Augmented Properties of High Strength Self Compaction Concrete Partially Replaced with Nano Mineral Admixtures

Abstract

The construction industry continually evolves to meet the demand for more robust, durable, and sustainable concrete structures. To improve the mechanical and durability qualities of High-Strength Self-Compacting Concrete (HSSCC), this study examines the application of nano minerals as a partial substitution for cement. Fly ash, Silica Fume, Phosphogypsum, and Alccofine are examples of nanomineral admixtures used to improve concrete performance while reducing the environmental impact of regular cement. The experimental program encompasses a series of laboratory tests to assess the fresh concrete and mechanical attributes of the nano-modified HSSCC. Concrete samples curing for seven, fourteen and twenty-eight days will be utilized for these strength tests. The RCPT test, which gauges chloride ion penetration in concrete for twenty-eight, fifty-six and ninety days of curing, is conducted similarly. Tests like Flowability, LBox, V-Funnel, J ring and V funnel at T5 minutes are among the tests on freshly built concrete. These tests are helpful for determining how well new concrete flows, passes over obstacles and resists segregation. The outcomes show that utilizing nanomineral admixtures dramatically improves the performance of HSSCC. Compressive strength and durability are notably increased, surpassing conventional HSSCC mixes, and the modulus of elasticity shows improvement, reflecting enhanced stiffness, durability and structural integrity.
