“…Standardization is needed in the building materials industry to ensure the quality of its products (Letelier et al, 2018;Seco et al, 2018). Essential aspects that must be present in bricks such as morphology, dimensions, and compressive strength are generally required to be realized.…”

The regional election in Lampung province has finished. The events left the amount of ex-campaign props such as banner to become waste. The final landfills and the waste reuse system are still an unsolved issue in Lampung province. A study of materials composition is required to find potential reuse of the waste. One of the traditional products in Lampung province is conventional bricks. Previous studies show that mixing local clay with additional materials such as Rice Husk Ash (RHA) could improve its characteristics, especially water absorption potentiality. This study reported the prototype of bricks with banners waste mix produced employing a conventional method. The method obtains the best admixture composition is 0.002 kilograms banner waste/volume 0.125 liters or 0.02% total weight of clay-dough. The morphology of the prototype shows a similar texture with a non-waste mixture of traditional brick. It is burnt-clay red-bricks, which is used as a control in this study. The prototype bricks show smooth texture and nearly flat on all sides. The addition waste composition ratio of more than 0.002 kilograms indicated cracking texture that affects the market tend to buy bricks, which has good appearance and texture. This study also reported that the mixture's effect is decreasing compressive strength, almost 20% from the control sample.

“…As a result, many studies have focused on reducing the environmental damages associated with its manufacturing. Several investigations have been based on one solution which is related to the study of the effects of substituting different concrete constituents with reused materials [3][4][5][6][7].…”

Currently, reduction of environmental effects of the cement industry is an issue of global interest and one of the alternatives is to replace clinker with additions such as volcanic powder. The purpose of this work is to study the influence of up to 400 hardening days of volcanic powder, obtained from the last eruption of the Calbuco volcano (Chile), on the pore structure, mechanical performance, and durability-related properties of mortars which incorporate up to 20% volcanic powder as a substitution for clinker. In addition, an evaluation of greenhouse gases emissions was performed in order to quantify the possible environmental benefits of incorporating the volcanic powder in the mortars. The results obtained indicated that mortars with contents of 10% and 20% of volcanic powder had adequate service properties and improved all durability-related properties overall as compared with those noted for ordinary Portland cement. Additionally, the use of up to 20% volcanic powder makes it possible to reduce the CO2 emissions of mortars by almost 20%, demonstrating the advantages of incorporating this addition in mortars.

“…There are some results that indicate the possibility of producing recycled concrete containing RCA or crushed bricks and used in the construction process where he explained that the presence of these materials within the concrete increases the compressive strength and therefore does not pose any risk in its use as a normal building material [14]. Letelier (2018) concluded that brick powder can be used in the concrete mix by 15% without a significant impact on concrete strength [15]. Marie (2017) found that through the use of RA and in different proportions can maintain the properties of mechanical and physical, concrete and thus can achieve sustainability using RA, but depends on the proportion of use within the concrete mix [16].…”

Developing Sustainable Alternatives from Destroyed Buildings Waste for Reconstruction Projects

This paper examines the huge destruction that has taken place in some cities of Iraq due to the terrorist acts in recent years that led to the destruction of many buildings. It examines some of the factors that encourage the use of residues of these buildings in reconstruction processes, especially the sustainability factor, so that some residues of these buildings can be used as substitutes for natural building materials and find a difference in terms of energy consumption in the case of using natural building materials and again in the case of using the proposed alternatives. In this study, three alternatives were used: 10% recycled fine aggregates (RFA), 100% RFA, and crushed clay brick aggregate (CCBA) to produce recycled coarse aggregates. The results obtained through the use of building information modeling (BIM) technology were compared with the actual consumption of the building in the case of reconstruction using natural building materials. The simulation results were comparable to real data. They were analyzed in terms of the energy consumption life cycle and annual carbon emissions for each alternative. The best alternative was selected from the results obtained from BIM. The best alternative was found in the use of CCBA in the production of concrete roofs and floors. His final model is that the energy consumption was five times lower than the original unit, while the results of carbon emissions were equal as for the electricity consumption decreased from 23,500 kW/h to less than 23,000 kW/h.
