Concrete is one of the most widely used construction materials in the world due toitsstrength, durability, and

adaptability in various structural applications. However, theproduction and use of chemical admixtures in

concrete may have environmental impacts, which has encouraged researchers to explore natural and eco-friendly

alternatives. Organicsucrose, a naturally available carbohydrate, has the potential to act as a plasticizer

significantly affectingitscompressive strength. The findings suggest that organic sucrose can be used as a

sustainableand eco-friendly plasticizer in concrete, which may help in reducing dependency on

syntheticchemical admixtures. This study highlights the potential of natural materials in

developingenvironmentally responsible construction practices.

Concrete is one of the most widely used construction materials in the world due toits highcompressive strength,

durability, and versatility in structural applications. It is commonlyused in the construction of buildings, bridges,

roads, dams, and other infrastructure projects. The main components of concrete include cement, fine

while maintaining adequate workability. Theseadmixtures improve the flowability of concrete and help in

producing high-strengthanddurable structures (Mehta & Monteiro, 2014). However, the extensive use of

syntheticchemical admixtures may have environmental and economic implications. As a result, therehas been

increasing interest in exploring natural and eco-friendly materials that can partiallyreplace conventional

chemical admixtures in concrete production.

Organic materials have attracted attention in recent years due to their potential toact asnatural admixtures in

concrete. Among these materials, organic sucrose, commonly knownassugar, has been identified as a substance

that can influence the hydration process of cement. Small quantities of sucrose can act as a retarding admixture

by slowing the setting

process of cement and improving the workability of concrete (Ramachandran, 1995). Thischaracteristic makes

The increasing demand for sustainable construction practices has further encouragedtheuseof eco-friendly

materials in concrete technology. Sustainable concrete aims to minimizeenvironmental impact by reducing the

use of harmful chemicals and promoting the useofrenewable or natural resources. In this context, the use of

organic sucrose as a plasticizer cancontribute to environmentally responsible construction practices while

maintainingtherequired performance of concrete structures (Shetty, 2005).

Therefore, this study focuses on investigating the application of organic sucrose as aneco-friendly plasticizer in

concrete. The research aims to evaluate the influence of sucroseonthe workability and mechanical properties of

concrete and to determine its potential asasustainable alternative to conventional chemical plasticizers.

Several studies have examined the role of chemical admixtures in controlling the hydrationprocess of cement.

The hydration of cement is a complex chemical reaction that determinesthe strength development and setting

characteristics of concrete. According to (Taylor 1997), the addition of certain chemical compounds can

influence the rate of hydration and improvethe performance of concrete in different environmental conditions.

However, the large-scaleuse of synthetic chemical admixtures has raised concerns regarding environmental

sustainability and long-term effects on concrete structures.

In recent years, researchers have explored the possibility of using natural and organicmaterials as admixtures in

concrete. Organic compounds derived fromplant-basedsourceshave shown potential in modifying the setting

based compounds canact as effective retarders used in very small quantities in cement mixtures. Thesesubstances

interact the hydration products of cement and slow the reactionprocess, thereby delaying the setting time of

concrete.

transportation or placement time is required for fresh concrete. However, excessive amounts of sugar may lead

to significant delays in the setting timeandmay adversely affect the strength of concrete.

(Gambhir, 2013) emphasized the importance of sustainable construction materials andsuggested that natural

admixtures can play an important role in reducing the environmental impact of concrete production. By

replacing or partially substituting synthetic chemical admixtures natural materials, it is possible to develop

more eco-friendly construction practices.

Similarly, (Shetty, 2005) highlighted that the controlled use of organic substances in concretemixtures can

improve workability and reduce the need for additional water. This not onlyenhances the mechanical properties

Previous research studies have mainly focused on the use of chemical admixtures suchasplasticizers and

superplasticizers to improve the workability and performance of concrete. These admixtures are effective in

reducing the water–cement ratio and enhancing the strengthand durability of concrete structures. However,

most of these admixtures are syntheticandmay have environmental and economic limitations used extensively

in constructionprojects (Mehta & Monteiro, 2014).

Although some studies have investigated the influence of sugar and other organic compoundson the hydration

of cement, the research in this area is still limited. Earlier studies mainlyfocused on the retarding effect of sugar

on the setting time of cement rather than its potential application as a plasticizer in concrete (Ramachandran,

1995). Moreover, many of thesestudies were conducted on cement paste rather than on full concrete mixtures,

which createsagap in understanding the overall behavior of concrete containing organic sucrose. Another

importance in recent years. However, limited studies have focused on the useofnatural organic substances such

as sucrose as environmentally friendly alternativestoconventional chemical plasticizers (Gambhir, 2013). This

indicates a clear need for furtherexperimental research to evaluate the effectiveness of organic sucrose as a

plasticizer inconcrete.

Therefore, the present study aims to fill this research gap by experimentally investigatingtheinfluence of

organic sucrose on the workability and mechanical properties of concrete andbyevaluating its potential as an

eco-friendly plasticizer in sustainable construction practices.

The materials used in this experimental study include cement, fine aggregate, coarseaggregate, water, and

organic sucrose. These materials were selected to prepare concretemixtures and to evaluate the effect of

Fine aggregate used in this research was natural river sand passing through a 4.75 mmsieve. Sand helps in

filling the voids between coarse aggregates and improves the workabilityofconcrete. Proper grading of sand is

important for producing a uniform and workable concretemix.

Coarse aggregates of 20 mm nominal size were used in the preparation of concrete mixes. These aggregates

provide bulk and strength to the concrete and help in reducing shrinkage. The aggregates used were clean, hard,

and free from organic impurities. 5.4 WATER

Clean and potable water was used for mixing and curing of concrete specimens. Water playsa crucial role in

the hydration process of cement, which leads to the development of strengthin concrete. The quality of water

used for concrete must be free from harmful substances that may affect the properties of concrete.

The experimental investigation was conducted to study the effect of organic sucrose ontheproperties of

concrete. Different concrete mixes were prepared by adding varying percentagesof sucrose respect to the weight

of cement.

In this study, the sucrose content was added in small proportions such as 0%, 0.5%, 1%, and 1.5% of the

weight of cement. The control mix contained no sucrose, while theothermixes contained different dosages of

sucrose to evaluate its influence on concrete properties. Concrete specimens were prepared by thoroughly

mixing cement, sand, coarse aggregates, water, and the required quantity of sucrose. The fresh concrete was

placed into cube moldsof

standard size 150 mm × 150 mm × 150 mm. The molds were compacted properly toremoveair voids and ensure

slump value. Higher slump values indicate better workability of the concrete mixture (Shetty, 2005). 7.2
