Lightweight Concrete Mixed with Superfine Crumb Rubber Powder Part 1: Insulation Properties
Abstract:
In this study, insulation properties of lightweight concrete mixed with commercialized superfine crumb
rubber powder is investigated. Crumb rubber produced from rubber reclaimed plant has been used widely in several applications such as pavement, blocks, rubber tiles, sealant, supplement fuel etc. Because of the grinding during the manufacturing, crumb rubbers are found in various sizes from several millimeters to microns. The smallest size is about 500 to 600 micron. In this experiment, the superfine crumb rubbers are mixed with concrete by replacing fine aggregate at the rate of 10%, 20% and 30% by weight. The main role of crumb rubbers powder is to replace fine aggregates to produce lightweight concrete. However, because of its small diameter and dense property, crumb rubber powder will also act as a filler to fill small voids in concrete to reduce water absorption and porosity. Also, the decrease in density results in better thermal and sound properties.
