“…Most are in Alaska, but they are across the U.S. as well. Harvesting this material is not damaging to the Earth in the same way that lime mining is, and the process for refining this ash to be useable in concrete does not release the same amount of carbon as Portland cement or burning coal [26,27].…”

Sustainability is a growing area of concern, especially amid the concrete industry. Concrete, especially traditional concrete, which contains Portland cement, is extremely harmful to the environment producing mass amounts of carbon dioxide. Additionally, the harvesting of these materials, like lime, cause significant damage to waterways and the ecosystem. For years, studies have found numerous, more sustainable, alternatives that are structurally equivalent to traditional concrete. The Connecticut Department of Transportation does allow for the use of alternative “green” concretes as long as the mix designs meet the required specifications. Nevertheless, heavy highway construction seems reluctant to dabble with new substances and continues to falls back on the use of fly ash concrete. This solution, however, is not perfect, as fly ash is a finite material. By conducting a nationwide survey to the Departments of Transportation (DOT), the reliance on fly ash was evident. It was also found that the biggest concerns for DOTs would be the cost and availability of the material. This study investigates presently accepted alternative concrete mixture designs and also explores the solutions of volcanic ash concrete and ground glass concrete. Based off the results of the survey and practicality, this study suggests the incorporation of ground glass concrete for heavy highway construction. This solution provides the needed strength requirements per DOT specs and is within the same price-range as fly ash concrete.

“…Many research groups and corporations are dealing with the preparation of concrete from volcanic ash, fly ash, blast furnace slag, silica fume, metakaolin, or pumice, etc. [18][19][20][21]. These research studies have shown that the Portland cement replacement leads to improved material properties of the resulting concrete mixture including diffusive parameters that are involved in durability analysis and, therefore, these mixtures are more suitable.…”

The numerical modelling of chloride penetration into concrete is very sensitive to the correct description of the input data. In the recent era, high-performance concrete (HPC), which combines Portland cement and other supplementary cementitious materials, has been gaining attraction due to their desirable material properties and durability. The presented results show the application of the modified approach for the evaluation of the suitability of the time-dependent model for the variation of the diffusion coefficient. The 26 various binary and ternary-based concrete mixtures blended with volcanic pumice pozzolan (VPP) as a major supplementary cementitious material (SCM) are compared with the reference Ordinary Portland Cement mixture. Other SCMs namely fly ash, slag, silica fume, and metakaolin were also utilized in ternary-based concrete mixtures. In-depth statistical analysis was carried out to show the variability and effects of the amount of the volcanic pumice as an SCM on the diffusion coefficient. The mean value and regression via linear approximation of the time-dependent coefficient of variation of the diffusion coefficients were used as well as the Root of Mean Squared Error approach. The presented results are suitable as the component of the input parameters for the durability-related probabilistic assessment of the reinforced concrete structures exposed to chlorides. In addition, the time-dependent ultimate limit state-related data was presented.

Rhyolite rocks extend from southern Egypt to northern Egypt in the Eastern Desert, and no effective economic exploitation of them has been discovered so far. The pozzolanic activities of different volcanic tuffs (VT) supplied from the Eastern Desert located in Egypt have been investigated as natural volcanic pozzolan materials to develop new green cementitious materials for achieving sustainability goals in the construction field. Experimentally in this paper, the pozzolanic activities of seven diverse specimens of Egyptian tuffs taken with standardized proportions of 75:25% (Cement: volcanic tuffs) were investigated. Pozzolanic features of such tuffs are examined comparatively via strength activity index (SAI), TGA, DTA, and the Frattini’s test. Chemical composition, petrographic, and XRD analysis were also performed for tuffs samples. The pozzolanic reaction degrees were determined according to the compressive strengths at 7, 28, 60 and 90 days with different replacement ratios (20, 25, 30 and 40%) of tuffs samples. Additionally, the micro-filler effects in mortar and concrete were determined by measuring the heat of hydration in mortar samples and the compressive strength of concrete with different additive ratios for tuffs samples besides, the concrete slump test. The results show that TF6 gives a lower cement heat of hydration value which is less than 270 J/g at 7 days. Also, its performance in concrete is better than silica fume at late strength (28 days) since the concrete index value is 106.2% by compared to the concrete index of silica fume 103.9 and therefore it can be used as an alternative to high price and quality variable silica fume (SF) for producing high-performance green concrete. Due to the good pozzolanic behavior proved by nearly most volcanic tuffs, along with their low cost, this study will be profitable for very auspicious the use of Egyptian volcanic tuffs for developing sustainable and eco‑friendly blended cement.
