Obtaining a powder product from brittle materials is associated with significant difficulties: an insufficient number of production capacities as well as with their low efficiency. This indicates relevance and need for research aimed at creating new designs and technological schemes. Glass containers were selected for research from among all types of glass waste. Presented are a structural diagram and description of a horizontal pendulum impact tester, on which studies were carried out on destruction of a bottle by impact load. The impact tester gives an opportunity to determine impact energy, impact speed, acceleration, movement of the impactor. An analysis of the above figures shows that one blow is enough to destroy a bottle. Rational mode is when impact load is distributed along the length of the bottle. This mode can be implemented in a vibratory jaw crusher with an inclined crushing chamber, which includes the following main elements: a passive jaw located on shock absorbers, an active jaw pivotally mounted in the body and connected to it by means of elastic links, a two-shaft inertial vibration exciter. The presented granulometric characteristic of the crushed bottle shows a high efficiency of using a vibratory jaw crusher. The yield of the product sized less than 5.5 mm was 95%, and that sized less than 100 microns - 16%. The crusher has enough parameters to adjust particle size distribution over a wide range.

“…The second region (400 -460 °C) corresponds to the dehydration of portlandite. The third region (550 -830°C) results from the decomposition of calcium carbonate due to the release of CO 2 (16,53,54). Naturally, pastes produced by replacing glass with GMPs exhibit lower amounts of portlandite due to its consumption by the pozzolanic reaction and a lower cement content.…”

This research investigated the influence of using chemically treated glass microparticles as a partial replacement for cement in Portland cement pastes and mortars. The microparticles were obtained by grinding glass waste into three different particle size fractions (< 75 µm, < 45 µm, and < 25 µm), treated with calcium hydroxide (CH), and characterized using SEM/EDS and a laser particle size analyzer. Samples prepared with the incorporation of glass were characterized using XRD, TGA/DTG, and SEM/EDS. The pretreatment with calcium hydroxide induced the formation of C-S-H with different morphologies on the surface of the particles, in addition to causing changes in particle size distribution due to the formation of agglomerates. The pastes prepared with treated particles had lower amounts of CH and higher levels of hydrated silicates. However, when indirectly measuring the pozzolanicity of treated particles through the compressive strength of mortars, no significant differences were observed in the strengths of mortars made with treated and untreated particles.

“…It is well-known that seawater contains high concentrations of aggressive ions, and the related chemical corrosion is thought to be a frequent problem. 7 However, different from the concrete-based wastewater networks, 8,9 insufficient attention has been paid to the effect of MIC on marine concrete degradation, and the importance of protection from MIC is not widely recognized. As corrosive microorganisms can accelerate the corrosion of concrete, 10 the presence of MIC easily results in concrete cracking, which decreases the lifespan of concrete structures 11 and causes considerable economic loss.…”

Biomineralization To Prevent Microbially Induced Corrosion on Concrete for Sustainable Marine Infrastructure

Microbially induced corrosion (MIC) on concrete represents a serious issue impairing the lifespan of coastal/marine infrastructure. However, currently developed concrete corrosion protection strategies have limitations in wide applications. Here, a biomineralization method was proposed to form a biomineralized film on concrete surfaces for corrosion inhibition. Laboratory seawater corrosion experiments were conducted under different conditions [e.g., chemical corrosion (CC), MIC, and biomineralization for corrosion inhibition]. A combination of chemical and mechanical property measurements of concrete (e.g., sulfate concentrations, permeability, mass, and strength) and a genotypic-based investigation of formed concrete biofilms was conducted to evaluate the effectiveness of the biomineralization approach on corrosion inhibition. The results show that MIC resulted in much higher corrosion rates than CC. However, the biomineralization treatment effectively inhibited corrosion because the biomineralized film decreased the total and relative abundance of sulfate-reducing bacteria (SRB) and acted as a protective layer to control the diffusion of sulfate and isolate the concrete from the corrosive SRB communities, which helps extend the lifespan of concrete structures. Moreover, this technique had no negative impact on the native marine microbial communities. Our study contributes to the potential application of biomineralization for corrosion inhibition to achieve long-term sustainability for major marine concrete structures.
