Recycling building demolition waste in addition to environmental benefits is also economically interesting. In addressing the environmental issues it is recommended to give priority to recovery and rational utilization of waste with regard to their basic characteristics before disposal respectively storage. Issue of the use of recycled materials in concrete structures and their disposal in the world and in our longer pays much attention. Use and recycling of construction materials is a great asset for more prospective and progressive methods of construction waste utilizations. The program focused on waste management is therefore necessary to reconcile economic and environmental aspects in order to come to an optimal solution of the issue of waste and environmental protection.

Building Demolition

The contemporary 4R concept of waste management, in accordance with the globally spread trend of sustainability, promotes: reducing the amount of waste at the source, reusing of elements and their parts, recycling in order to produce raw material and recovering of the embodied energy. Discarded bricks from building demolition sites considered in this research could be reused, but also crushed in appropriate facilities and employed as aggregate in various cement composites. This paper investigates the possibility of using such recycled crushed clay brick material as aggregate in a prefabricated composite fa?ade panel with the face of stone, which can be used in a ventilated fa?ade system. It describes the production process of a pilot element, and further suggests the details of the fa?ade cladding technology concerning the proposed element, i.e. its production technology options, as well as transport and installation technologies. The paper further displays various design possibilities of the panel closely related to the production technology options, as well as observed aspects of sustainability and cost effectiveness relevant to the application of the proposed fa?ade panel. The research contributes to the contemporary course of sustainability within the construction industry by proposing an example of forming a new prefabricated building element using recycled building demolition waste material.

Some building defects lead to their demolition. What about construction and demolition waste? According to the Waste Act 185/2001 Coll. and its amendment 223/2015 Coll., which comes into force on January 1, 2017, the production of waste has to be reduced because, as already stated in the amendment to Act No. 229/2014 Coll., the ban on landfilling of waste will apply from 2024 onwards. The main goals of waste management can thus be considered: Preventing or minimizing waste; Waste handling to be used as a secondary raw material - recycling, composting, combustion and the remaining waste to be dumped. Company AZS 98 s. r. o. was established, among other activities, also for the purpose of recycling construction and demolition waste. It operates 12 recycling centers throughout the Czech Republic and therefore we have selected it for a demonstration of the handling of construction and demolition waste in addressing the defects of the buildings.

Recently, the construction industry uses the Recycled Concrete Aggregates (RCA)resulting from construction and demolition waste (CDW) to achieve sustainable requirements andeconomic benefits. In this paper, asphalt paving mixes were prepared with RCA instead of naturalaggregates for the base course in flexible road pavements and walking areas used by pedestrians andcyclists. Different asphalt mixes samples were prepared with different asphalt contents to meet therequired specifications. Additionally, several laboratory tests were carried out to assess mixturebehavior including the Marshall test. The results indicated that the mixture made with aggregates ofCDW have met all the requirements of Iraqi specifications of roads and bridges (SORB/R9). Thisinvestigation could be a useful guide for road engineers in designing asphalt mixtures from RCA.

In order to deeply analyze the feasibility of the application of building demolition waste on asphalt concrete, pavement performance of asphalt concrete using different content of building demolition waste was analyzed. Results show that: (1) the addition of building demolition waste increases the asphalt-aggregate ratio of asphalt concrete, and the asphalt-aggregate ratio increases 0.25% with the 10% increase of building demolition waste content; (2) the high-temperature stability of asphalt concrete improved significantly with the increase of building demolition waste content; (3) building demolition waste can improve the low-temperature crack resistance of asphalt concrete, and the optimum content is 30%~40%.

Building Demolition

Demolition activity is deeply embedded in the urban system. In recent times, infrastructural development in Nigeria’s major cities has led to increase in road construction activities associated with demolition of hundreds of houses from which millions of tons of Demolition Waste have been generated. However, it is widely reported in many studies globally that demolition debris is such waste that can be re-used. Though, this is not the case in Gombe due to paucity of information on its composition, size and quantities. Hence, the objective of this study is to determine the volumetric composition of generated demolition debris in Gombe City with a view to knowing the potential quantities available for re-use. The study used both qualitative and quantitative design approach. A simple random sampling technique was employed to select 13 roads which were sub-divided in to Lot 1 (8.33km) and Lot 2 (15.04km) and the period of 2011-2014 was considered for the study. Primary data kept by actors and authorities for the compensation assessment which do not refer to demolition debris quantities were used as the bases for extraction of quantities. Handheld (GPS) instrument was used in establishing coordinates; photographs were taken from different locations showing demolition activities taking place and composition of different materials debris. Results revealed that a total of 1,271 structures were evaluated after partially or fully demolished for street widening and/or to pave way for new road construction, in addition a total volume of 129,993.57m3 of Demolished Debris was generated which composed of 10.00% Concrete, 60.30% Sandcrete and 29.69% clay/mud. In conclusion, there exist huge quantities of building demolition debris from street widening and/or new road construction in Gombe city which can be put in to re-use as a component of urban road construction, where properly managed will go a long way to reducing environmental adverse effect due to excessive exploitation for new material.
