Abstract

Concrete is a material that widely used as building components. Concrete has a great strength as a construction material and it is easy to change into other materials accordance with needs. One of the uses of concrete is as partition wall where the design of concrete must be lightweight and have good strength. The most common concrete that have being use as a partition wall is porous concrete. Porous concrete is the term for mixture of coarse aggregate (usually sand, gravel or crushed stone), Portland cement and water. Although people commonly use the word “cement” as a synonym for concrete, the terms in fact denote different substances: cement, which encompasses a wide variety of fine-ground powders that harden when mixed with water, represents only one of several components in modern concrete. The raw material to develop this porous concrete are a fine aggregates, cement, lime (calcium carbonate), gypsum, water and polyurethane (additives/blowing agents). In preparing this final year project, the student obtained data from experimental, literature study and internet, while the selections of research methods are based on ASTM testing standards. This project was a laboratory –scale research to determine the optimum composition of the manufacture of lightweight concrete as a porous partition wall application. The preparations of specimens are by using various percentage compositions of mixed materials.
