Compressive Strength Of Concrete

Abstract As a material of construction, concrete have a good compressive strength but low tensile strength. From the previous study, reducing the tensile weakness of the concrete using empty fruit bunch (EFB) of Palm for the concrete mix have a significant result. But in contrary, the use of this fiber decreases the compressive strength of concrete. This research aims to optimize a mixture of glass powders on EFB fiber as a solution to increase the compressive and tensile in strength of concrete as well. The fiber material requires pre condition treatment which is soaked in 10% NaOH for 6-10 hours, then is followed with drying for 24 hours and finally cutting into 4 cm pieces long. Using glass powder as mix design with fiber material which is substitute for fine aggregate in concrete. Variation of 0.25%, 0.5%, 0.75%, 1%, 1,25%, 1,5%, 1,75%, and 2% fiber material mix up with 10% glass powder used for concrete specimens with a diameter of 15 cm and a height of 30 cm at the age of 28 days testing. The results of this study shows an increase in the compressive and tensile strength of concrete compare to normal concrete. The optimum compressive increase 21.02% of normal concrete which is 24.87 MPa. Meanwhile the tensile strength an increase of 31,78% of normal concrete which is 3,11 MPa using 1% fibre and 10% of glass powder. Hence, using glass powder mix in EFB to increase compressive and tensile strength of concrete can be developed optimally in the future.

Initial Idea

Title: The Effect of Using Mediteran Soil as Cement Substitution Materials in Compressive Strength and Tensile Strength of Concrete Concrete is a composite material (mixture) of cement, fine aggregate, coarse aggregate, and water. The potential of limestone in Indonesia is very large, reaching 28.678 billion tons which is the main ingredient in the cement manufacture. In the long run it will be depleted because it is a non-renewable natural resources. So to reduce the use of limestone the utilization of Mediteran soil as a substitution for some cement in the manufacture of concrete is required. The initial idea is based on the chemical composition contained in the Mediteran soil almost identical to the cement, which is carbonate (CaO) and silica (SiO2). The purpose of this research is to reveal the influence of substitution of Mediteran soil by 20% and 40% in the compressive strength and tensile of the concrete at age 3, 7, 14, and 28 days with the number of test specimen each 3 pieces on each variation in 10cm x20cm cylinder with planning of concrete mixture refers to SK SNI method T-15-1900-03. The type of research used is quantitative with the experimental method of laboratory test and data analysis of comparative method and regression. The results show that compressive strength and tensile strength of concrete using Mediteran soil substitution comparable to  the strength of normal concrete with dry treatment. In the composition of 20% Mediteran soils decreased by 51.35% or 7.9 MPa (compressive strength) and 30.60% or 0.93 MPa (tensile strength). While the composition of 40% Mediteran soil decreased by 43.78% or 9.13 MPa (compressive strength) and 2.24% or 1.31 MPa (tensile strength).

Compressive Strength Of Concrete

Aggregates used in concrete are fast depleting natural resource and the quarrying of which is causing environmental issues. Hence, the use of aggregate from alternate sources such as from waste discarded glass, from foundry sand discarded after metal casting process and sea shells is investigated. Compressive strength of concrete with glass powder, foundry sand and sea shell is studied individually. Concrete is cast with glass powder and foundry sand as 5%, 10%, 15% and 20% replacement of fine aggregate and with sea shell as 5%, 10%, 15% and 20% replacement of coarse aggregate individually. It is observed that compressive strength of concrete decreases with glass powder, foundry sand, and sea shell. Fine aggregate replaced by 10% glass powder, 10%, foundry sand and coarse aggregate replaced by 10% sea shell have the least decrease in strength when compared to control concrete mix.

The need for housing is more higher along with the times and this is also a factor to increasing for concrete needed for building  development. The more concrete that is produced, the more cement is needed for construction.Concrete is a composite material (mixture) of several materials, the main ingredient which consists of a mixture of cement, fine aggregate, coarse aggregate, water and or without other additives with a certain ratio. Utilization of waste carried out in this study is to utilize corn cobs waste which is commonly found in the outskirts of the city of Medan. By utilizing this waste, it is hoped that it can reduce the accumulation of corn agricultural waste and also increase public insight about how to treat corn cobs waste into other forms. In this study, a concrete trial was carried out by adding corn cobs ash waste to concrete which aims to find out whether corn cobs ash can increase the compressive strength of concrete with variations in the percentage of the mixture of 0%, 3%, 6%, and 9% of the cement weight. The compressive strength value of normal concrete (25.45MPa), while with the substitution of corn cob ash 3% (21.96 MPa), 6% (18.56MPa), and 9% (16.45MPa). So it can be concluded that the resulting compressive strength exceeds the planned compressive strength and the optimum substitution value of corn cobs varian is at the 3% variant, namely 21.96 MPa.
