Traditional portland cement concrete material plays an important role in national economy, and it also will be in new century work
Critical role is occupied in journey Facilities Construction.And portland cement concrete material consumes substantial amounts of Calx in production and preparation process
The mineral resources such as stone, coal and electric power and the energy, discharge a large amount of CO2And SO2, produce greenhouse effect and Acid Rain Pollution etc., with ecology
The arrival in civilization, development green concrete has become inevitable choice.
Maritime concrete refers to use by the sea, in the environment that affected in sea water or by Caulis Piperis Kadsurae, is invaded and harassed by sea water or Caulis Piperis Kadsurae
Concrete.With the enforcement accelerated with every major construction project of China's reform and opening-up paces, maritime concrete is annual
Demand is close to 2 billion cubic meters.Under marine environment, the destructive factor of building structure mainly has：Steel bar corrosion effect, carbonization
Effect, corrosion, salt corrosion effect, freeze-thaw cycle effect, alkali, soda acid corrosion function, impact wear and machine
Tool destruction etc..Wherein, topmost Slope protection is steel bar corrosion effect and salt corrosion effect.In sea water and seashore side
Concrete works due to being corroded by Cl- for a long time, the phenomenon of Rust of Rebar in Concrete is very universal, built sea port dock etc.
Engineering majority does not reach the requirement of projected life.According to statistics, the U.S., every year because of Durability of Concrete, loses nearly 10,000,000,000 beautiful
Unit, occurs a steel bar corrosion to destroy in every 4 buildings.China is every year because inside concrete steel bar corrosion leads to structural deterioration
Lose billions of RMB.
At present, the preparation measure of maritime concrete is mainly on the basis of normal concrete, from admixture high-quality active mineral
The comprehensive technical measure such as compound and high-performance water reducing agent is started with, and improves its corrosion-resistant property.Fundamentally do not solve silicon
The defect of acid salt cement concrete erosion resisting difference.Moreover, maritime concrete engineering in most cases remote location, transport is not
Just, it is difficult to during construction obtain the active mixture of high-quality.Give high property plus multigroup in concrete raw material multiformity and proportioning
The aspects such as the materials procurement of energy maritime concrete, quality control, actual preparation and construction all bring difficulty, and ordinary cement
Production, both consumed substantial amounts of resource, the energy, caused substantial amounts of pollution again.
High to the performance requirement of concrete material under the harsh and unforgiving environments of ocean, steady including high intensity, high-durability and high volume
Qualitative, but traditional concrete technology cannot adapt to the requirement of modern marine engineering, new in the urgent need to research and development
High-performance marine engineering construction new material superior in durability, that environment is good.
On October 23rd, 2014, National Development and Reform Committee, the Ministry of Finance, Ministry of Industry and Information dispatch a joint document, and sea water is mixed foster type concrete row
Enter tackling of key scientific and technical problems engineering, support that Reef in Chinese South Sea construction sea water mixes the industrialization of foster type concrete, support that " coral reef, sand gather materials
Sea water is mixed curing concrete and is gathered materials on the spot utilization rate more than 75%, and intensity is not less than 50MPa within 28 days, and tensile splitting strength is more than 5.0
MPa, sea water mixes foster type concrete " Demonstration Application in islands and reefs are built.
