Abstract: A self-curing concrete is given to retain water from the atmosphere from air to accomplish cement concrete hydration that is better. It takes care of the issue that the hydration level of cement is brought due down to no improper or no curing. This unsatisfactory is unacceptable properties of concrete. According to the invention, high-performance self-curing agent about 0.1∼5% water of cement weight of the concrete is added to concrete during mixing. The self-curing agent can absorb moistness from the atmosphere and a short time later releases it to concrete. The self-curing concrete suggests that no curing is required for concrete, or even knows any outside gave water is required in the wake of placing. The properties of this self-cured concrete of this advancement are in any event corresponding to and by a far better than those of concrete with common curing. Hydrogel polymer diapers filament fibers based on of sodium alginate were readied utilizing glutaraldehyde as a cross-linking agent. Alginate was expelled into a fluid hydrochloric corrosive coagulation shower to shape consistent alginic corrosive gel fibers by means of a wet-turning technique. The alginic corrosive gel fibers were got dehydrated exchanging water with dioxin, cross-connected, and then neutralized for better retentiveness. Methodology of this research are to testing used and new diapers hydrogel polymer to chemical reaction. Testing are conducted such as turbidity, pH, colour, Chemical Oxygen demand and Biochemical Oxygen Demand. Result found show that both result give a chemical properties a small range and have no impact to apply as a potential recycle internal curing agent. © 2018 Author(s).
