ABSTRACT

Sabalberino, Jesus etal (March 2015) “GLASS WASTE AS ALTERNATE AGGREGATES FOR LOAD BEARING CONCRETE BLOCKS” (An Undergraduate Thesis, Aquinas University College of Engineering, architecture and Fine Arts, Rawis Legazpi City, SY 2014-2015)

The main purpose of this study is to utilize waste glass and help lessen solid waste production especially from glass. The research conducted a comparison between a Concrete Block (CB) with commercial mixture (cement, sand and water) and the CB with Ground glass waste. The research desired to discover the effect of the glass waste added to C mixture in terms of its strength and water absorption. It determined whether glass waste can be an alternative in sand for CB.
The research came up with the idea of utilizing glass waste as a substitute aggregate (fine) for load bearing CB. It also compared the strength of a normal mixed load bearing CB to the load bearing CB with glass waste as aggregate. It addressed concerns regarding the properties of natural aggregates and glass waste aggregates in terms of strength, stability, durability and water resistance. It also to addressed other concerns like the effects of glass waste aggregates in the load bearing CB and the load bearing CB’s improvement in terms of physical properties and water resistance.
The research came up with the different findings the use of the glass waste as an alternative for sand I CB and concluded that glass waste produces lighter CB , rougher in texture, and brighter in color. The research also concluded that waste glass passed the gradation test requirement for fine aggregates and glass waste as aggregates increased in water absorption.
The research arrived at a desirable result and recommended that the use of waste glass as an alternative for fine aggregate is acceptable based on the test results that they have conducted. It recommended having a further study regarding the use of the waste glass as partial replacement for concrete hallow blocks.
