Abstract

The characteristics of concrete are that it has high compressive strength and low tensile strength. To increase the tensile strength of concrete, it is necessary to use fiber as a constituent material for concrete. This study aims to evaluate and compare the tensile strength value of concrete containing sea sand and seawater with or without steel fiber reinforcement stolen by seawater for 28 days, as well as analyze the homogeneity of the concrete mixture. The materials used are composite portland cement, gravel, sea sand and seawater and 3D 80/60 BG dramix. Determination of the volume fraction of steel fibers is 0% - 2.5% to the weight of cement. Testing the tensile strength of concrete using the split tensile strength method. The results tensile strength showed that the value of seawater concrete increased due to the reinforcement of steel fiber, with the addition of 2.5% steel fiber, which was 17.8%. The tensile strength value of seawater concrete increased due to the reinforcement of steel fiber, with the addition of 2.5% steel fiber, which is 24.2%. Overall, all test specimens showed uniformity or homogeneous amounts of gravel and steel fibers in all four cross-sectional areas.

Abstract

In quantum physics, understanding compressed matter brought to extreme states, such as those found inside neutron stars or planetary cores, is the key to unlocking mysteries about the structure and behaviour of matter at a fundamental level. Quantum Optics, as a tool for manipulating and measuring particles on atomic and subatomic scales, offers new methods for investigating properties of compressed matter that are inaccessible through conventional techniques. This research aims to develop Quantum Optics techniques that are more efficient in characterizing and manipulating compressed materials to better understand materials' mechanical and electronic properties under extreme conditions. This research method combines laboratory experiments with sophisticated mathematical modelling techniques. The experiments involve using high-intensity lasers and ion traps to generate and measure compressed states of matter. Mathematical models, supported by computer simulations, predict experimental results and provide theoretical insight into observations. This research shows that using adapted Quantum Optics techniques can achieve greater control over compressed materials and measure their properties with unprecedented accuracy. This includes revealing electrons' behaviour under high pressure and extreme temperatures. This research concludes that innovative Quantum Optics techniques can provide new and significant insights into the properties of compressed matter. This research advances the field of Quantum Optics and expands our understanding of condensed matter physics and astrophysics. It also paves the way for developing new technologies based on the unique properties of compressed materials.
