CHAPTER construction. A rectangular shape usually made out

CHAPTER IINTRODUCTIONINTRODUCTIONWaste management is an act where in proper collection and disposal of waste must be performed. This will help maintain not only the cleanliness of the community but also to improve the health of the people. Unfortunately, this is not well practiced in the Philippines. The landmass of earth is not expanding. And so is the landfill for garbage but the quantity of waste are still increasing.Waste are unusable materials.

These are things that can no longer be use due to its damages and other reasons. There are different kinds of waste and agricultural waste is one example. The usual product can be seen agricultural wastes are rice husk, and coconut wastes that are known for things that can be used in making eco-friendly bricks.Bricks are materials used in construction. A rectangular shape usually made out of clay. Famously known as clay bricks that combines 55% of silica.No living creature doesn’t silica.

Animals and plants contain this for structural purposes. vegetable, known as a healthy food for human contains silica.In the public market, vegetable are the common products that can be bought. For some reasons, some vegetables when brought to the market sometimes the vegetables are no longer fresh and damaged. They are usually thrown away. Sometimes if the owner is irresponsible, he will just leave the defective vegetable anywhere. These vegetables that are no longer can be use are called vegetable scraps.Since silica is found in vegetables, and one of the chemical components of clay brick is silica, the researchers were able to conduct a study to know if vegetable scrap can be used as a component in making bricks.

Statement of the problemThe study aims to determine whether vegetable scrap can be an effective component in producing eco-friendly bricks.This study sought to answer if there is a significant difference between Treatment one is the commercially made clay bricks that was bought from the store and treatment two (2): is the bricks made with vegetable scraps. The powdered vegetable scraps were mixed with tap water, sand, and cement. in terms of:Water absorptionDurability of bricksSignificance of the studyThe primary beneficiaries of this study are:The vegetable vendors. For them to know how to minimize the amount of waste materials particularly the biodegradable ones, which can be used in making bricks. And this study will give the vendors new ideas on how to make money out of vegetable scraps.The brick producers that is trying to make an affordable brick and will not have a hard time on finding materials and components in making brick which are affordable too.Last, the community.

It can help lessen the pollution and diseases around the environment due to improper waste segregation.Scope and Delimitation The main goal of this study is to determine whether the bricks made of vegetable scrap, sawdust, water and cement are cost effective and effective in terms of durability and water absorption.The research was conducted at Antao’s residence located at San Roque, Zamboanga City.

The vegetable scraps were gathered from Sta. Cruz Public Market, Zamboanga City.The experiment has only two (2) treatments, three (3) replicates and three (3) samples per replicate making it eighteen (18) all in all to ensure the accuracy of the results. The study lasted for three months days from December 1, 2017 to February 2018 which includes the preparation and gathering of the materials and testing.To compute for the significant difference between the two treatments in terms of water absorption test and durability test, the statistical tool used was T-test for two independent samples at 0.05 level of significance to measure the statistical significance of the data. The limitation of this study is to determine the effectivity of vegetable scrap as the main component for brick making.

The boundary of this research was to extent the use of vegetable scrap for the production of eco-friendly bricks.The independent variable was the application of vegetable scrap and saw dust for making the bricks. The dependent variables were the water absorption of the bricks md the durability of the produced bricks made out of vegetable scrap and sawdust.Thus, this study is only tested and proven for vegetable scrap. There were no other waste materials used in this study.

Definition of TermsCement – another composition in making bricks. Also serves as the binder.Compressor – refers to the tool used to make the bricks intact and compactDurability Test – refers to the method used to determine if the bricks made with vegetable scrap are durableMolding Brick – refers to a strip of wood to form the right shape of the bricks.Recycle – it is the one of the goal of researchers as they convert a thing into something new.Vegetable Scrap – refers as one of the main components in making bricks.Waste Management – an activity that promotes proper disposal of wastes.

Water Absorption Test – refers to the method that is used to determine whether the bricks made with vegetable scrap are water resistant.CHAPTER IIIMETHODOLOGYPreparation of molding box for the bricksFor molding the bricks in to its standard size and shape, the researchers made a molding box made of plywood with the length of eight inches, width of four inches, and a height of two inches as well and nailed together with the use of common nails. The researchers sprayed oil to aid in stripping the form of the bricks. Preparation of vegetable scrapThe vegetable scraps were bought from the public market and collected by the researchers from their own houses. The vegetable scraps used by the researchers were specifically the leftover of any vegetable.

It can be the peelings, the leaves, rejected veggies, and even the flesh of the vegetable. The vegetable scraps were placed in a plastic container. The vegetable scraps were sun dried for nine hours a day for straight one week.

After sun drying, the dried vegetable scraps were grind using the coffee grinder for it to be powdered. Processing of the bricksThere were two treatments. Treatment one is the commercially made clay bricks that was bought from the store and treatment two (2): is the bricks made with vegetable scraps. The powdered vegetable scraps were mixed with tap water, sand, and cement. And when the bricks’ composition was done mixing, the researchers poured the composition in the molding box.

The bricks were sun dried for nine hours a day and lasted for one to two weeks.Measuring of Average weight of the different processed bricksEach brick was weighed using the digital weighing scale. For each treatment, the data of the weight of the bricks were collected and computed using Measures of Central Tendency. Testing of Water absorption of the bricksThe bricks were weighed using a digital weighing scale and the data were recorded. The researchers immersed the bricks into the water for 24 hours. After 24 hours, the researchers then again weighed the bricks.

The researchers found the difference of the initial weight of the bricks and the final weight of the bricks.Testing of durability of the processed bricksThe bricks were brought to the emission center to test the durability of the bricks.
