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 early strength agent?
What is Early Strength Agent?
Early strength agent is an admixture which accelerates the development of concrete early strength and has no significant effect on later strength.
Under the premise of ensuring the quality of concrete, early strength agent can greatly shorten its final setting time, make it as early as possible, and then accelerate the turnover of template, save template dosage, save energy and save cement, reduce production costs, and improve the output of concrete products.
The cement in the concrete used in construction takes a long time to set and harden before it reaches strength. But in some large engineering concrete precast components or in the cold season construction, often need in a short time to obtain higher strength. Therefore, in the process of concrete mixing, it is common to add early strength agent to achieve the purpose of hardening in a short time.
Early strength agent can greatly improve the strength of cement slurry, mortar and concrete. Adding early strength agent into concrete mixture not only ensures the effect of reducing water, strengthening and compacting of concrete, but also gives full play to the advantage of early strength agent. Adding early strength agent into concrete can ensure the quality of concrete and improve the progress of the project, greatly simplify and reduce the requirements for curing conditions.
1. Make concrete in a short time to achieve higher strength, to meet the requirements of bearing external forces.
2. When the temperature is low, the hardening strength of mortar is slower, especially in some frozen soil, the lower the strength of mortar is more harmful to mortar, if mortar is damaged by freezing will cause permanent damage to mortar, so early strength agent must be added at lower temperature.
Difference between Early Strength Agents and Early Strength Water Reducing Agents:
Early strength agents added to concrete can harden cement in a short time, especially in low-temperature environments, the role of this product is more obvious. The role of early strength water reducing agent is to reduce water in concrete.
