“…They discovered that initial size of particles of virtually all bioashes used was too large, and that it exceeded the size prescribed for fillers. Similar findings were published by Sargin et al [45] and Xue et al, [46], while Pasandin et al [47] established that the grain size distribution is satisfactory. Consequently, to achieve the desired grading, it is necessary to subject ash to milling and sieving, and to provide for separate storage of individual ash fractions.…”

“…Consequently, to achieve the desired grading, it is necessary to subject ash to milling and sieving, and to provide for separate storage of individual ash fractions. Furthermore, the water content of some biomass ash is higher than permitted [20], [47] and, therefore, attention should be paid to proper storage and transport of ash when it is to be used in asphalt mixtures. Bioash differs by shape of its particles from spherical particles of coal-based fly ash, i.e.…”

“…Bioash differs by shape of its particles from spherical particles of coal-based fly ash, i.e. bioash shape is usually more irregular [20,47,48]. Such particle shape results in higher absorption of bituminous binder and in lower workability of asphalt mixtures [47].…”

“…According to literature data, the ash from rice husk is most often used in hot asphalt mixtures, while other types of ash are either considered inappropriate [47] or their usability has not as yet been explored. Studies have revealed that the use of rice husk ash can increase the Marshall stability and indirect tensile strength in comparison to mixtures with conventional filler [45], [48].…”

Bioashes are inevitable product of meeting the demands to satisfy the increased use of renewable resources in energy production. Ecological and economic problems of bioash disposal, due to its appropriate chemical and physical properties, can be reduced by its application in the construction industry as raw materials. The paper therefore provides an research overview on various aspects of the bioash application in road construction, in compliance with a range of properties depending on the type of biomass and the conditions of combustion. Also shown is current state of research of bioash generated in the domestic thermal power plants.

“…Numerous studies reveal the significant influence of the physical (specific gravity, particle shape, size, texture, size distribution, porosity) and chemical (mineralogy, active clay content) properties of a filler on primary pavement distresses (rutting, fatigue, low-temperature cracking, aging, and moisture susceptibility) [22][23][24][25][26]. Choudhary et al [22] investigated waste materials as fillers in a graded bituminous macadam mix, i.e., copper tailings, carbide lime, brick dust, rice straw ash, red mud, limestone dust, and glass powder which, when mixed with fines, had a superior stiffness and cracking resistance, while mixtures with calcium predominance presented superior adhesion and moisture resistance.…”

Copper mining, the central axis of Chile’s economic development, produces a large number of tailings, which become a potential environmental risk. This study aims to evaluate the mechanical properties resulting from the making of Portland cement mixtures with tailings as aggregates so that they can be eventually used in paving stones for building inactive tailings dams. Tailings coming from two dams at a concentration plant located in Taltal (Chile) were used. Currently, Dam 1 is inactive, while Dam 2 is active. The tailings samples obtained from both dams were granulometrically characterized by sieving. In addition, pH, humidity, Eh, and mineralogical assays (sulfides, oxides, sulfates, carbonates, phosphates, and silicates) were measured. The fines content of the tailings from Dams 1 and 2 with a sieve size of N°200 ASTM were 76.2% and 29.6%, respectively. Therefore, owing to their high percentage of fines, they cannot be as used as concrete aggregates. Aggregates must contain a maximum percentage of fines so that mortars and concrete can meet Chilean standards. In this paper, to comply with a 7% and 15% fines content lower than 0.075 mm, tailings materials were mixed with conventional aggregates containing very little fines. In addition, a reference mixture was made with only tailings aggregates with and without a superplasticizer additive. To measure the mixtures of cement, aggregates, and tailings, bending and compression strength assays were made of the specimens after a 28-day curing, according to the Chilean standard. The results of the study show that the addition of only part of the tailings to the mixture increases bending strength by 26% and compression strength by 180% compared with the reference mortar, with a fines content lower than 0.075 mm in the 7% mixture, thus allowing paving stone manufacture with tailings materials. In addition, it was possible to increase the workability of the reference mixture by using superplasticizers as additives.

Paper production is among the industrial branches generating significant amounts of waste. Organic waste from paper manufacturing is mostly used in gardening and agriculture or converted for energy purposes, while inorganic waste, including green liquor dregs (GLD), is usually deposited on landfills. GLD has a highly alkaline reaction, suggestive of its possible utilization for land reclamation or for improvement of soil's physico‐chemical properties. The research results originate from a pot experiment with maize as the test plant. GLD was added to soil in doses 10–40 t ha−1. The trials consisted of two series: with and without tree bark (TB). GLD contributed to neutralization of the soil's acidic pH, enrichment of the sorption complex with alkaline cations, and to greater salinity of the soil. In the series with TB, it is demonstrated that GLD led to a decrease in the soil content of total organic carbon; while the content of total nitrogen increased, the C:N ratio is considerably narrowed. In response to GLD, the greenness of leaves significantly improves, but this does not translate into an increase in the yield of plants. Regarding the chemical composition of plants grown in soil treated with elevated GLD doses, the content of N and Na is demonstrably higher, although no such effect is discernible in the case of P and K. For the environment, safe doses of the applied waste, not causing significant deterioration of soil properties or depressing crop yields, are 10 and 20 t GLD ha−1.
