Pulverized eggshell as an alternative in making Portland cement
Introduction
Accordingly, cement, or some form of cementing material is an essential ingredient in most forms of building construction. This has been considered as the vital binding agent in concretes, mortars and renders, and is used for the production of walling blocks and roofing tiles. Since its invention in the first half of the 19th century, Portland cement has been noted to be one of the broadly used cementitious materials. Its dominance over other cements has been in part, due to successful, aggressive marketing. This is despite its clear technical disadvantages for specificalapplications. In addition Portland cement is relatively expensive to produce and is often in short supply in many developing countries. Typically, a rural abourer may need to work for up to two weeks to earn enough money to avail a bag of cement. Hence, they need a cheaper alternative for Portland cements ingredients to make it more affordable. Since the cost of ingredients of Portland cements are very expensive, the government and other institutions are trying to make a better alternative to produce Portland cement. Primarily, the goal of this paper is to provide a project proposal on using eggshells in making Portland Cement.
Institutional Framework:
The aim of this project is to propose an alternative way to produce Portland Cement which is through pulverized eggshells, in this regard, the major national institution involved in this project framework can consider Science, and Technology along with the local community and local authorities in the Philippines.These groups can be considered to have broad ranging abilities in developing and initiating the new discoveries in agricultural sectors.
The proposed project has incorporated many of the suggestions put forward by the agricultural and structure department. .
THEORETICAL & CONCEPTUAL FRAMEWORK:
The researcher theorizes that pulverized eggshells can be used as an alternative ingredients in making Portland Cement.. It is said that the research will conceptualize new discoveries to make a more cheaper but quality cements. The theoretical framework guiding this research is the concept that pulverized eggshells can be used in making
Background Of the Study
Social advantages of alternative ingredients in making Portland cement include the potential for affordable quality housing and the opportunity for local employment generation. The technical as well as economic advantages of alternative ingredients are not lost on architects and engineers from developed countries. Increasingly, architects, are becoming aware of the brittleness associated with Portland cement mortars, for instance, and are now specifying pulverized eggshell as well as re-discovering the ‘lost arts’ of using alternative binders, recent research has enabled the properties of alternative binders to be thoroughly investigated and catalogued. A body of knowledge has built up on the appropriate application of conventional binders such as clay, lime and pozzolanas, not only in the repair and conservation of historic buildings, monuments and structures but also in adventurous and innovative new build applications. However, there are new alternatives such as pulverized eggshells which researcher can use.
Research Design
This study uses the descriptive approach. This descriptive type of research will utilize observations in the study. To illustrate the descriptive type of research, Creswell (1994) will guide the researchers when he stated: “Descriptive method of research is to gather information about the present existing condition. The purpose of employing this method is to describe the nature of a situation, as it exists at the time of the study and to explore the cause/s of particular phenomena.”
The research described in this document is based on qualitative and quantitative method. The qualitative method permits a flexible and iterative approach, while the quantitative research method permits specification of dependent and independent variables and allows for longitudinal measures of subsequent performance of the research subject. During data gathering the choice and design of methods are constantly modified, based on ongoing analysis. This allows investigation of important new issues and questions as they arise, and allows the investigators to drop unproductive areas of research from the original research plan.
