Industrial Secrets: Concrete Retarder Formula Revealed
Many chemical industry practitioners have worked for several years without knowing what the concrete retarder formula is. According to senior personnel, the retarder forms an unstable complex between …
What effect does retarder have on the initial setting time of concrete?
As we all know: Coagulant is a new type of coagulation material. It has a saturation point. It will increase beyond that saturation point but not too obviously. You can make a sample to find the optim…
What are the functions of retarder? Can directly replace sodium gluconate
With the development of the concrete industry, the use of various raw materials, cement and other mixed products in different parts of the construction, structural components, and construction methods…
What are the functions of retarder? Can directly replace sodium gluconate
With the development of the concrete industry, the use of various raw materials , cement and other mixed products have increasingly higher requirements for different parts, structural components and c…
Tell you the commonly used testing methods for the retarding time of concrete retarder
In fact, the current evaluation method for the retarding effect of concrete retarder is still relatively limited, mainly the measurement of retarder setting time and setting time difference. 1. For cl…
There are many kinds of concrete retarder formulas, one of which is for reference only
Does the retarder formula have fixed raw materials? Or is it formulated on a case-by-case basis? I don’t know anything about this, so I’d like some advice. Retarders are mainly weak acids …
What is the principle of concrete retarder? Is there any relationship between retarding time and temperature?
Retarder, Retarder, is an admixture that delays the setting time of concrete without significantly affecting the later strength. The main ingredients are polyhydroxy compounds, hydroxycarboxylates and…
Aren’t concrete retarder and gypsum retarder a kind of retarder?
The last process of cement production is to grind the cement materials and gypsum together, in which gypsum (calcium aluminate dihydrate) is generally added About 5% (equivalent to 1~3% SO3), which ac…
It is enough to add retarder admixture directly to concrete. Do you have any ideas?
(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…
