“…The initial phase of their production involves mixing only substrates: CaO, SiO 2 , and H 2 O. The mixture is then placed in steel silos resembling reactors (the slaking lime process) [11][12][13][14][15]. The process of slaking is accompanied by an increase in temperature to around 60-80 • C. The standard lime/water ratio is 56 g to 18 g respectively [16].…”

Far-reaching technological progress, manufacturing, and rapidly advancing globalization dictate new conditions for the development and changes in the construction industry. Valorization of by-products and the use of secondary materials in the production of building materials have attracted a lot of attention. Silicate materials were assessed on the basis of their compressive property. An orthogonal compositional plan type 3k (with k = 2), that is, a full two-factor experiment was applied in order to carry out the compressive strength and bulk density tests. Glass sand was added to the silicate mass as a modification. The results show that the compressive strength was higher than that of traditional bricks. Scanning electron microscopy coupled with energy dispersive spectrometry SEM/EDS was used to study the microstructure, whereas the XRD analysis was applied to examine the structures. Laboratory tests were performed on samples with dimensions of 50 × 50 × 50 mm. The results show the bulk density increase to the value of 1.75 kg/dm3, which increases the acoustic performance of the new products. The results of the modifications also indicate changes in the structure of the new bricks. The reference sample contained α-quartz, zeolite, tobermorite 9A, and calcium aluminum silicate (Ca2Al4Si12O32), whereas the samples modified with glass sand, the presence of phases such as α-cristobalite, natrolite, tobermorite 11A, gyrolite, and analcite was recorded.

“…Research on the modi cations subject and the reduction of compressive strength of lime-sand bricks is more and more often encountered [5][6][7]. The modi cation itself of lime-sand products with recycled glass in various forms [8][9][10][11], as well as modi cation with waste materials [12][13][14][15] is already known in literature and practice. The foamed glass granulates were also tested as an addition to cement mortar [12], and how it contributs to the reduction of density and compressive strength of the product.…”

Silicate products are products made exclusively from natural raw materials. A relatively high value of the heat transfer coefficient is still considered a fault. This property adversely affects the thermal insulation of buildings and energy consumption, so you should look for materials with a low heat conduction coefficient. One of the ways of obtaining such products can be the use of light, porous fillers in the mass of lime-sand products.Due to the above, particular attention was paid to white foam glass in the form of granules, which is a product of recycling glass cullet. The research was carried out with a granulate size of 0.25-0.5 mm, share of which in the tested samples ranged from 5 to 30%. The obtained results were referred to the tests carried out on basic (lime-sand) sample.The aim of the article is to determine the correctness of the formation of selected usable properties of modified lime-sand products, taking into account changes in their microstructure. The article describes the results of volume density and compressive strength tests of basic samples and the samples modified by using the expanded glass granulate as well as the results of their observations by using of SEM and tests of phase composition obtained from XRD.

“…One such solution is the possibility of using sand with recycled glass in the production of silicate. Analyzing the scientific literature on the results of already conducted research into the impact of glass components in autoclaved materials, it can be concluded that the topic deserves further exploration (Stępień et al, 2019a;Stępień et al, 2019b;Stępień et al, 2020). Glass recycling produces many composites, the most popular being: glass sand, glass powder or glass fibers.…”

The use of recycled glass sand in building materials requires the assessment of its strength and thermodynamic properties. The paper presents the results of research on the influence of glass sand on the structure and properties of silicate brick and the composition of the material modified by introducing a glass composite. The structure of the sand-lime material was assessed on the basis of scanning electron microscopy analyzes using the SEM QUANTA FEG 250 microscope. From the obtained results, it was found that glass sand had a positive effect on the compressive strength, keeping the material at a level not exceeding 20 MPa. Research based on SEM shows that the modification with glass sand leads to the crystallization of the C-S-H phase towards gyrolite and natrolite in the modified brick and tobermorite in the reference brick. Silicates, as natural materials, fit into the criteria of ecological construction and due to this fact, the work has relevance on the subject of sustainable construction.
