The formula and production method of water reducer for concrete

The World Bank expects global economic growth to slow significantly, from 5.5% in 2021 to 4.1% in 2022 and further to 3.2% in 2023. Growth in East Asia and the Pacific is expected to slow to 5.1 percent in 2022, reflecting the impact of China's economic slowdown, the report said. China's economic growth is expected to fall to 5.1% in 2022, close to potential growth, due to the ongoing impact of the COVID-19 pandemic and the Chinese government's tightening of regulations in certain sectors of the economy. The report said that the rapid spread of the Omicron variant means that the new crown epidemic is likely to continue to disrupt economic activity in the near future. In addition, decelerating growth in major economies, including the United States and China, will depress external demand in emerging markets and developing economies.
Slow economic growth has a huge impact on water reducer,water reducing agent ,concrete admixtures.

The application of various concrete admixtures can not only improve the performance of concrete, but also promote the development of new concrete technologies, promote the application of industrial by-products in cementitious material systems, and also help save resources and protect the environment. , has gradually become an essential material for high-quality concrete. Among them, the water reducing agent is a kind of concrete, and the water reducing agent is a concrete admixture that can reduce the mixing water consumption under the condition that the concrete slump is basically unchanged. Most of them are anionic surfactants, such as lignosulfonate, naphthalene sulfonate formaldehyde polymer, etc. When we add the concrete mixture, it has a dispersing effect on the cement particles, which can improve its workability, reduce the unit water consumption, and improve the fluidity of the concrete mixture; or reduce the unit cement consumption, effectively saving cement.


The specific operation method of the water reducing agent formula for concrete:

1. Maleic anhydride is prepared into a 5-7% solution according to the required amount and recorded as the head material.

2. The initiator is prepared into a 5-10% solution for later use.

3. Add the required amount of APEG or TPEG, heat to liquefy it, and then add the headstock.

4. Nitrogen replacement;

5. When the temperature rises to 75-85°C, the initiator is added dropwise, and the dropwise addition is completed at 80°C for 1.5-2 hours.

6. After the dropwise addition of the initiator is completed, keep the temperature at 80-90° C. for 4-4.5 hours to complete the reaction and cool down.

7. When the temperature drops to 40-50℃, add 50% KOH solution to neutralize to PH: 7-8.

8. After measuring the solid content, add the measured soft water according to the required solid content.

9. After the solid content is determined to be qualified, discharge the material.


After the above experiments, we can get the basic formula of water reducer for concrete:

Concrete water reducer formula 1:

Hydroxyethyl acrylate: 25g, acrylamide: 5g, allyl polyoxyethylene ether: 175g, sodium persulfate: 10g, neutralized by sodium hydroxide.

Concrete water reducer formula 2:

Allyl polyoxyethylene glycol ether: 40 g, acrylic monomer: 30 g, 10% ammonium persulfate aqueous solution 40 g, neutralized with triethanolamine.

Concrete water reducer formula 3:

Allyl polyoxyethylene glycol ether: 100 g, methacrylic acid: 70 g, acrylic acid: 20 g, 10% aqueous ammonium persulfate solution: 50 g, neutralized with sodium hydroxide.

Concrete water reducer formula 4:

Methacrylic acid: 25g:, allyl polyoxyethylene ether: 175g, sodium persulfate: 10g. , neutralized with sodium hydroxide.

Concrete water reducer formula 5:

TPEG: 180 g, hydrogen peroxide: 0.63 g, thioglycolic acid: 0.56 g, ascorbic acid: 0.3 g, acrylic acid: 182.3 g, neutralized with sodium hydroxide.

Concrete water reducer formula 6:

APEG: 180 g, hydrogen peroxide: 10 g, thioglycolic acid: 2.07 g, itaconic acid: 10 g, methacrylic acid: 21.23 g, neutralized with sodium hydroxide.

The latest poll by CSA for consumer finance company Cofidis shows the French are taking action to trim their budgets as inflation erodes household purchasing power.  

According to Le Figaro, the poll shows that French people think they need to earn an average of 490 euros more a month in order to live a decent life. This is an increase of 23 euros compared to the purchasing power barometer published in September 2021. Amid inflation and international tensions, this average in the polls masks differences among households, with some social groups much more severely affected by the decline in purchasing power than others. Seventy-eight percent of single-parent households, 76 percent of 25-to 34-year-olds, and 72 percent of blue-collar workers said the international situation had had a negative impact on their personal finances, compared with 64 percent of all French people.  

In response to rising prices, soaring energy, and food prices, in particular, the French government is preparing to launch a package of measures designed to increase the purchasing power, such as extending the energy price protection mechanism, the extension of the fuel discount measures, and more targeted alternative measures, will be distributed inflation-linked pension and social security benefits, check the "food" and so on.

Because of the soaring energy prices, the water reducer,water reducing agent ,concrete admixtures price is predicted to rise in the future.
