Abstract

This study develops and introduces a technology innovation to concrete hollow block (CHB) using shredded plastics from PET bottles, which deviates from its usual use as replacement or substitute to mined aggregates, to an additive serving as reinforcement material to improve its compressive strength. Six treatments with five replicates were prepared with the same 1:2:4 mixture of cement, sand and pea gravel. Treatment 1 (T1) had no added plastic serving as the control treatment. The experimental treatments (T2-T6) were added with different amounts of shredded plastics.

Compressive Strength Test for individual units was done after a 14-day curing period to all blocks using the Universal Testing Machine

    Compressive, Flexural, and Tensile Strength of Concrete

    1.) In this lab, concrete cylinders and beams created from Lab 3 were tested for compressive, flexural, and tensile strength. The compressive strength of the concrete was found by applying an axial load on the cylinder until the cylinder failed. The flexural strength was calculated by subjecting transverse loads at the third points of the beam until failure. The tensile strength of concrete was found from applying a uniform line load along the length of the cylinder until failure. The failure loads of the concrete samples and other raw data from testing was collected onto tables and placed in Appendix A. The notation used throughout the report is shown in Appendix B. Engineering equations used to analyze the data are shown in Appendix C.…

    Rock engineers have commonly used the uniaxial compressive strength (UCS) and Brazilian tensile strength (BTS) of rock for designing surface and underground structures. Determining these rock strengths is timeconsuming and expensive, particularly for the preliminary studies of projects. For this reason, indirect tests such as Schmidt rebound number and, ultrasonic test are often used for predicting rock strength. Since indirect tests require less or no sample preparation and the testing…

    Effects of Concrete Mix Design on Earthquake Resistance

    Effects of Concrete Mix Design on Earthquake Resistance

    To discuss the properties for which concrete is designed, it is necessary to stress that the materials used to make a concrete mix can vary distinctly from region to region, and the methods by which concrete is poured may be significantly different than the typical codes seen in the United States. These variances lead to differences in the quality of mix which can be produced. To analyze the impact of concrete mix design during earthquake reconnaissance, it would be beneficial to become familiar with the typical ingredients of concrete structures in the area in order to assess the general quality of concrete. The type of aggregate used affects bond strength and therefore affects the overall strength and quality of the concrete. One should also note the general practices used for pouring concrete such as the use of vibrators, knowledge of ideal pouring time and conditions, and…

    The confined compressive strength of concrete columns is influenced by several factors apart from the material properties of FRP composites. Parameters such as size and shape of the cross section of the columns, grade of concrete, material properties of FRPC, nature of loading collectively affect the confined compressive strength. These parameters are discussed briefly in the following paragraphs.…

    A Practical Equation for Elastic Modulus of Concrete

    Many empirical equations for predicting the modulus of elasticity as a function of compressive strength can be found in the current literature. They are obtained from experiments performed on a restricted number of concrete specimens subjected to uniaxial compression. Thus, the existing equations cannot cover the entire experimental data. This is due to the fact that mechanical properties of concrete are highly dependent on the types and proportions of binders and aggregates. To introduce a new reliable formula, more than 3000 data sets, obtained by many investigators using various materials, have been collected and analyzed statistically. The compressive strengths of the considered concretes range from 40 to 160 MPa (5.8 to 23.2 ksi). As a result, a practical and universal equation, which also takes into consideration the types of coarse aggregates and mineral admixtures, is proposed.…

    concrete compressive report

    Concrete mixtures can be designed to provide a wide range of mechanical and durability properties to meet the design requirements of a structure. The compressive strength of concrete is the most common performances measure used by engineer in designing buildings and other structures. The compressive strength is measured by breaking concrete specimen in a compression-testing machine. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of N/mm2. Compressive strength test results are primarily used to determine that the concrete mixture as delivered meets the requirements of the specified strength, in the job specification. Compressive strength is often measured on a universal testing machine; these range from very small table top systems to ones with over 53 MN capacity. Measurements of compressive strength are affected by the specific test method and conditions of measurement. Compressive strengths are usually reported in relationship to a specific technical standard. When a specimen of material is loaded in such a way that it extends it is said to be in tension. On the other hand if the material compresses and shortens it is said to be in compression. On an atomic level, the molecules or atoms are forced apart when in tension whereas in compression they are forced together. Since atoms in solids always try to find an equilibrium position, and distance between other atoms, forces arise throughout the entire material which oppose both tension and compression. The phenomena prevailing on an atomic level are therefore similar. On a macroscopic scale, these aspects are also reflected in the fact that the properties of most common materials in tension and compression are quite similar. The major difference between the two types of loading is the strain which would have opposite signs for tensile and compression. Another major difference is tension tends to pull small…

    My Coursework About Starrfa

    Durability of concrete is measured by the ability of concrete to resist many characteristics such as chemical assault, bad weather, and abrasion while maintaining its desired engineering properties. Concretes vary for its requirements of durability having different degrees of durability relying on the properties that are desired and disclosure to the environment. For example, the indoor concrete floor having different requirements from the concrete that is exposed to tidal seawater. Concrete ingredients, they’re proportioning, interactions between them, placing and curing practices, and the service environment determine the ultimate durability and life of concrete…
