Global concrete water reducer market trend 2023-2028 Instructions for Use of Water Reducer by Newspingsnyc

The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring:  Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the concrete water reducer? 

Where Can the Water Reducer be Applied?

The concrete water reducer is suitable for the pumping or normal concrete engineering with a strength grade of C15 to C60 or above. It is especially suitable for concrete projects with high durability, high flow state, high slump protection, high strength, and high appearance quality requirements. It is very beneficial to the preparation of high fluidity concrete, self-compacting concrete, and plain-faced concrete. 

Ordinary water-reducing agents should be used for daily minimum temperature above 5 construction of concrete. High efficient water-reducing agents are suitable for daily minimum temperature above 0 construction of concrete, and suitable for the preparation of large fluidity concrete, high strength concrete, and steam curing concrete. 

 

How to Use the Water Reducer?

Polycarboxylate High-performance Water Reducer:

1, The dosage is 0.5%~2.0% of the total weight of the cementitious material, and the commonly used dosage is 0.2% ~ 0.5%. The concrete test should be carried out before use in order to optimize the dosage;

2, It cannot be used with the naphthalene system high-efficient water reducing agent compound, and other admixtures should also be used in advance of concrete compatibility experiment; 

3, Water consumption must be strictly controlled when using, because it affects slump.

4, Pay attention to concrete surface maintenance. 

 

Naphthalene Series High-efficient Water Reducer:

1, Dosage range: powder: 0.75%-1.5%; liquid: 1.5 to 2.5%. 

2, When using porous aggregate water should first be added and stirred, and then water reducer is added.

3, When the slump is large, the vibration time should not be too long, so that bleeding and stratification could be prevented.

 

HSB Aliphatic Superplasticizer 

1. Find out the best dosage through experiments. The recommended dosage is 1.5-2%; 

2, Add HSB and water together into concrete.

3. Due to the high water-reduction rate of HSB, a layer of yellow slurry will be secreted on the surface of the concrete before the initial setting, which is a normal phenomenon.  Finished concrete slurry wipe light, the color will be eliminated, or in concrete strength, the color will naturally eliminate, watering and maintenance color will be eliminated faster. It does not affect the inner and surface performance of concrete. 

 

Suppliers of Concrete Additives

The water reducer with stable quality should be selected. There should be good compatibility between water reducing agent and cement and admixture. When a variety of admixtures with different functions are used in combination, there should be good adaptability between admixtures and between admixtures and cement.

The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.  

The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.  

Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.  

U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.  

The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."  

The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled concrete water reducer are estimated to be influenced by international political situation changes.
