“…In fact TENORM activity concentration is from 4 to 10 times the limits set for building materials in the European Union. The Venezuelan RM samples having high pH grade (11)(12), toxic metals and radioactive elements with concentration hundred times the soil average value, pose a serious and alarming environmental concern. Nevertheless it might be used for land reclamation, for the construction of dams and embankments, or conveniently reprocess again to extract elements such as iron (content 20 to 50% by weight).…”

“…In the case of samples from the industrial waste BAUXILUM pond (Puerto Ordaz, Bolivar state), high energy resolution gamma spectrometry measurements indicate that radioactive concentration is between 2.0 and 3.5 kBq.kg -1 [4]. Nevertheless the international literature [9] reported its utilization as additives in geopolymers [10], [11], clay material, cements, ceramics, fired and no fired breaks [12]. A review on this subject is given by Paramguru et al [13].…”

Radon exhalation from phosphogypsum (PG) and red mud (RM) samples are of environmental concern. The study is oriented to evaluate by different nuclear techniques, industrial materials cumulated in sites at Morón (PG) and Puerto Ordaz (RM) in Venezuela. RM samples and industrial by products are assessed for its potential use as additives in building materials regarding its radiological health risk. Radioactive matter concentration in RM is up to 11.6 kBq.kg-1. Radon concentration range for RM dry powder is between DL and 2.5 kBq.m-³ and for PG is between 105-340 Bq.m-³. Results indicate that industrial by product before it can be used as additive; require remedial actions to lower the environmental impact. Experimental values are compared with locally available cement, bricks and gypsum building materials.

“…Studies have proved that lightweight foamed bricks can be made from red mud, and these bricks can be envisaged in urban development activities as partition walls in multistoried buildings which lowers the total weight of the wall, the foundation, and the construction cost [10]. e study has proven that the red mud-fly ash-based geopolymer coating to concrete blocks has increased the strength, durability, and thermal stability of blocks with the increment in morality of 6M and 12M [11]. United States Patent 3886244 highlights a method of making burnt bricks in which 50-90% red mud is of mixed clay and water fixing agent [12].…”

Utilization of mine wastes as a building material in the construction industry surmises to environmental and sustainable concepts in civil engineering.The potential environmental threat posed by mining wastes, as well as a growing societal awareness of the need to effectively treat mining wastes, has elevated the subject importance.The present research proposes a method of producing bricks that is both cost effective and environmentally benign. The research is based on the geopolymerization, known to save energy by obviating high-temperature kiln firing and lowering greenhouse gas emissions. The methodology encompasses the mixing of red mud and iron ore tailings in the range of 90% to 50% with a decrement of 10% with GGBS in the range of 10% to 50% with an increment of 10%. The raw materials and the developed composites have been tested as per Indian and ASTM standards.In addition to tests pertaining to the physical and mechanical properties, XRF, XRD, and SEM tests have been performed for examining various related issues. Based on the result analysis, the compressive strength values showed noticeable differences in case of IOT and red mud bricks with IOT-based bricks showing better compressive strengths.

“…Geopolymers have a wide range of applications due to their useful properties, such as their resistance to acid/sulphate attacks [22][23][24], freeze/thaw [22,25], and high temperatures [22,26]. In the construction sector, geopolymers are referred to as green concrete [27,28] due to their ability to reduce CO 2 emissions and lower production energy [21].…”

This paper presents an economic analysis of manufacturing geopolymer bricks for use in the construction sector. The manufacturing processes of both geopolymer bricks and traditional fired bricks were investigated. For this study, we collected and analyzed all phases of geopolymer brick production from the extraction of raw materials to storage. Seven formulations of geopolymer bricks based on clay and waste bricks were analyzed. We considered the cost of raw materials and logistics operations in the production line of brick manufacturing. The results of this study prove that the manufacturing cost of geopolymer bricks based on clay provides an economic gain of 5% compared to fired bricks for the same compressive strength of 20 MPa. In the case of waste bricks, for the same production cost, the compressive strength of the geopolymer bricks is double that of fired bricks. Hence, this study shows the economic interest in the industrial production of geopolymer bricks. It also confirms that future research is needed that focuses on necessary changes to the current industrial production chain required for the manufacture of geopolymer bricks.
