“…Similar effects were obtained using oils from sunflower, peanuts, and rapeseeds [27]. The addition of spent cooking oils in the lime mortars produced a significant hydrophobic effect, diminishing capillary water transport [26].…”

“…In historic, vernacular architecture, for example, there are references to the use of organic components improving the mechanical properties, workability, and waterproofing of natural mortars [6,12,15]. Some of them have been recently rediscovered and investigated [18], including, among others, sheep wool [9,19], animal glue [20], casein [20][21][22], eggs [21], olive oil [20], linseed oil [22][23][24][25], sunflower oil [26,27], straw [14,[28][29][30], and hemp [31,32].…”

“…The adverse consequences of such modification may be slower development and lower value of mechanical strength, as described in [23,25]. In some cases, however, the addition of fatty acids to the lime mortars significantly increased their hydrophobicity without worsening mechanical strength [20,26].…”

Raw clay is used nowadays in construction as a component of mortars and plasters and as a binder in composites based on straw or shives. It is a material with good sorption properties and vapor permeability, but it is susceptible to shrinkage, is not resistant to water, and also is characterized by low mechanical strength, which makes it impossible to be used, for example, in external plasters. Various additives and admixtures are used to improve selected properties of clay mortars. The article presents the research results and assessment of the effect of glauconite clay mortar modification with an admixture of linseed oil varnish on selected properties. Admixtures in the amounts of 1%, 2%, and 3% in relation to clay weight were used. Flexural and compressive strength, water resistance, shrinkage, drying capacity, density, and porosity of mortar, were tested. The admixture of linseed oil varnish in the amounts used in the investigation had a positive effect on some of the tested properties; regardless of the quantity of the admixture, the modified mortars had better parameters concerning flexural strength, shrinkage reduction, and water resistance than the reference mortar, without admixture.

“…In order to reduce CO 2 emissions in the life cycle of mortars/concretes, several approaches [7][8][9][10] have been suggested, such as replacing virgin materials with industrial by-products [11][12][13][14], improving durability in order to reduce maintenance costs [15], and increasing the use of low-CO 2 Portland cements and the development of alternative low-CO 2 binders. As an example, low-CO 2 cements can be produced by using non-carbonated CaO sources as a constituent of the Portland clinker-generating raw mix [16,17] or increasing the production of blended cements, obtained by mixing Portland clinker with…”

Calcium Sulfoaluminate, Geopolymeric, and Cementitious Mortars for Structural Applications

et al. 2017

This paper deals with the study of calcium sulfoaluminate (CSA) and geopolymeric (GEO) binders as alternatives to ordinary Portland cement (OPC) for the production of more environmentally-friendly construction materials. For this reason, three types of mortar with the same mechanical strength class (R3 ≥ 25 MPa, according to EN 1504-3) were tested and compared; they were based on CSA cement, an alkaline activated coal fly ash, and OPC. Firstly, binder pastes were prepared and their hydration was studied by means of X-ray diffraction (XRD) and differential thermal-thermogravimetric (DT-TG) analyses. Afterwards, mortars were compared in terms of workability, dynamic modulus of elasticity, adhesion to red clay bricks, free and restrained drying shrinkage, water vapor permeability, capillary water absorption, and resistance to sulfate attack. DT-TG and XRD analyses evidenced the main reactive phases of the investigated binders involved in the hydration reactions. Moreover, the sulfoaluminate mortar showed the smallest free shrinkage and the highest restrained shrinkage, mainly due to its high dynamic modulus of elasticity. The pore size distribution of geopolymeric mortar was responsible for the lowest capillary water absorption at short times and for the highest permeability to water vapor and the greatest resistance to sulfate attack.

LPW can be used in composites with two different types of spent sun ower cooking oils and brick waste powder as pozzolanic addition of new lime mortars (Pahlavan, et al, 2017) or glass mortars (Yang, Poon, Ling, 2019); to produce cementless controlled low-strength material based on waste glass powder (Xiao, et al, 2021); for soil stabilization based on recycled-glass powder waste and dolomitic lime (Baldovino, et al, 2021); for preparation of geopolymer (El-Naggar, et al, 2019); as amendment of municipal sewage sludge with lime and mussel shell (Wang, et al, 2019) or for production of lime-incineration sewage sludge ash pastes (Zhou, et al, 2021); for cementless controlled low-strength material based on waste glass powder (Xiao, et al, 2021).

To prevent environment pollution by hazardous industrial dumps of iron ore treatment sludge, concrete production/demolition debris and lime production waste sustainable cement-less construction materials were developed for substitution of traditional natural raw components excavated in careers, irreversibly destroying natural bonds. Their axial resistance values on the 3rd day of hydration were till 2.34 MPa, on the 28th day - up to 3.94 MPa, on the 180th day 8.40 MPa and on the 365th day 10.22 MPa. The expanding coefficient on the 3rd day were till 2.13%, 2.51% on the 28th day, and on the 365th day 2.22%. Water absorption on the 28th day was 7.17 - 9.32% and decreases to 6.26 - 8.64% on the 90th day. All these characteristics correspond to the Brazilian norms. The physical - chemical processes of materials’ structures formation included alkaline dissociation of solid particles’ surface, with sol appearing and densification till transition to gel. Long-lasting gel compaction and densification to stone-like condition made its structure similar to natural rock materials - silica, opal, obsidian, perlite, pumice, amber, flask, etc. They can be used for production of road bases, concrete blocks and solid unburned bricks, among other sustainable construction materials.
