Differences between several kinds of Water Reducing Agents

US President recently decided to invoke a Cold War-era defense law to encourage domestic production of minerals needed to make batteries for electric cars.

This order, issued under the Defense Production Act (DPA), is expected to help miners secure government funding for feasibility studies for new projects to refine lithium, nickel, and other metals for electric vehicles, or to increase productivity at existing facilities.

The funds will not be used to dig new mines or buy minerals for government stocks, and the DPA does not allow the mining industry to evade regulatory or licensing standards. It is unclear how much money could be allocated.

Talon Metals Corp said this decision signaled the US would support responsible domestic mining, processing, and recycling of battery materials, and see it as a matter of national importance. The company has a supply agreement with Tesla to supply materials from a Minnesota nickel mine they are developing.

This move could cause volatility in the prices of metals and other commodities like the concrete superplasticizer.

Introduction to Superplasticizer:

Superplasticizer, or high-efficient water reducing agent, has the functions of high efficient water reduction, slow coagulation, slump, and enhancement. It has strong adaptability to cement, less dosage, is easy to use, especially suitable for high-efficient water reduction and slow coagulation requirements of concrete engineering. The water reduction rate is 18% to 25%.

 

Differences between several kinds of Water Reducing Agent

Lignosulfonate

It is a common water-reducing agent made of lignin. Most of its raw materials are extracted from coniferous trees and other species of material. This water reducing agent mixed with mortar can improve the fluidity of mortar, and enhance the solidification force of mortar. Its water reduction rate is about five to ten percent. 

Naphthalene sulfonate water reducing agent

It is a special water reducing agent. It is the product of naphthalene reacting with sulfuric acid and then fusing with formaldehyde. This water-reducing agent presents different colors from light to deep. It has strong water solubility and a good dispersion effect for a series of powdery building materials like cement. Its water reduction rate is about 10 percent higher than lignin.

Polycarboxylate-based high-performance water reducing agent

It is a newly developed kind of reducing water agent using high technology. It is based on polycarboxylate as the main body of a variety of polymer organic compounds, graft copolymerization generated, with strong water reduction performance, is the world's leading technology environmental protection concrete admixture.

Its compatibility with all kinds of cement is good, the slump of concrete keeps the performance good, can prolong the construction time of concrete. It has a high water reduction rate with a low dosage. It can greatly improve the early and late strength of concrete. It has a low content of chloride ions and alkali, which is beneficial to the durability of concrete. It is a green environmental protection product with a pollution-free production process and without formaldehyde. It is suitable for precast and cast-in-place concrete, reinforced concrete, and prestressed concrete for high-speed railway, passenger dedicated lines, industrial and civil buildings, roads, bridges, ports and docks, airports, and other engineering construction. It is especially suitable for construction projects with long construction time and high requirements for concrete slumps, such as nuclear power projects.

Gas supplies have been in short supply because of the conflict between Russia and Ukraine.  Combined with the situation that other renewable sources cannot produce enough electricity, electricity prices have soared in many parts all over the world. For this reason, I assume the supply and prices of the concrete superplasticizer would keep being influenced by the high energy prices.
