effectiveness of PEG-400 in enhancing the self-curing properties of concrete, particularly in terms of strength development and durability.
day-by-day, there is an urgent need to do research work pertaining to saving of water in making concrete and in constructions. Curing of concrete is maintaining satisfactory moisture content in concrete during its early stages in order to develop the desired properties. However, good curing is not always practical in many cases. Curing of concrete plays a major role in developing the concrete microstructure and pore structure and hence improves its durability and performance. Keeping importance to this, an attempt has been made to develop internal-curing concrete by using Poly Ethylene Glycol (PEG-400). In this experimental investigation the strength characteristics of high strength concrete, cast with the self-curing agent PEG-400 have been studied and compared with the corresponding conventionally cured concrete. IS method of mix design was adopted, M50 grade of concrete is designed on trial and error basis. For producing internal-curing concrete trial dosage of 1%, 2% and 3% of PEG-400 by weight of cement was used and tested. It was observed that after implementation of new technique the water consumption for curing was significantly reduced by 100%. The findings of this study provide valuable insights into the effectiveness of PEG400 in self-curing concrete, offering implications for construction practices.
Concrete has long been and will continue to be the most adaptable materials utilized in building for a significant duration of time. Concrete possesses a distinct advantage over alternative construction materials due to its exceptional capacity to assume diverse forms in a range of applications, regardless of whether it is manufactured on-site or produced as a pre-cast product in a factory setting. Over the past twenty years, there has been a significant advancement in concrete technology. The conceptualization of a universe devoid of tangible entities is unattainable. Concrete is an essential component of infrastructures. Concrete is essential for enhancing the structural integrity of buildings. Traditional concrete, consisting of a combination of cement, fine aggregate, coarse aggregate, and water, necessitates a curing process in order to attain the desired level of strength. A minimum curing period of 28 days is necessary to ensure enough hydration and attain the desired level of strength. Inadequate curing can have a detrimental impact on contemporary concrete, which undergoes self-curing by preserving moisture content.

Given the increasing scarcity of water, it is imperative to do research on water conservation in concrete production and building. The curing process of concrete plays a significant role in enhancing its strength and hardness, hence resulting in improved durability and performance. The process of concrete curing involves the maintenance of an appropriate moisture content in concrete during its first stages, with the aim of achieving the ideal qualities. The hydration process occurs when cement is mixed with water, necessitating the presence of water for the purpose of cooling. In the absence of water, concrete undergoes shrinkage, leading to the formation of cracks. Hence, it is important to administer water as a means of treatment for a specific length. In numerous
1.INTRODUCTION Self-curing concrete has emerged as a promising solution to address common challenges associated with traditional curing methods. Conventional methods often suffer from issues like incomplete hydration, surface cracking, and high labor costs. In contrast, self-curing concrete utilizes internal water reservoirs to maintain moisture levels, thereby promoting optimal hydration and improving overall performance. Polyethylene Glycol (PEG-400), a watersoluble polymer, has shown potential as a self-curing agent due to its ability to retain water within the
