“…13 Currently, the vast majority of these materials are destined to landfills, although some studies have already pointed out their potential for use in cementitious ceramics. 20 Thus, governments are expected to move forward towards a circularity of the economy for the management of the industrial solid waste, enabling many industries to properly use or dispose their by-products in other production chains. This circular economy approach, based on the reinsertion of waste in the production cycle, not only minimizes the waste disposal in the environment and optimizes the raw materials extraction, but also makes the manufacturing industry more competitive.…”

Cementitious ceramics, produced from the hydration of cement and hydrated lime, are responsible for a great deal of damage to the environment due to the high emission of CO 2 that occurs in the production of cement and lime. Therefore, the objective of this work was to substitute the hydrated lime with a combination of clay residue and marble waste extracted from ceramic and ornamental rock producing industries, respectively, which constitutes a circular economy for the ceramic industry related to masonry applications. Ceramics were produced in the proportion 1:1:6:1.5 (cement:lime:sand:water), through the molding procedure, and were studied by replacing hydrated lime with 100% clay residue and 100% marble residue, in addition to stoichiometric calculated parts of marble to clay. The molar ratios used were 1:1, 1:2, and 2:1 (marble:clay). Tests of consistency, incorporated air content, water retention, compression strength, density, water absorption by capillarity, adhesion, and electrical resistivity were performed. The results obtained demonstrate that the use of residue of marble and clay together, as long as they are correctly balanced, provides a high gain in technological properties, enabling the circular economy of cementitious ceramics, mainly for the composition 1 marble:1clay, which presented the best properties, both in the fresh and hardened state. The economic analysis carried out proved the financial gains for the industrial sectors involved (civil construction, ornamental rock, and ceramic).

“…These articles aim to contribute to the sustainable development by making greater use of industrial residuess in the civil construction as mortars 6 , bricks 7,8 , concrete 9,10 , blocks 11 and ceramic grouting 12 . Considering the complexity of degradation mechanisms that impair the useful life of construction products and the high costs of civil works, the evaluation of the durability of a product is certainly one of the most important aspects in the development of a new construction material 13 .…”

Durability of Soil-Cement Blocks with the Incorporation of Limestone Residues from the Processing of Marble

et al. 2018

The great environmental impact caused by mineral production has forced mining and ornamental stone industries to acquire new concepts and technical solutions in order to develop eco-friendly and sustainable activities. In this context, this work aims to study the durability of soil-cement block with the incorporation of limestone residues from the processing of marble as an ornamental stone. Specimens were prepared with 30, 40 and 50 vol% of residues added to the soil-cement mixture and analyzed for their physical, chemical and mineralogical properties. After the curing period, the specimens were subjected to mechanical analysis and the established experimental program showed that the addition of residues in the mixture becomes feasible for the preparation of soil-cement blocks, exhibiting improved results when compare to a reference block without residues.

“…The adoption of practices for a reuse and recycling of different type of residues to avoid environmental pollution is mostly desirable as it contributes to sustainable development 11 . The civil construction industry appears as the best solution to overcome this environmental issue and the incorporation of residues in mortars can result not only technical advantages but also cost reduction of the fabricated products since the residues are considered waste materials for the industry 12 .…”

Evaluation of Mechanical Properties of Sealing Mortar with Partial Replacement of Portland Cement by Stone Crusher Waste

et al. 2019

Civil construction is one segment responsible for major environmental and social impacts. Among its raw materials, Portland cement, which is produced by the burning and subsequent grinding of a composition of clays and limestones. This manufacturing process causes great environmental damage, both by the exploitation of deposits and by the process of clinkering (burning of raw materials), which emits a significant amount of CO 2 in the atmosphere. Therefore, there is a need for research on materials that reduce these impacts on the environment and that can be used by civil construction to the partial replacement of cement. Thus, this research had as objective to produce settlement mortar through the partial replacement of the Portland cement by filler powder, in different proportions and to study its mechanical properties. The results show that the partial replacement of the cement by the residue has acceptable behavior in the mortar.
