Abstract null null Geopolymer concretes (geocretes) are considered as eco-friendly materials for various building applications. Geocrete has high early strength, less consumption of natural resources, cost-effectiveness, capacity to form different structural configurations and to remain intact for extended periods without repair works. Meanwhile, geocretes have still exhibited an unstable behavior over time compared to traditional cementitious composites. To overcome this disadvantage, hundreds ...
Abstract null null The waste from the flat glass polishing process for civil construction is generally discarded in landfills. Despite some researchers evaluating its application in the development of alternative building materials, its added value is still a barrier. The objective of this research is to evaluate the physical-mechanical behavior of the addition of glass polishing waste on the durability of geopolymeric mortars to be used for small external structural repairs and their processing...

Abstract null null This article proposes a dosing procedure for interlocking concrete pavements that incorporate ornamental rock waste, with a view to meeting mechanical and molding criteria and ensuring the sustainability of the mineral industry, an economically important sector in Brazil despite environmental issues surrounding its waste generation. The procedure involves evaluating the packing density of the sand, coarse aggregate and waste fines via the minimum void ratio. A simplex lattice ...
The functionalization process usually increases the localized defects of carbon nanotubes (CNT). Thus, the ultrasonication parameters used for dispersing non-functionalized CNT should be carefully evaluated to verify if they are adequate in dispersing functionalized CNT. Although ultrasonication is widely used for non-functionalized CNT, the effect of this dispersing process of functionalized CNT has not been thoroughly investigated. Thus, this work investigated the effect of ultrasonication on ...
The use of the ornamental stone wastes, such as the originated from granite or marble, has been the subject of technological studies that evaluated its application in ceramic and cement materials; however, some complementary assessments, such as its life cycle assessment, are still not well explored in the literature. Therefore, the objective of this study was to discuss the main environmental impacts related to the manufacture of ceramic specimens, comparing conventional production versus the p...

The ever-growing consumption and improper disposal of non-biodegradable plastic wastes is bringing worrisome perspectives on the lack of suitable environmentally correct solutions. Consequently, an increasing interest in the circular economy and sustainable techniques is being raised regarding the management of these wastes. The present work proposes an eco-friendly solution for the huge amount of discarded polyethylene terephthalate (PET) wastes by addition into soil-cement bricks. Room tempera...

The incorporation of industrial waste in polymeric resin is being increasingly considered to produce artificial stones. This incorporation has advantages, such as the reduction of the amount of waste discarded in nature, and added value to innovative construction material. The present work aims to incorporate the glass waste generated from the industrial lamination stage into epoxy matrix for the production of a novel artificial stone, as to be used in civil construction areas, as an economic an...
