Concrete is often used in cement pavement or house construction, and some admixtures are added. So, what are the functions of concrete early strength additives? Come take a look now.
1. The role of concrete early strength agent
Helps cement to harden quickly at low temperature and makes concrete Reach strength quickly
1. When the temperature is low, the hardening strength of mortar is slower, especially in some frozen soil areas. The lower the strength, the more harmful it will be to the mortar. If the mortar is damaged by freezing, it will cause permanent damage to the mortar, so early strength additives must be added at lower temperatures.
2. Make concrete reach higher strength in a short time to meet the requirements of withstanding external forces.
1. Adding early strength agent can make the cement harden quickly under low temperature conditions, greatly shorten the final setting time of concrete, and make it demould as soon as possible, while ensuring Under the premise of improving the quality of concrete, the strength of cement slurry, mortar and concrete can be greatly improved, production costs can be reduced, and the output of concrete products can be increased, especially during winter construction or in urgent maintenance projects.
2. Incorporating early-strength additives can also enhance the effects of water reduction, reinforcement, and compaction of concrete, giving full play to the characteristics of early-strength additives.
2. Application scope of concrete early strength agent
1. Below -5 When constructing in a low temperature environment of ℃, it is necessary to add early strength agent to accelerate the condensation and hardening degree. Otherwise, the cement concrete at low temperature will cause freezing damage, accelerate the turnover of the formwork, and improve the construction efficiency.
2. Fast cement concrete pavement, especially at level crossings. When paving cement concrete pavement in one direction, the manufacturing difficulty and cost also increase. Early-strength cement concrete can be used for construction, which can facilitate vehicle traffic in a short period of time.
3. It can be used for rapid repair of cement concrete pavements and bridges, opening up traffic as soon as possible, and improving traffic efficiency.
Conclusion of the article: This is the introduction to the role of concrete early strength agent. I hope it will be helpful to everyone. </p
