The Construction and Evaluation of No Fine Concrete Using Waste

Abstract

INTRODUCTION

Pollution is one of the major problems worldwide. It affects other living organisms and causes diseases for humans. Many researchers conducted a study to lessen the pollution. One of the best ways to reduce pollution is to process waste into different helpful materials. The main cause of environmental pollution is the improper management of solid waste material such as plastics and glass. Tons of waste glasses that do not decompose naturally are improperly disposed. As the number of waste glass continues to increase, humans will suffer. In this study the researchers used waste glass powder to make a no-fine concrete that let the water flows through it. The researchers aimed to analyze its compression strength and its permeability.

METHODS

This study is divided into five phases: preparation of materials, pulverization, mixing, construction and testing. The researchers pulverized the waste glass and mixed it to cement to form granules of rocks and then mixed it again in cement for construction. The testing was divided into two which is the permeability and compression strength test. The researchers poured 1 liter of water to the concrete. Then, the researchers also set a time to see its permeability. Moreover, the researchers improvised a compression strength test with the use of a300 kg vehicle and rolled it upon the concrete.

RESULTS

The researchers found out that the no-fine concrete (NFC) is able to let the water flow through it in a short period of time. However, in the compression strength test the waste glass can't reinforce the NFC since in the first and second trial it broke at the second time the vehicle rolled upon on it. But in the third trial it broke at its first passing.

DISCUSSIONS

The results show that the constructed no-fine concrete is effective in terms of the permeability test. It is proven that it is possible to use a waste glass powder to make a no-fine concrete. On the other hand, it is recommended by the researchers to make the no-fine concrete thicker for the good outcome in terms of its compression strength. The researchers found out that the constructed no-fine concrete has a less compression strength compare to a normal concrete because the granules of rocks are not compact to each other.
