the effect is but not so appreciable ultimately durability of concrete is reduced
NO there is not and my experience in using the curing compound in hot weather concreting is even seeing some cracks on top surface and ive never seen any more strength that way but curing the concrete with pressurize water vapor can increase the strength and the shorten the strength gaining of concrete very very much as per my experiences.specially when we need a high speed strength gaining in pre tentioned concrete slabs
I don't think you can simply say one results in a higher strength than the other because they are two different methods of curing concrete. Curing compound theoretically traps water and prevents loss of water during the concrete for the curing process. Using water to cure concrete essentially replaces water loss, to insure that water is available for the curing process. If both processes are done properly, it should not have an impact on the strength. What I have seen is curing compound manufacturers using wording like, increases strenght over improperly or uncured concrete. No kidding? One could just as easily say if you cure concrete properly, it is stronger than if you don't. One advantage curing compounds do provide is increased tensile strength to help reduce heat cracking and surface cracking. I have always been told strenght charecterstics depend on two things, the mixture design and the placement. If you design it properly and you place it properly, you will typically get the desired end strength. Curing is part of the equation. If you do it properly with curing compound or water, you'll likely get typical results.
yes, Curing compund is only put on the service of the concrete to create a tension on the surface so water evaporates less.
If you change the water in the mixure it will effect the complete mixture
Well i think so there will be no differnce as the mixture is same and ur only purpose is to cure that not to change its mix properties so that why thre will be no drastic effect
