“…The fresh SJE was subjected to a litmus test giving a PH of 5, which is acidic. The decrease in compressive strength of concrete cubes with increase in the quantity of SJE was caused by the fact that the components of concrete break down during contact with acid [18]. From the results in Table IV, it can be noted that the content of calcium oxide (CaO) is the most predominant element at 35% followed closely by potassium oxide (K 2 O).…”

“…This happens because the retarding admixtures are mainly based on materials having lignosulfonic acids and their salts, hydroxyl-carboxylic acids and their salts, sugars including their derivatives, inorganic salts such as borates phosphates, and zinc and lead salts. [7,[16][17][18][19]. Admixtures come in various forms and are usually imported and expensive to acquire, hence cheaper admixture materials need to be established from locally available sources [20,21].…”

The characteristics of concrete are influenced by the ratio of water to cementitious materials (w/c) used in the mixture. An increase in paste quality will yield higher compressive and flexural strength, lower permeability, increased resistance to weathering, improve the bond between concrete and reinforcement, reduced volume change from drying and wetting, and reduced shrinkage cracking tendencies. Admixtures are used to improve the properties of concrete or mortar. The current study investigates the effect of Sisal Juice Extract (SJE) as an admixture on concrete durability. SJE contains unrefined minerals which can be used as organic retarders to increase the rate of strength development at an early age. A total of 84 concrete cubes were produced in 7 sets of 12 samples each. One set was the control mix which had zero SJE content. The remaining sets had varying dosages of SJ namely 5%, 10%, 15%, 20%, 25%, and 30%. Twelve beam specimens were also cast and subjected to the three-point flexural test. To establish the effect on strength of concrete, compressive strength was tested at 7, 14, 28, and 56 days while flexural strength was tested at 28 days. The highest compressive strength was achieved at 5% dosage beyond which a decrease in strength occurred for all the higher dosages.

“…Previous studies investigated the use of pure sugar as a retarding admixture, on various types of cements. (Otunyo et al, 2015) carried out an exploratory study on the effect of sugar cane juice on concrete properties such as bulk density, setting time, workability and compressive strength. The study established that setting time was delayed by the partial replacement of water with SCJ.…”

“…67.6% of its constituent is solids, the sugar content is 15.1% while the water content is 20.44%. The decrease in the compressive strength of the concrete cubes with increase in the quantity of SCJ is due to the fact that the components of concrete break down during contact with acid (Otunyo et al, 2015).. Figure 1 shows a plot of the setting time versus (SCJ:water) replacement proportions. The setting time was delayed as the content of the SCJ in the concrete was increased.…”

Sugar cane juice (SCJ) was investigated as a retarding agent in concrete production. Slump values and compressive strength of concrete with partial replacement of water by sugar cane juice was also investigated. The concrete cubes were prepared by replacing water with SCJ in the following proportions 0, 3, 5, 10 and 15%. The cubes were cured, tested and the physical properties of interest in this study were determined. Results show that the final setting time of concrete was delayed with increase in content of the SCJ in the concrete mix. At 0% SCJ, final setting time was 3½ hours, while final setting time at 15% SCJ was 6 hours, reflecting additional 2½ hours setting time. The compressive strength of the (water:SCJ) concrete decreased with increase in the content of SCJ in the concrete mix, up till 10% SCJ content.
