Cement grinding aid is a kind of chemical additives can improve cement grinding effect and performance, can significantly improve the cement production, every period cement strength, were to improve its liquidity.Cement grinding aid can greatly reduce the grinding ball phenomenon formed in the process of electrostatic adsorption package, and can reduce the grinding of ultrafine particles in the process of coalescence trend again.Cement grinding aid can significantly improve the liquidity of cement and improve the mill grinding effect and efficiency of classifier choose powder, so as to reduce the energy consumption of grinding.Using grinding agent in the production of cement with a low compaction trend of coalescence, which benefits the loading and unloading of cement, and can reduce the phenomenon of wall hanging cement silo.As a kind of chemical additives, grinding agent can improve the cement particle distribution and hydration, so as to improve the early strength cement and later strength.

Two ways to reduce energy consumption In 2009, China’s energy consumption was approximately 3.1 billion tons of standard coal, which is expected to reach 3.3 billion tons of standard coal this year, and electricity consumption has increased by more than 20% in the first three months of this year. "Civil and transportation energy demand will continue to increase substantially, and energy consumption will continue to grow. According to the current development situation, we expect energy consumption to reach 4.8 billion tons of standard coal in 2020 and carbon emissions will reach more than 10 billion tons." The six-day forum on oil and chemical energy conservation said.
Dai Yande said that there are two ways to achieve the goal of saving energy and reducing consumption. First, reduce 600 million tons on the basis of the current energy consumption of 3 billion tons of standard coal. Second, we have direct or indirect energy consumption of 600 million tons of standard coal. Exports should reduce this part of energy consumption.
To reduce 600 million tons on the basis of 3 billion tons, it is imperative to put the treasure in energy saving. Dai Yande said that more than 50% of energy saving is from technological progress, and the 12th Five-Year Plan will put energy conservation as a special plan, which has the potential to save energy. With the improvement of energy prices and technological progress, it will continue to increase.
On the other hand, reducing the direct and indirect exports of high-energy-consuming products requires changing the mode of economic growth. However, he also pointed out that the 600 million tons of energy exports are distributed in various areas of production and cannot achieve the goal in one go. The country has introduced a series of taxes and management measures to curb the export of high-energy-consuming products in the past two years, but the economic crisis has come. The pressure to maintain growth has brought this issue back.
Formulating a Climate Change Assessment System Xu Huaqing, director of the Energy Environment and Climate Change Research Center of the Energy Development Institute of the National Development and Reform Commission, said that there are relevant policies in China, including policies and measures such as industry, finance, taxation, technology, and markets. If we want to achieve a 40%-45% emission reduction target and at the same time ensure an 8% GDP growth, fossil energy emissions will reach 9.7 billion tons by 2020, equivalent to the EU-27 plus the United States.
He pointed out that special indicators and assessment systems for dealing with climate change should be developed and pilots of relevant economic instruments such as carbon tax and carbon trading should be carried out. On February 24, the executive meeting of the State Council proposed to establish a carbon emission assessment index system for the steel industry and start the construction of low carbon technology demonstration projects in the petrochemical industry.
According to the report released by the China Chemical Industry Energy-saving Technology Association, the national terminal energy consumption of the petroleum and chemical industry in 2009 was 471.925 million tons of standard coal, which accounted for 15.2% of the country's total energy consumption and accounted for 22.6% of industrial energy consumption.
Dai Yande, deputy director of the Energy Research Institute of the National Development and Reform Commission, said at the 6th China Petroleum and Chemical Energy Forum that for many experts in the 12th Five-Year Plan, 20% of energy-saving targets are proposed. At present, no agreement has been reached, but certainly not less than 15%. The difficulty of the problem lies in how to decompose the indicators. The government should play a leading role in decomposing and implementing energy-saving indicators and link it with local assessments to promote the realization of this goal. Another expert pointed out that special indicators and assessment systems for dealing with climate change should be developed and pilots of relevant economic instruments such as carbon tax and carbon trading should be carried out.
