SELF CURING CONCRETE BY ADDING NATURAL ADMIXTURES

Admixtures are ingredients other than water, aggregates, hydraulic cement, and fiber that are added to the concrete batch immediately before or during mixing. A proper use of admixtures offers certain beneficial effect to concrete, including improved quality, acceleration of setting time, enhanced frost and sulfate resistance, control of strength development, improved workability, and enhanced finish ability. It is estimated that 80% of concrete produced in North America these days contains one or more types of admixtures. According to a survey by the National Ready Mix Concrete Association, 39% of all ready mixed concrete producers use fly ash, and at least 70% of produced concrete contains a water reducer admixture. In our project lagenaria siceraria is added and the result obtained was higher when compared to the conventional concrete.
