Gold is a high-quality hedge hedging tool, favored by investors. Especially in recent years, with the increasing instability of the world economy, gold has become one of the preferred asset allocations of investors because of its functions of hedging and fighting inflation. 

Earlier, the worsening situation in Ukraine sent gold prices soaring to a two-year high of $2,070 an ounce. But gold, along with other commodities, fell back last week as conditions changed and bulls took profits, hitting a low of $1,895 an ounce. Rising gold prices may also have an impact on the early strength agent,superplasticizer for concrete prices. 

According to China Business News, Goldman Sachs raised its gold price forecast in early March, considering Asian buyers' gold consumption demand, investment demand and central bank gold purchase demand continue to rise. Three -, six - and 12-month targets were raised to $2,300, $2,500 and $2,500 an ounce, respectively, from $1,950, $2,050 and $2,150. The last time all three accelerated was in 2010-11 when gold prices rose nearly 70%. 

The World Gold Council has also noted that global gold demand is at its highest level in nearly two years, which is linked to a recovery in consumption and consumer sentiment to combat inflation. 

1 Definition

Early strength admixture refers to the admixture that can improve the early strength of concrete and has no significant effect on the later strength.

Superplasticizer for concrete is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete basically unchanged.

2 Categories

Early-strength agents can be divided into three categories according to chemical composition: strong electrolyte inorganic salts, water-soluble organic compounds, and composite early-strength agents composed of organic and inorganic compounds.

Polycarboxylic superplasticizers are usually divided into: lignosulfonate superplasticizers, naphthalene superplasticizers, melamine superplasticizers, sulfamate superplasticizers, and fatty acid superplasticizers according to their chemical composition. Superplasticizers, polycarboxylate superplasticizers.

3 Main ingredients

In addition to chloride and sulfate, early strength agents include nitrite, chromate, etc., as well as organic substances such as triethanolamine, calcium formate, urea, etc.

Different types of superplasticizer for concrete have very different components. It is mainly a surfactant. Currently, the third-generation polycarboxylate superplasticizer is widely used.

4 Uses

The early strength agent does not contain chloride ions and has no rust effect on steel bars. It is suitable for all civil and industrial buildings, prestressed reinforced concrete components, mortar, etc. It is most suitable for construction under low temperature conditions in early winter and early spring. .

Water reducing agent is widely used in high-speed rail, high-speed, civil, industrial buildings and prefabricated component factories, etc. It has wide applicability and is suitable for all seasons.

5 Notes

The dosage of early strength agent is 3-6% of cement. In order to keep the quality of the concrete mixed with this agent uniform, the stirring time is prolonged by 1-2 minutes. Concrete mixed with early strength agent cannot use active mineral orthopedics (such as opal). If this agent is damp and agglomerated, it must be crushed or weathered before use, and its performance remains unchanged.

Because there are many types of superplasticizers, the appropriate type of superplasticizer should be selected according to the needs of the project. For winter construction, it is recommended to use the third-generation polycarboxylate superplasticizer.

Affected by the present complex international situation and the epidemic, the future of global financial markets, futures markets, and stock markets is still highly uncertain. For this reason, I suppose the price of the early strength agent,superplasticizer for concrete would continue to rise.
