Summarize the three major characteristics of early strength water reducing agent
Common descriptions of the performance of early-strength water-reducing agents are: high water-reducing rate, very good adaptability to cement, good concrete workability, and no slump in one hour. los…
The dosage and main uses of early strength water reducing agent in concrete
Main properties and parameters of early strength water reducing agent: 1. The dosage is 0.5% ~ 1% of the cement weight, and the water reduction rate can reach 12% ~ 25%; 2. The early strength increase…
How to correctly add water reducing agent and coagulant to mixed concrete
I plan to do an experiment on fast-hardening concrete. If I add water-reducing agent and retardant, how should I add them? I looked up the literature and it said that they should be mixed with water. …
Is there an explanation of the terms for concrete admixtures such as coagulant, early strength agent, reducing agent, and modified air-entraining agent?
Classification of concrete water-reducing agents. Concrete admixtures can be divided into four categories according to their main functions: 1. Admixtures to improve the rheological properties of conc…
There are so many concrete admixtures, such as retarder and reducing agent, what are their functions?
1. The working principle of concrete water-reducing agent: Water-reducing agent is usually a surfactant, which is an anionic surfactant. It is adsorbed on the surface of cement particles so that the p…
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…
What is the working principle of concrete water reducing agent?
Polycarboxylic acid-based inorganic materials are currently attracting widespread attention. They are mainly used in industries such as concrete water-reducing agents, cleaning preservatives, industri…
Dependence of water reducing effect on water reducing agent dosage
The water-reducing effect is highly dependent on the amount of water-reducing agent The admixture used is composed of concrete, slaked lime and fly ash powder, and the total admixture output is 477kg/…
The best time to add water reducing agent retarder to concrete
When are admixtures such as water-reducing agent, retardant and additives added to concrete? ? What role does water reducing agent play in concrete? You will also know when it was added. Answer: Addin…
The role of retarder in water reducing agent
Glucose, also known as corn glucose, corn sugar, or even commonly known as glucose, is a monosaccharide that is widely distributed in nature and is more important. This is A polyhydroxyaldehyde. Pure …
