The use of Partial Glass Powder as Cement Replacement in Concrete M20 Grade on Mechanical Strength

Abstract

surely glass powder in concrete can be considered one of the most important or relevant fibers as partial replacement aiming to change or improving the properties of concrete. This work was made in the endeavor to know the influence of glass powder when is mixed or replacing cement in concrete using proportion 0%, 10%, 20% and 30%, using m20 grade of concrete. Considered two factors as age and mix proportion, was found the compressive results, also the result of tensile and flexural strength results at 3 days, another one at 7 days, at 28 days and 90 days curing concrete, the study was conducted, using cubes specimens after testes was found reporting that using glass powder in the m20 grade of mix design of concrete as cement replacement shows many advantages in its application on concrete, not only in reducing the co2 emissions to earth’s atmosphere as is written on the first part of this work but also the result show that the proportion up to 20% can improve its compressive strength in concrete, in terms of flexural strength was found increasing up to 10% of glass powder when used in concrete and was found also the optimal proportion in split tensile at 20% of glass powder.
