In simple terms, sugar acts as a retarder and delays the setting time of concrete. ... Sugars have been categorized as 'cement destroyers' and when sugar is added to Portland cement paste at the onset of mixing, hardening may be delayed indefinitely. Concrete hardens due to formation of calcium silicate hydrate.
How much sugar do you add to concrete?
Overall results of this study indicate that, for avoiding adverse effects on setting time and strength, dosage of sugar should be in the range of 0.05–0.1% by weight of both types of cements considered in the present case study.
Can we use sugar in concrete?
In simple terms, sugar acts as a retarder and delays the setting time of concrete. ... Sugars have been categorized as 'cement destroyers' and when sugar is added to Portland cement paste at the onset of mixing, hardening may be delayed indefinitely. Concrete hardens due to formation of calcium silicate hydrate.
Does adding sugar to concrete ruin it?
Sugars have been categorized as 'cement destroyers' and when sugar is added to Portland cement paste at the onset of mixing, hardening may be delayed indefinitely. Concrete hardens due to formation of calcium silicate hydrate. ... Sugar exceeding 0.2% by weight of concrete will slow down the reaction drastically.
What happens if I add sugar to concrete?
In simple terms, sugar acts as a retarder and delays the setting time of concrete. ... Sugars have been categorized as 'cement destroyers' and when sugar is added to Portland cement paste at the onset of mixing, hardening may be delayed indefinitely. Concrete hardens due to formation of calcium silicate hydrate.
Is sugar good for concrete?
In simple terms, sugar acts as a retarder and delays the setting time of concrete. ... The retarding action of sugar is probably by the prevention of the formation of calcium silicate hydrate. Sugar exceeding 0.2% by weight of concrete will slow down the reaction drastically.
How much sugar do you put in exposed concrete?

What is sugar used for in concrete?
Sugar increases the setting time of cement up to 1.33 hrs at dosage level of 0.06% by wt of cement. There will be no effect on workability, compaction by the use of sugar as admixture in concrete. Higher long-term compressive strength is achieved in concrete by the use of sugar as admixture.
Does sugar strengthen concrete?
The sugar slows down the setting of the concrete, and is used in hot conditions or when large amounts of concrete must be poured out before setting occurs. Very small amounts of sugar delays the hardening of concrete without influencing its strength or other properties once finally set.
