“…We recorded a rate of 71 % with the presence of sulphate. Most studies have shown that the flexural strength only increased at the optimum content of the additions, after which the flexural strength decreased again when the fiber content increased further [49]. Moreover, we found that cement to the adobe increased the thermal conductivity by a significant percentage.…”

Adobe constructions have always existed, particularly in the Sahara’s dry and scorching regions. This material has a high thermal inertia and can protect buildings from inclement weather. Its mechanical resistance, on the other hand, is still low and has to be increased. The current research, thus, investigated the effect of sand salinity on the thermal and mechanical properties of adobe. The sand needed to create adobe blocks was purchased from 2 distinct locations. The first one was normal sand while the other one was salty sand rich in SO4- sulfate. We considered different ratios of each sand from 10, 20 up to 90 %. The results showed that the adobe made from the sulfate-containing sand improved the compressive strength by about 36 % from 1.91 to 2.58 MPa, and flexural strength by about 71 %, from 0.35 to 0.60 MPa, and reduced the thermal conductivity by 14 % from 0.86 to 0.72 w/mk. HIGHLIGHTS Improving the compressive strength by about 36 % Improving the flexural strength by about 71 % Improving its thermal behaviour and inertia by about 3 % Testing more of 90 samples Studying two different locations Analyse Mineral and physical Analyse of clay and sands from the arid zone GRAPHICAL ABSTRACT

“…-Gruntui sutvirtinti. Teigiama, kad pridedant nedidelius kiekius PTP atliekų į molinguosius ir smėlinguosius gruntus, įvairios mechaninės jėgos padidėja (Abbaspour et al, 2019;Narani et al, 2020;Zare et al, 2020); -Betono gamyboje. Atliekant tyrimus buvo nustatyta, kad PTP atliekos nepagerina mechaninių betono savybių, bet sumažina gaminio šiluminį laidumą (Malaiškienė et al, 2015;Baričević et al, 2018).…”

Perdirbant padangas, gumos granulės ir metalo pluoštas sėkmingai naudojami pakartotinai, tačiau padangų tekstilės pluošto (PTP) atliekos yra gana didelė problema. Mokslininkai vykdo tyrimus, bandydami šias padangų tekstilės pluošto atliekas, naudoti šiluminei izoliacijai, nes čia matomas didelis jų potencialas. Kadangi šiluminė izoliacija turi artimą ryšį su garso sugertimi, manoma, kad PTP sėkmingai tiktų panaudoti ir triukšmui patalpose mažinti. Tyrimo metodas remiasi ISO 10534-2 standartu, kuriuo būtų nustatytas medžiagos garso sugerties koeficientas α naudojant impedanso vamzdį. Tyrimo metu gauti rezultatai parodė, kad PTP atliekos turi geras garso sugerties savybes, garso sugerties koeficientas, esant žemiems dažniams 250–500 Hz, buvo 0,06–0,52, o esant aukštesniems dažniams – 1000–1600 Hz, sugerties koeficientas varijavo tarp 0,44–0,94. Šios medžiagos naudojimas būtų puiki alternatyva šiuo metu naudojamoms tradicinėms mineralinėms pluoštinėms medžiagoms.

“…Thus, we are increasingly observing the establishment of housing made of modern materials in rural villages/ towns, although since the 1970s, many researchers, with the aim of promoting the use of eco materials in buildings modern, examine the issue of substitution of sea sands, gravel/crushed and steel, respectively by laterite/lagoon sand, laterite nodule [1][2][3][4][5][6][7][8][9][10][11], rice husks [12][13][14][15] and certain woody forest products [16][17][18][19][20][21][22][23][24]. Other researchers have used waste materials to improve the mechanical properties of rammed earth structures [25][26][27][28][29].…”

This work enrolls in the context of eco materials. It concerns the field of transformation of local shrub forest resources and lateritic earth with low market values into building materials and is developing a process for the valorization of lateritic nodules, Borassus aethiopum (palmyra) and Calamus deerratus (rattan) in the engineering of modern reinforced concrete structures. The objective of this process is to promote the rational use of these local materials in the realization of the floors of social housing. Experimental studies of physical and mechanical characterizations of the lateritic concrete formulated, of the palmyra and rattan woods were carried out. Through tests of tearing and sliding of the interface between normal concrete and laterite concrete (push-out tests), it has been highlighted the adhesion of palmyra wood to concrete and the contribution of rattan lianas to oppose the longitudinal sliding of the interface between two concretes of different nature. The case study of a hollow body slab in mixed concrete (normal and laterite concrete) reinforced with palmyra and rattan woods, showed the structural effectiveness of lateritic earth, of palmyra and rattan woods in the realization of social housing modern slads with a range of up to 5 meters.
