Factors affecting filter glue non-flow time
Influence filtering Factors of the non-flow time of the glue No flow time definition: if it is a cup test, glueAfter the AB materials are mixed, the stirring time starts. The time until the glue stops…
It will still take time for white oil market demand to gradually pick up
Returning from the holiday after the new year, white oil entered the decline mode in February and fell. The amplitude is relatively large, with market prices generally falling from a year ago, ranging…
[Supply of Magnesium Stearate] When using magnesium stearate in tablets, you need to pay attention to the dosage and mixing time.
Magnesium stearate is a loose white powder with a smooth feel. It is insoluble in water, ethanol and ether, but soluble in hot water and ether. It decomposes into stearic acid when exposed to acid. an…
Effect of retarder on concrete setting time Experiment instructions
Industrially: Retarder is a new type of concrete admixture. There are a large number of hydroxyl and carboxyl groups in its molecular structure, which can form stable complexes with free Ca 2+ in the …
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…
Huaiyuan Antifreeze Manufacturer-When is the best time to add concrete antifreeze?
Contents of this article When is it necessary to add antifreeze to concrete applications? At what temperature should antifreeze be added to concrete? In which month should I start using antifreeze whe…
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…
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…
If 100 cubic meters of concrete plus retarder requires a retarding time of 6 hours, how much retarder should be used?
The dosage of retarder should be determined based on experiments. For example: Calculated based on four ten thousandths of the cementitious material, assuming 400*0.0004=0.16kg/m3 Then 100 cubic meter…
Exchange some quick-setting agents and concrete pouring time as well as retarders
Mainly for night construction of building construction I found on the Internet: “Construction units can also use Retarders and accelerators are used to adjust the setting time of concrete to avo…
