material worldwide, second only to water. Among its wellknown properties are its strong compressive and tensile properties. We recommend self-curing concrete as an alternative to immersion in order to prevent water shortages because curing increases the durability of concrete. The purpose of this study is to determine the effects of adding 1% of the weight of polyethylene glycol-400 as an additive to M30grade concrete mix. Internal curing is the method we use when exterior curing is not an option, such as in locations with limited water supplies or restricted access for humans. Internal curing, often known as self-curing, is an essential process in the formation of concrete's pore structure and microstructure.
1.2 Self-curing and its necessity: Self-curing is a method that helps provide more moisture to concrete so that the cement hydrates more effectively and self-desiccates less. When compared to regular concrete, PEG-400 helps reduce water loss in the concrete and increases its water capacity. Because appropriate mixing and placement of the concrete result in strength, conventional concrete requires external curing. Normal hydration can be accomplished by external curing, which involves applying water to the concrete surface. This is because it has been established that proper hydration of cement concrete projects is highly vital to achieving durability criteria. The idea behind self-curing compounds is to decrease water evaporation from concrete, increasing the material's ability to retain water in comparison to regular concrete. It was discovered that self-curing agents for concrete can be made from water-soluble polymers.

1.INTRODUCTION: Because it is inexpensive and has strength and durability, concrete is the most widely used building material. It may be sized and twisted to create bridges, roads, and other infrastructure. Concrete is incredibly hard, resilient, and long-lasting. Any type of building project can benefit from using the most adaptable material. Concrete serves as the main building material for the majority of civil engineering structures. Its great durability, affordability, and ease of onsite manufacturing all play a part in its widespread use as a fundamental building material in construction. The development of concrete's strength, durability, and workability is necessary, just like it is with other technical materials. introduction of admixtures of a new generation. It is possible to get higher grades of concrete with good workability.
2. AIM: M-30-grade concrete contains 1% PEG-400 by weight of cement to provide strength without compromising workability.
2.1 OBJECTIVE:
1.1 Curing: Controlling the pace and volume of moisture transfer from concrete during cement hydration is known as curing. It can be done either during the process of making concrete goods or after it has been put in place, giving the cement time to hydrate. In order for the concrete to reach its full strength and durability, curing must be done for a suitable amount of time, as cement hydration does take days or even weeks rather than hours. Temperature regulation may also fall

To examine the impact of PEG-400, the curing agent, on the strength properties of the concrete.
Analyze the concrete's compressive and tensile strengths. Based on the information, draw conclusions regarding the compressive and tensile strengths of conventional and selfcuring concrete.
Our project's primary goal is to produce concrete with less water while maintaining its simplicity of use and strength-boosting properties.
