Instructions for Use of Water Reducer

A recent poll in Britain found that public support for sanctions against Russia is falling as fuel and prices rise.  

The proportion of people willing to accept higher fuel prices as a result of western sanctions against Russia fell 14 percentage points to 36% from 50% in March, according to a survey conducted for the Telegraph by consultancy Redfield & Wilton Strategies.  

Global energy and fuel prices have soared since the start of the year and remain high because of the conflict between Russia and Ukraine and uncertainty over Russian supplies.  

The survey also found that 54% of people believe their own financial situation has worsened in the past year, up 12 percentage points from 42% two months ago. Sixty-two percent think things will get worse in the year ahead. Less than a third of respondents said they had received a pay rise to keep up with inflation, with two-thirds of those saying it was not enough to keep up with rising living costs.  

The figures suggest that public concern about the conflict with Ukraine is now likely to be overtaken by financial worries.  

Separately, the UK's consumer price index rose 7 percent this month from a year earlier, the highest since March 1992, according to figures released recently by the Office for National Statistics. In addition, a separate report released a few days ago by the Centre for Economics and Business Research said that real household disposable income in the UK will fall by 3% in 2022, equivalent to a loss of £2,320 per household, which would lead to the biggest drop in living standards since the 1950s. That is mainly because wages aren't keeping up with rising energy and fuel costs.  

The prices of other commodities like the concrete water reducer are also expected to be influenced.

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.

Important discoveries have been made in the study of anticancer drugs inhibiting the growth of gastric cancer cells in my country. According to "Science and Technology Daily", a research report provided by Ai Jun and others from the Fourth Hospital of Hebei Medical University showed that seven anticancer drugs including cisplatin had obvious inhibitory effects on gastric cancer cells (BGC-823) in vitro. However, there are certain differences, and it is ideal to use a medium concentration for 48 hours.
The nano-gold provided by our company can be used in various medical technologies such as flow cytometry, immunochromatography, etc. Nano-silver has strong inhibition and Killing effects without developing drug resistance. We also provide concrete water reducer. For more information on concrete water reducer, please consult us.
