A Review on Experimental Study to Optimize Self-Curing Concrete by Using Light-Weight Aggregates

Abstract

Self-curing concrete, also known as internal curing concrete, is a significant advancement in concrete technology that enhances hydration and performance by injecting more moisture throughout the curing process. In this study, we will apply self-curing chemicals in M35 grade concrete to attain the same strength as traditionally cured concrete. To assist the concrete in curing on its own, we will employ several self-curing agents such as lightweight aggregates and saturated normal weight aggregates, as well as a specific ingredient known as PEG-4000 superplasticizer. We'll look at how these chemicals impact the concrete's mechanical qualities, such as its capacity to endure pressure, tensile strength, and shrinkage. We will also evaluate the endurance of the concrete using a Rapid Chloride Penetration evaluate (RCPT) by varying the quantity of superplasticizer in this mix. A scanning electron microscope will also be used to analyze the small structure inside the concrete. This will allow us to examine how a certain element in the concrete interacts with the concrete particles. This is useful for projects where traditional curing methods, such as spraying water or coating with wet materials, are difficult or prohibitively expensive. Self-curing concrete is a type of concrete that can retain moisture without the need for external assistance. This allows the cement to mix effectively with water, making the concrete stronger, more durable, and less prone to cracking. We will utilize a step-by-step approach to investigate the areas for improvement identified in our analysis of previous studies. First, we will test all of the materials we have chosen in accordance with industry standards. Next, we shall mix concrete in accordance with IS: 10262-2009 specifications. Then, we'll do preliminary experiments and create concrete samples, test them, and compare the outcomes to regular concrete.
