Global water reducer market trend 2022-2028 Mechanism of Water Reducer by Newspfcstal

Recently, the world's largest investment management corporation, BlackRock, in a market research report said that currently, they prefer U.S. and Japanese equities to European equities because of the energy problem stemming from Russia's invasion of Ukraine.

"Russia's invasion of Ukraine caused terrible injuries, a surge in commodity prices, and food and energy security issues," BlackRock, "It is stifling the economic growth and fulling inflation driven by supply problems. Europe is most affected among those developed markets, as it is trying to wean itself off Russian energy."

The volatile international political situations will continue to affect the markets and prices of many commodities like the water reducer.

Introduction to Water Reducer

The water-reducing agent or concrete water reducer is a kind of concrete admixture that can reduce the water consumption under the condition of keeping the slump of concrete basically unchanged. It has a dispersive effect on cement particles, can improve its workability, reduce water consumption per unit, improve the fluidity of concrete mixture, or reduce the amount of cement per unit, saving cement.

 

Applications of Water Reducer

The water reducing agent is suitable for all kinds of industrial and civil construction, water conservancy, transportation, port, municipal engineering precast, and casting reinforced concrete;

Suitable for high strength, ultra-high-strength, and medium strength concrete, as well as the requirements of early strength, moderate frost resistance, and large mobility concrete;

Suitable for steam curing precast concrete components;

Suitable for water reduction and enhancement components of various compound admixtures (master material).

 

Mechanism of Water Reducer

1.Dispersion: After mixing with water, due to the hydration of cement particles, cement particles’ surface forms a double electric layer, which forms a solvation water film. And the cement particle surface with opposite charges makes cement particles between associating with cooperation, to form a slurry flocculation structure, making that the 10% ~ 30% of the mixing water is wrapped in cement particles, so that they cannot participate in free flow and lubrication, affecting the fluidity of concrete mixture. When adding water reducing agent, because the water reducing agent molecules adsorbed on the surface of cement particles can redirect, cement particle surface (usually a negative charge) with the same charge, form the electrostatic repulsion, prompting the cement particles to disperse mutually, flocculation structure collapse, release the wrapped part of the water, participate in the flow, so as to effectively increase the liquidity of concrete mixture.

2.Lubrication: Water-reducing agent in the hydrophilic base polarity is very strong, so the cement particle surface of the water-reducing agent adsorption film and water molecules can form a stable layer of solvated water film, this layer of water film has good lubrication, can effectively reduce the sliding resistance between cement particles, so that the fluidity of concrete is further improved.

3.Steric resistance: The hydrophilic branch chain in the structure of the water reducing agent is extended in an aqueous solution, so as to form a hydrophilic three-dimensional adsorption layer with a certain thickness on the surface of the adsorbed cement particles.  When the cement particles close, the adsorption layer began to overlap, that is, the cement particles produce space resistance, the more overlap, and space resistance repulsion, the greater the condensation of cement particles hinder the greater, so that the slump of concrete to maintain good.

4.Sustained release effect of graft copolymerization branch chain: New type of water-reducing agent such as poly (carboxylic acid water-reducing agent in the process of preparation, the molecules of water-reducing agent on the grafting on some of the branched-chain, the branched-chain not only can provide space steric effect, and, in the high basicity of cement hydration environment, the branched-chain can also slowly is cut off, to release more carboxylic acid with dispersion effect, so that it can improve the effectiveness of the dispersion of cement particles, and control the slump loss.

The development of the Russia-Ukraine conflict will continue to dominate the commodity prices such as the water reducer in the future. If the conflict eases or cools, Russia and Ukraine go back to negotiate, commodity prices would fall. However, if the situation between Russia and Ukraine deteriorates further, or evolves into a full-scale war, the price of the water reducer is predicted to see further improvement over the coming days.
