How to make concrete rust inhibitor Zhejiang rust inhibitor manufacturer Shanghai’s best rust inhibitor
Coastal ports, salt fields and saline soil areas usually contain large amounts of sulfate and chloride salts, which have a serious corrosive effect on concrete and steel bars, causing the reinforced c…
More than 50% concrete friends must know the definition of concrete segregation and bleeding. Shanxi anti-segregation agent manufacturer Hebei concrete segregation agent
1. Definition of concrete segregation: Concrete segregation is the separation between the components of the concrete mixture. The cohesion is insufficient to resist the sinking of coarse aggregate, ca…
Comprehensive explanation of concrete segregation Heilongjiang anti-segregation agent manufacturer Liaoning concrete anti-segregation agent
Concrete bleeding and segregation often occur in concrete projects, causing serious impact on the strength, durability and construction quality of concrete. Bleeding refers to the phenomenon of concre…
What precautions should be taken when adding coagulant during concrete pumping?
(1) Pay attention to the mutual adaptation with the cementitious material system. For different cementitious material systems, they can show different condensation and hardening properties, and they a…
The correct way to use lubricating agent Hebei lubricating agent manufacturer Liaoning concrete pump truck lubricating agent price
The emergence of pump truck lubricating agent has replaced the role of traditional cement mortar in lubricating pump truck pipe walls. Lubricant lubricating pump pipes mainly have the following charac…
What is the purpose of adding retarder and water reducing agent to pumped concrete?
1. Retarder: Pumped concrete mostly uses commercial concrete, which requires small slump loss. Especially for large-volume concrete or concrete constructed at high temperatures in summer, retarder mus…
Are concrete retarder and early strength agent mutually exclusive? Why should they be used?
Concrete retarder delays the initial setting time of concrete, that is, it inhibits the hydration rate of cement. Early strength additives increase the hydration rate and facilitate the early improvem…
Why is retardant added to concrete for construction projects?
Retarding water-reducing admixtures mainly affect the properties of fresh concrete and hard-base concrete. The hazards to the properties of freshly mixed soil are roughly as follows: (1 ) Increase the…
What is the main impact of retarder on the performance of concrete?
1. Retarder is a common water-reducing agent used to increase the initial setting time of concrete. At the construction site in summer, proper addition of retarder can make the new Mixed soil maintain…
Why are concrete retarder and early strength agent suitable for construction in high temperature and low temperature environments respectively?
Retarder for concrete is mainly used at high temperatures, because the concrete is made by pouring and smoothing, which requires a certain amount of time, and because of the high temperature environme…
