Self-Cured Concrete Using Water Retaining Agents

Abstract

This paper discusses the materials used as water retaining agents, the self-curing mechanism, significance, benefits, and drawbacks, as well as the properties of concrete when subjected to the self-curing method. Concrete is the most commonly used material in the construction industry, but it also requires a lot of water for its production, so there is an urgent need for research to minimise the use of water to produce concrete. Objectives, gap identification, problem identification, and their resolutions, as well as the project's future scope. Different water-retentive materials, including porous lightweight aggregates, chemical admixtures, polymers, natural fibres, and pozzolanic, have been used by numerous researchers in a variety of methods. These materials can withstand large amounts of water. These water retaining agents used as replacement with aggregates and cement in terms of their percentage. Results indicate that by adopting water retaining agents to produce self-cured concrete,properties of concrete were improved. It happened rare that two self-curing agents are used simultaneously. Materials used are Superabsorbent polymer (SAP) and Light-weight expanded clay aggregate (LECA) both. Methodology is done M20 Grade of concrete, which is again have rarely used by researchers for experiment, but this grade is most commonly used in commercial buildings as well as in normal houses. Experiments and Results have taken out for conventionally cured concrete and self-cured concrete for 7, 14 & 28 days. Conclusion express that self-cured concrete give more strength and improved properties than conventionally cured concrete.
