineering construction and emergency maintenance being lack of construction sand and fresh water, also having far transportation distance and being away from a mainland coastline. The submarine artificial reef has the advantages of simple preparation method and wide application.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of seabed artificial reef.
Background technology:
18 of party explicitly points out greatly, and building ocean power is national great strategy, and the development of marine economy be unable to do without the construction of oceanographic engineering, particularly away from the offshore engineering on the island of mainland coastline and Hai Jiao.Due to the tide bulge and fall of seawater, island periphery bare rock and submerged reef random is distributed to the life of the navigation of ship and islander, work brings many inconvenience, therefore fast construction and repairing foundation works on island and on Hai Jiao, such as, submerged reef is under water built up bare rock fast and bare rock is built up the development and utilization of the basis engineering construction such as enforcements to quickening depths, ocean islands and reefs be of great practical significance.But material of construction traditional in the market, as: cement, river sand, stone and fresh water etc. are for the island away from mainland coastline, and these raw-material transports, handling, storage and construction etc. will become very difficult.Not only transportation cost is too high, and simultaneously away under the marine environmental conditions of mainland coastline, particularly the work such as raw-material handling and storage is almost difficult to try out, and traditional underwater construction technology is also difficult to the envrionment conditions adapting to islands and reefs.Therefore research and develop a kind of being suitable for and build the engineering materials of seabed artificial reef and easy construction technology fast at off-lying sea islands and reefs or shoreline, to away from the engineering construction on the island of mainland coastline and Hai Jiao, there is very important strategic importance.
Summary of the invention:
The object of the invention is to propose a kind ofly to be applicable to man reef mortar under the high-performance water of seabed fast construction artificial reef, this reef of man under water mortar not only has good anti-dispersive ability under water, time of coagulation is fast simultaneously, the ultimate compression strength of 24 hours can reach 5-30MPa under water, this mortar later strength development rapidly in addition, within 28 days, 10-70MPa can be reached, the mobility excellent due to this mortar and penetrating power, seabed artificial reef formed after curing and existing reef dish have and well engage and viscosifying power, finally can be built into a novel seabed artificial reef dish from seabed primary concreting to sea level.
The reef of the man under water mortar that the present invention proposes, by cement, aluminosulfate cement, mortar modifier, anti-dispersant, silicon ash, flyash, slag, aggregate and mixing water are formed, and the weight percent of each component is:
Its total amount meets 100%.
In the present invention, described cement is silicate cement, ordinary Portland cement, slag cement, one or more compounds in pulverized fuel ash cement or trass cement.
In the present invention, described aluminosulfate cement is one or more compounds in early-strength type aluminosulfate cement or high-strength aluminosulfate cement.
In the present invention, described mortar modifier is vinylformic acid, ethene and polyvinyl chloride copolymer, naphthalene sulfonic salt, polycarboxylate, one or more compounds in melamine polymers.
In the present invention, described anti-dispersant is polyacrylamide.
In the present invention, the ultra-fine SiO of described silicon ash for being formed during smelting duriron ore
2powder.
In the present invention, the industrial residue that described flyash discharges for coal-burning power plant, the one of I level ash or II level ash.
In the present invention, described slag is levigate blast-furnace slag.
In the present invention, described aggregate is extra large sand, river sand, stone, dead karang and rear one or more compounds expanded in the polyphosphazene polymer resin of formation of water suction.
In the present invention, described mixing water is the one of fresh water or natural sea-water.
Preparation method of the present invention can be divided into following 2 kinds:
1. Extemporaneous method: accurately take raw material in proportion, first take cement, aluminosulfate cement; mortar modifier; silicon ash, flyash, slag and aggregate add stirrer; after take seawater; add seawater while stirring, stir 5-10 minute, shut down after 1-3 minute; continue to stir 1-2 minute, obtain desired product.
2. dry-mixed mortar method: accurately take cement in proportion, aluminosulfate cement, mortar modifier, anti-dispersant, silicon ash, flyash, slag and aggregate, add dry-mixed mortar mixer, stir 5-10 minute, obtained dry blend, then carry out quantitative package according to certain specification, packaging should have moistureproof impervious effect.On-the-spot in use; dry-mixed mortar and seawater join in stirrer in proportion; mix after 5-10 minute; shut down 1-3 minute; as the words of recipe requirements; the polyphosphazene polymer resin etc. accurately taken at the scene again after dead karang and water suction joins in stirrer, continues to stir 3-5 minute, obtains desired product.
Manufacturing process of the present invention and construction technology easy, be suitable for large batch of production, transport and store.
The present invention's ultimate compression strength that man reef mortar detects 1 day through relevant department is under water 5-30MPa, and the ultimate compression strength of 28 days is 10-70MPa
The present invention has following advantage:
1, because the reef of man under water mortar of the present invention has good anti-dispersive ability under water, also there is well mobility under water simultaneously, directly can build shaping, formed after curing seabed artificial reef under water to have with existing reef dish and well engage and viscosifying power.
2, because seabed of the present invention artificial reef not only has higher early strength, (within 24 hours, can 5-30MPa be reached), later strength development simultaneously rapidly (within 28 days, can reach 10-70MPa), therefore is used in fast pouring seabed, seabed artificial reef.
3, because the reef of man under water mortar of the present invention is by using the macromolecule copolymer resin after water suction as artificial aggregate, thus to change in conventional concrete material and all use sandstone as the concrete making technology of aggregate, as used this reef of man under water mortar in away from the islands and reefs engineering construction of mainland coastline, not only can save a large amount of sandstone transports, handling and storage expenses, and then reduce the laid down cost of engineering, a kind of construction technology of novel rush construction fast under water can be provided for the islands and reefs engineering construction lacking sandstone again simultaneously.
4, owing to present invention uses flyash and the slag of large dosage, therefore the manufacturing cost of engineering can significantly be reduced.
5, because starting material of the present invention all adopt mass-produced market finished product, so starting material are easy to get, widespread use is applicable to.
