“…In these temperature regions, four endothermal signals appeared. The first peak at 100 • C was attributed to the dehydration of calcium silicate hydrates (C-S-H) and ettringite (AFt) [14,21,23,38]. The second peak at 180 • C corresponded to the dehydration of the calcium alumina silicate hydrate (C-A-S-H) [39].…”

“…Indeed, as the GP rate increases, due to its low reactivity, the volume of hydrates responsible for the resistance decreases. From 28 days, it can be noted that the improvement of the strength was due to both the cement hydration and the pores' refinement and densification by the GP particles [21,39,40]. Although, for 10 GP, strengths from 28 days are slightly lower than the control.…”

This study explored the pozzolanic reactivity of granite powder (GP) and its influence on the microstructure of cement paste. An analysis of the physical properties (water demand, setting time, heat of hydration and total shrinkage), compressive strength and durability indicators (water absorption, porosity, acid attack and chloride ions diffusion) was carried out on mortar containing 10%, 15% and 20% of GP as partial substitution to cement (CEM I 42.5 R) in the short and long term. The results showed that the GP does not exhibit pozzolanic reactivity and that it reduces the heat of hydration. Water demand and setting time were not affected by the GP. The compressive strength decreases with increasing the content of GP; but in the long term, the compressive strength was not affected for 10% GP substitution. The presence of granite powder in mortar induces an increase in porosity, which led to an increase in the diffusion properties of fluids (capillary water absorption and chloride ions diffusion).

“…The control mixes were produced with fly ash, which has been successfully used in concrete production for many years. From the observations made during quality control of works and materials used for the national roads in Poland, we knew that the content of fly ash in concretes can reach 50% by weight of cement (on Recent publications [4][5][6][7][8][9][10][11][12][13] indicate an increasing interest in waste glass and its application in concrete production. It is worth noting that use of glass as an addition to concrete can be limited due to the risk of alkali-silica reaction (ASR) [5][6][7]13].…”

“…Other studies have demonstrated pozzolanic properties in concretes containing ground glass [14,16]. There are many research projects [4,7,9,10,17] concerning concrete of C20/25 strength class and higher, in which waste glass is most often seen as a partial substitute for cement, fine aggregate, or both of these ingredients at the same time. On the other hand, there are no studies treating waste glass in the same way as other concrete admixtures, i.e., as a filler and partial substitute for cement.…”

This article presents the results of research on the possibility of replacing fly ash with recycled waste glass in lower-strength concrete mixes. The results of testing concrete mixes containing either waste-glass powder or fly ash are presented in the article. A standard C12/15 concrete mix was chosen for the tests based on its common use for producing concrete for footings to support road kerbs and gutters along national roads in the Polish province of West Pomerania. In the first step of the testing procedure, reference mixes were prepared with 22.5% and 45% fly ash in relation to the content of cement. In the next step, mixes were prepared based on the same specification, except that glass powder was added in place of fly ash. The samples were then tested to determine the influence of waste-glass powder on the main properties of the prepared concrete mixes and on the performance of the concrete when hardened. All the samples were tested for 7 and 28-day compressive strength, water absorption, and freeze-thaw resistance in water. Next, the performance parameters of the samples containing waste-glass powder were compared to the reference mixes containing an equal amount of fly ash. The test results and their analysis allow us to conclude that mixes containing glass powder are not only equal to mixes containing fly ash, but even outperform them by a wide margin in terms of durability.

Milling of granite surface is getting increasingly important in the industry. A major problem is that the effect of granite minerals on surface roughness is currently unknown. The research in this article aims to examine these effects. During the experiment, six surfaces with different cutting speeds were examined on the surface of three different granite samples. The color of the various minerals was determined by light microscopy, and a scanning electron microscope (SEM) and X-ray diffractometer (XRD) were used to analyze the composition of the samples, and a confocal microscope was used to measure the surface roughness of each mineral. From the results of the investigations, we deduced different correlations between the minerals forming granite and the surface roughness. Area-based surface roughness was used in this study because it results more accurate data. From the results, we conclude that the roughness of different surface-forming minerals varies greatly. This causes a high average surface roughness value.
