“…The same trend is also seen in other grades of concrete. The results in [14,22] also showed that 1 day curing at 28 days has less strength when compared with 28 days curing strength, almost the same percentage of loss is noticed. In Figure 13, it is also noticed that the samples kept outside the laboratory have a little bit higher strength when compared with the samples kept inside the laboratory.…”

“…At 7th day the samples cured for 1 day have more water loss as compared with the samples cured for 6 days. The same trend of water loss for grade 40 and grade 60 resulted in [14,22]. The samples kept outside the laboratory after each curing day did not show a uniform trend of water loss as shown in Figure 6.…”

“…The density of hardened concrete was measured according to BS 1881-114:1983. Water loss measured by weighing the sample every day until water loss became constant [14,22,23]. The compression strength and modes of failure on cubes were tested according to BS 1881-116:1983.…”

“…On the other hand, in real life practice, in countries where temperature is high and relative humidity is low, concrete is subject to major water loss from the exposed surfaces [12]. Improper curing of concrete occurs almost everywhere but especially it occurs on vertical members, inclined members, areas where water is in low quantity or not accessible for continuous curing [13][14][15] and where curing cannot be properly supervised [10].…”

In real applications, 28 days are regarded as proper curing time for concrete. There is a self-evident need to minimize the duration of curing days. For this purpose, this research investigates 1 to 7 days of curing and compares it with concrete cured for 28 days. Three grades of normal concrete strength grade 30, grade 35 and grade 40 were made. After curing, two exposure conditions were applied to the concrete, inside laboratory-controlled environment and outside environment. Results indicate that slump increases with cement content in DOE method at constant water content. The concrete density in all grades reduces when the concrete is subject to inside exposure in comparison with outside exposure. Water loss from concrete reduces with increase in curing days in all concrete grades. Compression strength of all concrete grades increases with increase in curing days. For the uniformity of concrete, ultrasonic pulse velocity indicated that with an increase in curing days, concrete becomes denser and a bit void. Results showed that an increase in curing days also improves the surface quality of concrete. The significance point noticed is that there was not much difference in the concrete properties between 7 days of curing and 28 days of curing in all grades.

“…Unlike traditional curing, self-curing concrete removes moisture from the concrete's water evaporation, allowing it to hold more water. Polymeric glycols and paraffin wax are examples of hydrophilic materials that self-cure [3,4]. Liquid paraffin wax as a self-curing agent, this study compares it to alternative curing regimens that simulate traditional curing procedures [5].…”

Construction industry concrete used heavily. The building industry relies heavily on coarse aggregate (C.A.). Due to the lack of C.A., artificial aggregate known as Ferro silica slag (F.S.S.) is the predominant alternative material. The Use of F.S.S. increases concrete strength and lowers construction costs. The strength of concrete is determined by how long it is allowed to cure. Because of improper curing, the hydration of cement problem can be solved by employing a self-curing mechanism. It’s possible to use paraffin wax Light and Heavy in Concrete have a variety of beneficial effects on S.C.C.’s fresh and hardened concrete qualities. The immersing curing agent is a material that retains Water and reduces evaporation; the self-curing admixture incorporates concrete after the standard setting of concrete on account of increased water retention capacity and compares to internally cured concrete. It gives inside assuaging, known explicitly as “self-curing concrete,” in short, less or no external curing is required in another way if outside mitigating may cause better warmth of hydration. Light molecular weight and high molecular weight are two examples of self-curing liquids that can boost the strength and serviceability of concrete. In this investigation, the percentage of paraffin wax in M25 grade concrete was altered from 0%, 0.1%, 0.5%, and 1.0% and compared to internally cured concrete(I). The replacement of coarse aggregate with the optimum amount of F.S.S. Paraffin is then added to concrete in a liquid form, resulting in varied dosages. Based on the literature, the optimum percentage of F.S.S. 40% with paraffin wax light and heavy 1.0% improvement of compression and flexure strength of concrete. Ultrasonic pulse velocity (U.P.V.) and Rapid chloride penetration tests (RCPT) were used to determine dense microstructure and enhanced durability of concrete.

The present study is focused on the compressive strength, water retention, and workability by varying the percentage of poly ethylene glycol 200 and liquid paraffin wax from 0% to 1% by weight of cement for self‐compacting concrete and compares it with conventional SCC. Percentages of 0.1%, 0.5%, and 1% (in proportion to the weight of cement) were adopted in the study. The comparison was done in a grade concrete and with cases such as indoor curing and water‐based curing. Slump‐flow test and V‐funnel tests were carried out on the fresh concrete to evaluate the workability of concrete. Concrete weight loss with time is evaluated to determine the water retention capacity. Compressive strength of cube specimens was conducted at the end of 7 and 28 days of curing. The durability of the concrete was assessed by immersing the concrete specimens in acids. The fresh properties were satisfied according to EFNARC specifications. Based on the weight loss percentage and satisfaction of compressive strength, the dosage of a self‐curing compound was determined. XRD analysis of the concrete was also performed on the concrete specimens.
