Abstract

This research describes the Dir-Utror volcanics in terms of geochemical analysis and compressive strength results to determine their Pozzolanic properties. Adding pozzolana to cement mortar enhances compressive strength by providing a supplementary binding material that reacts with calcium hydroxide to form additional cementitious compounds. This not only improves the overall durability of the mortar but also reduces the risk of cracks, making it an economically viable solution for constructing robust and long-lasting structures. For this purpose, this research concentrates on exploring the Pozzolanic characteristics using the X-ray Florescence technique, to illustrate chemical composition, and compressive strength test using 2 inch or 50 mm mortar cube. According to chemical composition and compressive strength results and by comparing it with the standard cube compression results with Ordinary Portland Cement (OPC), these materials are suitable to use as an additive or substitute for cement replacement. Four different samples were collected from the same region three of them, at 28 days of age, gave satisfactory results, while a single sample (sample 2) had less compression result than the standard cubes, cured for 28 days, according to the graphs’ trend lines. A total of 78 (2-inch) cubes were made, 6 considered to be standard (OPC) and 72 for 4 different samples. Three cubes for each ratio, such as by 15%, 25 and 35%, have been prepared and have taken the average value for each Pozzolan-ratio sample. The 1st series, 36 Pozzolan cubes’, compressive strength results were conducted after 14 days of age which was not as satisfactory as the 2nd series cured for 28 days of age.

Abstract

The purpose of this study is to provide Pakistani citizens with Ultra-High-Performance Concrete utilizing locally available resources. In an experimental study, steel fibres are combined with silica fume and rice husk ash when superplasticizers are present. Several different tests were done using completely different volumes and different amounts of ingredients from local supplies and steel fibres to investigate ultra-high-performance concrete. Results show that ultra-high-performance concrete can be produced using locally accessible material. There are differences in the compressive and flexural strengths of the Ultra High-Performance concrete. Every outcome is pleasing. Scanning electron microscopy and X-ray diffraction tests were also used to assess the ultra-high-performance concrete's microstructural analysis. The transition zone between fine aggregates and the cement paste is enhanced by the use of silica, according to X-ray diffraction and scanning electron microscopy test results. Dense packing is one of the main factors influencing concrete strength, and it is achieved by using a low water to-cement ratio. This observation is gained from Scanning Electron Microscopy and X-ray diffraction tests. The steel fibers in ultra-high-performance concrete inhibited the propagation of cracks in the matrix.
