We assess the workability, mechanical properties, and durability of self-compacting concrete (SCC) incorporating silica fume (SF) and fly ash (FA) using tap water and seawater for making and curing.

This paper aims to review the existing literature of self‐curing concrete and some value addition from experimentation done. Self‐curing can be an admixture based concrete.
To mitigate the concrete's decreased strength and increased shrinkage in a dry environment, the use of internal curing and/or self-curing methods has been proposed. Using internal curing, extra water is added to compensate for the moisture loss.
Conventional concrete (a mixture of cement, fine aggregate, coarse aggregate and water) needs proper curing and moisture contents for a minimum of 28 days for good heat of hydration and high strength.
It was suggested that adopting self-curing agents in concrete has a beneficial effect on hydration, improving the mechanical properties, durability, cracking susceptibility behavior, and mitigating autogenous and drying shrinkage.
However, in practice good curing is not easy to achieve all the time owing to water shortage. In such a scenario, self-curing or internal-curing is desirable, where some curing agents are introduced in order to reduce the evaporation of water from concrete, thereby increasing the water retention capacity of the concrete.
The property such as compressive strength and split tensile strength of concrete was examined with normal curing and self-curing at 7 days and 28 days for M40 mixes.

Self-Curing Concrete: Self-curing or self-healing concrete contains special additives that retain moisture within the concrete itself. These additives can help the concrete cure more effectively without the need for external water application, making it ideal for projects in arid regions or where water resources are limited.
However, sufficient curing is not always practical in areas facing water scarcity and concreting work in high-rise structures. So, the development of self-curing concrete has attracted the attention of several researchers (Dhir et al., 1995a, 1995b; Reinhardt and Weber, 1998). Self-curing concrete is usually developed by using pre …
In this concrete, cement replacement with some material like fly ash, metakaolin, ground granulated blast furnace slag (GGBS) etc. because to reduce 5–7% of CO2 emissions in cement and due to the curing of concrete large amount of water is required. To overcome the high consumption of water it is needed to study the self-curing concrete.

The aim of this paper is to explore the crystalline admixture impacts on the self-healing capacity of concrete by either partially or entirely resealing the cracks and as in some cases to show recovery of mechanical properties. The study takes into account both high-performance and stan-dard strength concrete fibre-reinforced cementitious concrete.
Self-desiccation and autogenous shrinkage of high-strength concretes is one of their drawbacks which cannot be readily accommodated by conventional curing. The concept of internal curing using lightweight soaked aggregates, to provide internal reservoirs of water which enable uniform curing of the whole cross-section, has been …
There are many self-cured agents like Polyvinyl Alcohol (PVA), Sodium Lignosulfonate (SL) and Polyethylene Glycol (PEG) etc. using which concrete is made self-cured. By using self-curing concrete in construction, we can also save a lot of money. Now a days, potable water is hardly available for drinking, so how we use it for curing.
In the present study, the combined effect of super absorbent polymers and mineral additives, the calcium source provider, on the self-healing properties of self-healing lightweight concrete was investigated.
The desired performance of concrete in the long run depends on the extent and effectiveness of curing [1 & 2]. In the Indian construction sector, curing concrete at an early age is a problematic issue because of lack of awareness or other unavoidable circumstances prevailing on concrete construction sites.
I. INTRODUCTION Proper curing of concrete structures is important to meet the performance and durability requirements. In conventional curing this is achieved by external curing applied after mixing, placing and finishing.

Concrete curing methods include water curing through ponding, spraying, or wet covering; moisture retention with plastic sheeting or wet curing blankets; membrane curing compounds forming a film to reduce evaporation; and steam curing for accelerated hydration. These methods maintain moisture and temperature, supporting optimal …
