The effect of Self Curing Compound PEG 400(0% to 2% in steps of 0.5%) on compressive strength of M25 SCC Mix is not investigated as per the literature cited. The present investigation finds the effect of PEG 400 self curing compound on compressive strength of M25 SCC Mix.

IS:10262-2019 mix design is used. The workability properties Slump Flow, satisfy EFNARC Guidelines, but VFunnel does not satisfy EFNARC Guidelines. For PEG 400 0.5% to 1.5% compressive strength obtained is more than the target mean strength. For PEG 400 0.0% to 2.0% compressive strength obtained is more than the characteristic compressive strength. Compressive strength of mix with 0.5% self curing compound is more than 52% compared to mix with 0% self curing compound.

Where,
For achieving the desired quality of SCC, proper curing is essential. But in practice achieving proper curing is difficult due to dependency on human. Also requires water daily during the curing period. Hence researchers are using self curing compound. The effect of PEG 400 Self Curing Compound on compressive strength M25 SCC Mix is not investigated [3][6] as per the literature cited. The present investigation finds the effect of PEG 400 self curing compound on compressive strength of M25 SCC Mix.
s = standard deviation – 4 X = 5.5 Step 2: Approximate Air Content: From IS: 10262 table 3, the approximate amount of entrapped air is 1% for 20 mm nominal size aggregate.
The IS 10262-2019 mix design is used. Master Glenium SKY 8233 super plasticizer is used. Mix grade M25 SCC considered in investigation.
