“…One of the materials that can be used as a partial substitute for cement in concrete mixtures is glass powder. Glass powder was chosen because the main constituent material is silica (SiO2), a pozzolanic material whose use can increase the compressive strength of concrete [8][9][10][11], [13][14][15]. Previous researchers have argued that the best use of glass in concrete is by grinding it into finer grains, because the fine particles in the glass powder can fill the air voids in the concrete to reduce the number of fine cracks, which eventually can increase the compressive strength of concrete [16][17][18][19][20].…”

Excessive use of cement can cause damage to the environment. Using materials that have similar properties to cement as a concrete mixture can reduce the use of cement. Because the silica content in glass is quite large, glass has the potential to be used as a partial substitute for cement in concrete. This study aims to determine the effect of glass powder used as a partial cement substitute on the compressive strength of normal concrete. This study uses cylindrical specimens with 15 cm in diameter and 30 cm in height according to SNI 03-2834-2002. They were tested at seventh, fourteenth, and twenty-eighth day. The variations of the glass powder are 0%, 4%, 8%, 12%, and 16%. Based on the results of the testing at the twenty eighth days, the concrete's compressive strength at 0% variation is 22.8 MPa, at 4% variation is 24.0 MPa, at 8% variation is 17.5 MPa, at 12% variation is 17.6 MPa, and at 16% variation is 7.9 MPa. Thus, using glass powder as a partial substitute for cement in concrete mixtures affects the compressive strength of normal concrete. At the twenty-eighth day, the compressive strength of the concrete has increased by 5% to 24.0 MPa.

“…The total production of fly ash and silica fume in the Ningxia region in 2021 reached 1800 × 10 4 t. Its considerable accumulation not only occupies land but also causes severe environmental pollution, so the question of how to obtain value from waste and realize resource utilization is a problem worth studying. Research showed that the active substances SiO 2 , Al 2 O 3 , etc., in fly ash and silica fume can be used as a mineral admixture to promote the cement hydration reaction [ 4 , 5 , 6 ], which can save resources when mixed into cement slurry—for example, the use of fly ash can reduce the required cement dosage by 50% [ 7 ]. Adding fly ash and silica fume into foamed concrete represents the resource utilization of fly ash and silica fume, realizing the concept of obtaining value from waste, and realizing the requirements of environmental protection.…”

Although fly ash foam concrete (FAFC) is lightweight, heat-retaining, and insulating, its application options are constrained by its weak construction and short lifespan. The effects of various dosage ratios of the foaming agent (i.e., hydrogen peroxide), silica fume, and polypropylene fiber on the dry density, compressive strength, thermal insulation performance, pore structure parameters, and durability of FAFC were analyzed in this study, which sought to address the issues of low strength and low durability of FAFC. According to the findings, there is a negative correlation between the amount of hydrogen peroxide (as the foaming agent) and compressive strength, and, as the silica fume and polypropylene fiber (PP fiber) content rise, the strength will initially rise and then fall. The distribution of pore sizes gradually shifts from being dominated by small pores to large pores as the amount of foaming agent increases, while the porosity and average pore size gradually decrease. When the hydrogen peroxide content is 5%, the pore shape factor is at its lowest. The pore size distribution was first dominated by a small pore size and thereafter by a large pore size when the silica fume and PP fiber concentration increased. Prior to increasing, the porosity, average pore size, and pore shape factor all decreased. Additionally, the impact of PP fiber on the freeze–thaw damage to FAFC was also investigated at the same time. The findings indicate that the freeze–thaw failure of FAFC is essentially frost heave failure of the pore wall. The use of PP fiber is crucial for enhancing FAFC’s ability to withstand frost. The best frost resistance is achieved at 0.4% PP fiber content. In conclusion, the ideal ratio for overall performance was found to be 5% hydrogen peroxide content, 4% silica fume content, and 0.1% polypropylene fiber content. The results obtained could be applied in different fields, such as construction and sustainable materials, among others.

“…The 4% SF increased the compressive strength of BCB by 27.55%, while the 4% FA increased the compressive strength by 17.36%. Sherong Zhang [ 24 ] combined SF with waste marble powder (WMP) and found that cellular concrete containing 10% SF and 5–20% WMP showed the best mechanical and durability properties. Mojtaba Nili [ 25 ] used concrete mixed with air and silica fume to show the best performance in salt scale tests, the addition of SF reduced the total pore volume and refined the pore distribution.…”

In this study, the rheology, fluidity, stability, and time-varying properties of cement paste with different substitute contents of silica fume (SF) were investigated. The result showed that the effects of SF on macro-fluidity and micro-rheological properties were different under different water–cement ratios. The addition of SF increased the yield stress and plastic viscosity in the range of 2.61–18.44% and 6.66–24.66%, respectively, and reduced the flow expansion in the range of 4.15–18.91%. The effect of SF on cement paste gradually lost its regularity as the w/c ratio increased. The SF can effectively improve the stability of cement paste, and the reduction range of bleeding rate was 0.25–4.3% under different water–cement ratios. The mathematical models of rheological parameters, flow expansion, and time followed the following equations: τ(t) = τ0 + k0t, η(t) = η0eat, and L(t) = L0 − k1t, L(t) = L0 − k1t − a1t2. The SF slowly increased the rheological parameters in the initial time period and reduced the degree of fluidity attenuation, but the effect was significantly enhanced after entering the accelerated hydration period. The mechanism of the above results was that SF mainly affected the fluidity and rheology of the paste through the effect of water film thickness. The small density of SF particles resulted in a low sedimentation rate in the initial suspended paste, which effectively alleviated the internal particle agglomeration effect and enhanced stability. The SF had a dilution effect and nucleation effect during hydration acceleration, and the increase of hydration products effectively increased the plastic viscosity.
