| Increasing social awareness of environmental and natural recourse conservation fosters a search for alternative solutions which would alleviate the impact of waste on human health and the environment. Construction and Demolition Waste (CDW) raises an environmental problem due both to the lack of prevention in their production process and little use of recycled material. In order to improve this situation, over the last years the new legislation on the CDW has entered into force, fostering the recovery of waste at its end-of-life and incorporating a study on CDW management during the planning process and a plan on CDW management during the construction phase. The main conclusions arising from the study are: -In summary, masonry mortars fabricated using 1:3:0,5 proportion, incorporating additive, may contain up to 45% of ceramic and concrete RA, complying with the requirements established by the Spanish standards. -Masonry mortars fabricated using CEM IV binder, with 1:3 or 1:4 compounds proportions can incorporate 100% of three types of analyzed RA, complying with the requirement established by the Spanish standards. -Recycled mortar price is lower than the price of mortars fabricated with natural sand in case of all proportions and types of binder that were used in the study. T-he level kgCO2eq produced as a result of mixed RA fabrication is 4734.15 kgCO2eq per one ton of material and this value is lower compared to the traditional mortar. | |
