“…Likewise, Mexican standards do not establish a maximum valor of shrinkage. However, other authors have reported values of drying shrinkage between 5.35 and 6.45% [16], while Zhang [11] indicate that bricks with good quality should have values of firing shrinkage below 8%. Therefore, all the bricks manufactured in this work presented a total shrinkage (drying and firing shrinkage) less than 10%; the bricks were crack-free making them useful for the established purpose.…”

This study reports the effect of clear waste glass from bottles added on 20 to 30 wt.% and variable particle size (<500, <300, and <212 μm), into clay mixtures for the handmade brick manufacturing process. The bricks were manufactured with mixtures of clay, crushed glass, and water in different proportions, homogenized, casted in wooden molds, air-dried at room temperature for 72 h, and sintered at 1000°C for 12 h. Total shrinkage, water absorption, compressive strength, microstructure, and phase composition are discussed with respect to glass content and its particle size. The results indicate that increasing the content of glass and decreasing its particle size enhanced significantly the brick properties of water absorption and compressive strength by up to 18.5% and 6.8 MPa, for bricks with 30 wt% and particle size lower than 212 μm. It is proposed that decreasing the glass particle size its surface area increases allowing easier melting of glass by lower energy consumption, reducing porosity and enhancing brick properties.

“…The specific instrument was equipped with a 4W, 50kV tantalum anode X-Ray tube and a high- Error should be considered at 1-2% of the measure estimated, taking into account both inaccurate readings and loss of sediment during the procedure. A selected number of samples were then subjected to SEM-EDS at the Wiener Laboratory (using a SEM JEOL JMS-IT300LV) for a more detailed analysis of binders and aggregates (Love 2017;Zhang et al 2016), and to investigate the elemental composition of the mudbricks. Further investigation included petrographic analysis of the samples through thin section petrography using a polarized microscope Leica DM2700P (Nodarou, Frederick and Hein 2008).…”

Excavations conducted in the context of the Palaepaphos Urban Landscape Project (PULP) have revealed a defensive monument of the Cypro-Classical period (fifth and fourth centuries BCE), which had been preserved under an anthropogenic mound (tumulus) of the 3rd century BCE. Besides stone-work, the construction of the monumental rampart made extensive use of mudbricks. In 2016-2017, PULP introduced a pilot study based on analytical techniques (pXRF, SEM-EDS, granulometric and petrographic analysis) to address issues relating to the manufacture and construction of the earthen architecture of the rampart. The paper presents a description of the geoarchaeological analyses and their results, which have highlighted specific manufacturing practices in relation to the construction of the monument. Given that the rampart constituted a major investment of the royal authorities of ancient Paphos, the results provide new information on the production of earthen building materials and also on environmental choices with respect to raw material selection in the context of a public project carried out by a central authority circa the mid first millennium BCE.

“…As the evaluation of the thermal conductivity of adobe using sludge is scarce, the work of Zhang et al (2016) using lake sediments in the production of ceramic bricks approaches the current study. In their paper, Zhang et al (2016) found a small change in the thermal conductivity from 0.62 to 0.61 W. m ° C-1. In the present study, a small change was observed but the values were statistically the same.…”

Physical, Mechanical and Thermal Behaviour of Adobe Stabilized With the Sludge of Wastewater Treatment Plants

et al. 2019

The need for treated water is essential for life. With the constant increase in population, the most common way to purify surface water is through conventional water treatment plants (WTPs). The high volume of residue (sludge) generated in this process is most often returned to the catchment site, negatively affecting the ecosystem. The sludge of WTPs is similar to soil because it is composed of inorganic solids. Adobe is a construction material made from water and soil without the burning process, so it is considered sustainable, recyclable, and energy-efficient and can be stabilized with various materials. Therefore, the objective of this work is to develop adobes using the sludge of WTPs and to analyse their physical, mechanical and thermal properties. Adobes were produced with five concentrations of sludge by mass: 0, 1, 3, 5 and 7%. It was observed that with the increase in the sludge concentration, there was an increase in the capillarity and a decrease in mass, the water absorption was limited to 3% of sludge, and there was an increase in the bulk density. The linear shrinkage, thermal conductivity and compressive strength were not influenced. The addition of WTP sludge altered some properties of adobe. The use of WTP sludge in adobe is limited to 3%; above that, the adobe becomes unstable in relation to water. Therefore, the use of WTP sludge in the manufacture of adobe is feasible in controlled concentrations and is a sustainable use of the residue.
