Relevansi Mata Kuliah Ilmu Bahan Bangunan terhadap Bahan Bangunan di Dunia Industri

In the current era of the development of the infrastructure industry, the building material industry in Indonesia has developed very rapidly along with the increasing national economic conditions and innovative technological advancements. Given the demands and encouragement from the industrial world, the Building Material Science Course is expected to be a means to shape these competencies by looking at the relevance of the development of innovative building materials, so that graduates are expected to produce students who have up-to-date knowledge and competencies related to materials building in the industrial world. The purpose of this article is to increase knowledge and information related to the development of building materials, especially buildings in the industrial world, through the study of Building Materials Science. The method used is the literature review. Literature study results show that learning from lectures is able to contribute to the increase in knowledge and competencies related to the development of building materials that are relevant to the industrial world, one of which is the Building Materials Science Course. The more competence of students regarding building materials, the building in any form can be easily realized when working in the industrial world.

Alternative Building Materials from Waste

Globalization and urbanization growth are disbalancing the nature by creating technology and by increasing population respectively. Population growth is generating trash including the non-renewable ones. Use and throw objects came into existence and as a result, created wastes. After decades, the waste is generating beyond limits that it has created the mountain like piles in the landfills, which is creating hazards for the environment and human health. A better approach to reduce the waste is to recycle and reuse them as an alternative solution to building material industry. The question which arises here is that if wastes should be recycled or reused; what all are the waste materials which can be reused in building material industry without harming the environment. The recycling of waste materials produces lot of demerits to environment and human health. Polyethylene and rubber tires are being used in preparing the roads, plastic bottles are being used to build walls, fly ash is used in bricks etc. measures are being taken. The research paper will try to do a detailed SWOT analysis to find a suitable reusable waste material for building material industry, which will be environment friendly. The plastic waste, construction demolition waste and transport industry waste are the wastes that can be reused as building materials. The 3 wastes have the ability to withstand calamities and loads, are easy to build with, cheap, clean and has passed the structural tests. The paper intends to provide the information regarding the construction with the help of the 3 materials. This approach will help to manage the waste, build a sustainable environment, lower the greenhouse gases, maintain the natural resources etc.

Brief Analysis on Application of PVC Foam Materials in Building Material Industry

Polyvinyl chloride (PVC) foam materials are good materials that take the place of wood and are widely used in building material industry. This paper analyzes and summarizes the application of PVC foam materials in fields such as thermal insulation materials, concrete-form and resilient flooring and explores the characteristics of PVC foam materials concerned by different fields as well as the key future research & development directions, so as to promote the healthy development and application in building industry.

Mechanical Properties of Fly Ash Polymer Concrete with Different Fibers

The experimental results obtained by studying the influence of different types of fibers on the mechanical properties of fly ash polymer concrete are presented in the paper. The general demand of using wastes found applicability in building material industry because some of them are beneficial in improving concrete properties. The waste additions type fly ash and fibers were incorporated in polymer concrete. The study focused on fibers type glass, polyester, metallic and cellulose. The mechanical properties such as compressive strength, flexural strength and split tensile strength were investigated having in view the type, dosage and length of fibers. The results show that fibers improved mechanical properties in comparison with that of polymer concrete without fibers, the test results being differently influenced by the factors which were considered.

Influence of Firing Temperature on the Quality of Fly Ash Body

Nowadays, over 95 % of fly ash is used as construction products in the Czech Republic. However, around 80 % of fly ash is used for renovation of open-pit quarries and areas affected by human activity. Production of artificial aggregate is the way to use over 90 % of energy by-products in the building material industry. It is necessary to find appropriate combination of parameters of input materials and conditions of production to get optimal properties of aggregate. The paper gives an account of the influence of parameters of fly ash and conditions of firing on the quality of ceramic body made from fly ash. Temperatures of 1050 °C, 1150 °C and 1200 °C were examined. The research focused on the structure of the ceramic body as well as its physico-mechanical parameters.

The Model and Countermeasures of New Building Material Industry Based on the Cyclic Economy

Building material industry can absorb lots of scrap of chemical industry, metallurgical industry and coal industry. Through our further study on the application of cyclic economy in the building materials industry, we initially summarize the co-production models between building materials industry and other industries, such as coal, metallurgy and mining, based on the recycling economy. The models also represent the basic patterns which can recycle mineral resources and reuse energy efficially. We advice some possible countermeasures though analysis of the domestic application of these models in the current problems and challenges.
