Ultra High Performance Concrete - A Technical Study

Abstract

The obligations imposed on the construction sector enhanced awareness of various concrete difficulties. These problems include the unevenness and instability of the matrix, as well as its poor durability, high weight-to-strength ratio, low ductility, and low tensile to compressive strength ratio. In 1994, employing an optimum particle size distribution of cement in combination with fine and ultrafine particles was discovered to enhance the compressive strength of concrete to higher than 120 MPa by increasing the compactness of cementitious matrix can increase the compressive strength of concrete elements. The resulting concrete is known as ultra-high strength concrete, and it is distinguished for its great durability, self-compatibility, and high strength. The concept of UHPC was first introduced by Larrard in 1994. This technique has enabled the construction of concrete structures that are lighter, larger, or have a greater span than conventional designs. It is a potential construction material for future sustainable and resilient infrastructure. This technology's primary principle is the use of methodical remedies to get beyond the inherent problems with traditional concrete.
