The amount of construction waste in Western Australia increases annually, whilst natural rock aggregate is in shortage. This research focuses on whether recycled concrete, derived from various sources such as by-products from the processes of manufacturing ready-mixed concrete and waste from construction and demolition (C&D), is a viable option for use as a base and sub-base course material in road building in WA. A series of laboratory tests were conducted to determine the physical, engineering and performance properties of selected research materials to evaluate their respective potential utilisation. The results demonstrate that the concrete waste materials selected from the companies: Holcim Ltd, All Earth, Capital Demolition and C&D Recycling are suitable for use as base and sub-base layers of flexible pavement in Western Australia.

Over 50% of this waste is commonly sent to land-filled sites, resulting in the impact on the limited capacity of land-filled sites. Nowadays, the sources of virgin natural aggregates aredepleted by increases in demand of using a virgin material in building and infrastructure, construction and maintenance facilities. This depletion leads to the utilisation of crushed concrete waste to replace natural aggregates in road and highway construction. Of key significance of this study is to present alternative materials for road and highway construction on the production of the proper guideline for road base by using crushed concrete waste.

Every year for a heating and producing electricity, in the coal fired electric Power Plants in Mongolia, 2.7 million tons of a coal has used and have been producing approximately 531 thousand tons of coal combustion by product per year. These burned coal and coal combustion by product a quantity are increasing year to year. The objective of this study was to determine the possibilities of an effective usage of the coal combustion product of Power Plant III in Ulaanbaator. The investigation is included the determination of a classification of a coal ash which is producing in Mongolia , compared to other countries, the optimal mix proportion to produce aerated cellular concrete (ACC) which is a thermal insulation lightweight concrete with a fly ash. According to laboratory exp...
