The acquisition and transportation of aggregate exacerbate the negative impact of concrete on the environment, and waste materials are considered an effective solution to this crucial problem. One of these waste materials is waste ballast (WB), which is needed for new infrastructure along with increasing rail track technology. In this study, the effect of WB aggregate (which is basalt-based) on the mechanical and durability properties of standard concrete was examined. Coarse aggregate was replaced with WB aggregate at the rates of 50%, 75% and 100%. The slump, compressive strength, flexural strength, capillary water absorption, rapid chloride permeability and water penetration tests on the mixtures were performed. According to the results of this study, the utilization of WB improved the compressive strength and flexural strength of the mixtures by about 15% and 7%, respectively. Moreover, the capillary water absorption, rapid chloride permeability and water penetration values of all the concrete mixtures with WB were lower than the control mixture. In addition, the correlation relations between the mechanical and durability properties indicated that they have a strong relationship with each other. All the results of this study demonstrated that the utilization of WB instead of coarse aggregate improved the mechanical and durability properties of concrete. WB can also provide a more sustainable material formation by minimizing the negative environmental effects of concrete production.

“…Concrete is the most used and essential construction material after water all over the world (Güneyisi et al, 2014;Umar et al, 2021;Mermerdaş et al, 2021). Most concrete structures undergo a variety of durability problems within their service of life (Yücel et al, 2020;Kurtoğlu et al, 2018). One of the most important parameters of concrete in the aspect of durability is permeability.…”

Most concrete structures undergo severe durability issues throughout their service of life. The transition and movement of water through concrete structures is one of the main issues in the aspect of durability. The main aim of this study is to investigate the effect of cement replacement in various ratios with eggshell powder on the sorptivity (capillarity water absorption) capacity of concrete. Eggshell is a bio-waste material obtained from bakers, restaurants, and patisseries. Disposing of this waste material in landfills results in health hazards and causes environmental pollution. The use of eggshell powder in concrete, which is the most used and essential building material after water all over the world, is a beneficial way both minimize the detrimental effects of this waste on living health and the environment and also ensure the sustainability of the materials in concrete. In this paper, five different eggshell powder substitutions as 0%, 5%, 10%, 15%, 20% were employed in experimental analyses. The sorptivity index of concretes was measured at the end of each 5, 10, 15, 30, 45, and 60 minutes. The test results indicated that the sorptivity namely capillary water absorption decreased with up to a level of 5% replacement and increased with the other replacement ratios including 10%, 15%, and 20% when compared with the control concrete’s result. This is attributed to the ESP may act as a better inert filler when replaced with cement up to a level of 5% to reduce the capillary pore, increase the compactness of concrete microstructure, impermeability and restrain the transition of water in the concrete structure.

This study evaluated the possibilities of pumice (light stones) as litter material in broiler production. Experimental treatments included wood shavings (WS), acidic pumice (AP), and basic pumice (BP) alone, and in combination; wood shaving + acidic pumice (WSAP) and wood shaving + basic pumice (WSBP) in a ratio of 1:1. Two trials were performed, one in summer, and the other in winter. Each trial involved 750 mixed-sex Ross (308) broilers. Also, there were 15 replicate pens with 50 broilers and a stocking density of 12.5 birds/m2 for each pen at the beginning of each trial. Performance, litter quality, carcass parameters, body and leg abnormalities, body temperature, fear and stress responses, proportional asymmetry, and some behavior expressions were investigated. The litter treatment influenced the final live body weight, litter moisture, ammonia concentration, footpad dermatitis, hock burn, breast blister, hot carcass yield, heart, liver, spleen, abdominal fat, wing and neck ratio, breast and back cleanliness, and the expression of dust bathing and foraging behaviors (P < 0.01; P < 0.05). Furthermore, there was a seasonal effect on live body weight, feed conversion ratio, livability, litter pH, 42-day litter moisture, hot carcass yield, back cleanliness, footpad dermatitis, hock burn, footpad temperature, heterophil-to-lymphocyte ratio, and expression of pecking behavior (P < 0.01; P < 0.05). It is suggested that acidic pumice stone alone or in a mixture with wood shavings could be used as a reliable litter material, alternative to wood shavings.
