Smart Morta Care is a chemical admixture which is added to concrete mixtures to improve work ability and strength by helping the cement to react and cure completely. Unless the mixture is â??starvedâ?? of water, the strength of concrete is inversely proportional to the amount of water added or water-cement (w/c) ratio. In order to produce stronger concrete, less water is to be added, which makes the concrete mixture less workable and difficult to mix, necessitating the use of Smart Morta Care for good work ability.
