Effect of Concrete Components on the Performance of High-efficient Water Reducing Agent

Diamonds are forever, Gold is precious but which is rarer? Gold is a heavy metal formed during the collision of neutron stars and is one of the rarest elements on Earth.During the formation of the earth, heavy elements gradually accumulated towards the core under the influence of the earth's gravitational force. This means that the closer you get to the Earth's crust, the harder it is to find large quantities of gold.The average concentration of gold in Earth's crust is "very, very low" at just 4 parts per billion. Gold concentrations need to be 1,250 times that level to form a market-worthy deposit.
Diamond is a common element - the concrete water reducer is undoubtedly a good investment opportunity.

Concrete is a mixture of a graded aggregate, sand, water, and cement. It is necessary to study the influence of concrete components on the effect of the high-efficient superplasticizer in order to give full play to their due effect.

Graded aggregate and sand in concrete can be collectively referred to as sand and stone, which has almost no effect on the efficient water reducing agent. From the action mechanism of the efficient water reducing agent, it can be known that the efficient water reducing agent mainly acts on cement, and then affects the properties of concrete.  Therefore, it is an important direction to study the influence of cement on the performance of high-efficient superplasticizers.

The research shows that the properties of cement, such as composition, fineness, and particle shape, have a certain influence on the performance of superplasticizers. 

 

Effect of concrete composition on the performance of high-efficient water reducing agent

It is found in the experiment that the plasticizing effect of slag cement is better than that of ordinary cement when the content of the superplasticizer is constant. Slag cement slag existing in the small particles, in the process of mixing, contributes to high-efficient water reducing agents and a good contact with water, cement, compared with the ordinary cement, slag cement in favor of the circulation of the high-efficient water reducing agent and uniform distribution, more conducive to play a role of the corresponding high-efficient water reducing agent, intuitive performance the plasticizing effect of slag cement is better than that of ordinary cement.

 

Effect of cement particle size on the action capacity of superplasticizer

It is found that the particle size of cement has a great influence on the performance of superplasticizer. Under the condition of keeping the other technological conditions and components unchanged, the smaller the particle size of cement, the more efficient water reducing agent can play its performance; On the contrary, the bigger the particle size of cement, the worse the plasticizing effect of the efficient water-reducing agent on cement.  From the microscopic point of view, the smaller the cement particle size, the more cement particles per unit volume, the larger the specific surface area, and the more full contact with the efficient water reducing agent, the more conducive to the performance of the efficient water reducing agent. 

Experimental data show that when the content of superplasticizer is 1%, the fineness of cement is larger, the efficiency of superplasticizer is more fully played, and the fluidity of cement slurry is better. But when the content of superplasticizer is less than 0.3%, the promotion effect of cement fineness on superplasticizer is almost nonexistent.

 

Effect of cement particle shape on the action ability of superplasticizer

Cement particle shape on the performance of high-efficient water reducing agent role ability is, after mixing cement, cement particles of different shapes, the flocculant produced condensed structure size and difficulty level of each are not identical, cement slurry liquidity difference is bigger, the effect of the high-efficient water reducing agent to join the environment is different, the beneficial effects are different, will affect the ability to function.

 

The results show that the effect of the superplasticizer is stronger when the cement particle shape is gravel than when the cement particle shape is pebble. It can be understood that when cement particles are mixed at any time, it is easier to form a flocculation structure. The formation of flocculation structure is more stable and the structure is more continuous, which is conducive to the efficient water reducing agent playing its own effect. And the flocculation structure composed of cement particles in the shape of pebbles is easy to collapse, and the continuity of Xuning structure is not high. Even if the efficient water reducer is not added, part of the free water will be divergent and added to the cement slurry mixing, so that the ability of the efficient water reducer cannot be fully played out.

Southern Copper Corp (SCCO.N) recently said its Peruvian mine remained closed after a six-week standoff with protesters and blamed the Peruvian government for failing to intervene in the safety of its 1,300 workers and their families.  

The company said in a statement that a recent agreement to end protests at the Cuajone mine required the company to withdraw complaints against protest leaders because railways transporting minerals and supplies remained blocked. Production has been suspended since the end of February.  

Peru's Energy Ministry said in a separate statement that it had also reached an agreement with Southern Copper to start talks to find common ground with local communities.  

"If we shut down for a year, the government will stop receiving more than 3.1 billion soles ($830 million) in taxes and royalties, and 8,000 direct and indirect jobs will be lost. This is what we want to avoid, "Southern Copper added in the statement.

Peru has faced a wave of protests from indigenous communities, who accuse mining companies of not providing enough jobs and funding to poor local residents.  

Central bank officials said last week that protests against copper mines such as MMG's Las Bambas and Southern Copper's Cuajone were dragging down the economy.  

Peru is the world's second-largest copper producer and mining is an important source of tax revenue for the country. It is estimated that the supply and prices of the concrete water reducer will be influenced by that.
