Characteristics of Self-compacting Concrete Incorporating Palm Kernel Shell Ash with Variations in Superplasticiser Content | Chapter 7 | Engineering Research: Perspectives on Recent Advances Vol. 11

 

The low water-to-cement ratio in Self-Compacting Concrete (SCC) aims to increase the compressive strength of concrete, but the lower amount of water results in lower workability. Thus, it is necessary to use chemical additives of superplasticiser (SP). SP improves workability while maintaining the specified water-to-cement ratio. This study aims to determine the characteristics of SCC incorporating palm kernel shell ash (PKSA) with varying SP content. The SP content in SCC was 1.5%, 2.0%, and 2.5% of the concrete total mass. The PKSA was 0% and 10% of the total binder mass, and the water to cement ratio was 0.35. The SCC was designed as a C30 class. Some tests of fresh and hardened SCC produced characteristic data that included flowability, viscosity, passing ability, density, and compressive strength. Fresh concrete tests were the slump flow, V-funnel, and L-box tests. There were six SCC mixtures, each with five hardened cylindrical samples for density and compressive strength tests. The addition of SP content increased the flow distribution diameter, decreased viscosity, and increased passing ability. PKSA, as a partial replacement for cement, reduced the density of SCC and increased the compressive strength, but not significantly. The highest compressive strength was obtained in SCC with 10% PKSA and 1.5% SP of 34.75 MPa at the age of 28 days. The use of SP by more than 1.5% increased workability but reduced the compressive strength of SCC by inhibiting the binding process.

Plant Leaf Ash Adsorbent for the Treatment of Greywater | Chapter 15 | Innovations in Biological Science Vol. 1

 Plants are very useful every time in an environment. Greywater generation is not in the control of humans, but the treatment of greywater is in our hands. This study was based on greywater treatment and minimizing its impact using the ash of plant leaves of tulsi (Ocimum tenuiflorum) and subabul (Leucaena leucocephala) as eco-friendly tactics towards sustainable greywater management. This study focused on using plant leaves as adsorbents to minimize unwanted substances in grey water. The leaves of plants can burn at high temperatures in a controlled environment to obtain ash, which is used to minimize and remove pollutants like nutrients, organic compounds, and impurities, from grey water. The study aims to investigate the efficiency of plant leaf ash as an adsorbent, and the potential of the plant leaf for grey water treatment. The study could have significant implications for the development of low-cost and eco-friendly greywater treatment technologies. The use of plant leaf ash for greywater treatment could provide a sustainable and natural alternative to conventional greywater treatment methods. It will minimize the biochemical oxygen demand, chemical oxygen demand, organic matter load, and NPK also at a certain level and it helps to minimize the toxicity of greywater. The results showed that plant leaf ashes were effective in reducing the levels of pollutants.

An Overview of the Research and Application of Various Activated Carbons and Ash Used in Water Purification Technology | Chapter 7 | Emerging Issues in Environment, Geography and Earth Science Vol. 1

 Water is an essential aptitude that nature gives to all living individual. In order to keep all history safe on soil, it is necessary to keep the amount of water in the corpse adequate and enough at all times. Water pollution is growing as a result of differing factors such as study of human population, large-scale urbanization, clear-cutting, and unfair activities in waterways and other water beginnings. Various experts have worked on the result of activated element from renewable energy. This comprises economical technology and merchandise in an eco-friendly way for a assortment of uses. This review article discusses the differing methods secondhand by experts to develop triggered carbon so that minimize water pollution. Peanut coverings, Moringa oleifera seeds, Coconut structures, Rice husk, Lemon peel, Pomegranate peel and Banana peel are all excellent natural resources for treating poisoned water. It was demonstrated that pollutants to a degree pH, colour, DO, conductivity, turbidity, chloride, fluoride, TSS, TDS, BOD, COD, nitrate, phosphate, burdensome metals, and total coliforms can be isolated from water utilizing physical, machinelike, and biological techniques.

Carcass Characteristics of Commercial Broiler Chicks Affected by Probiotic Supplementation | Chapter 4 | Research Aspects in Agriculture and Veterinary Science Vol. 3

 The goal of this study was to see how probiotics affected the carcass characteristics of commercial broiler chicks. The study looked at two probiotic levels (without and with probiotic supplementation). The probiotic groups had two replicates in the trial. At the 6th week of age, the carcass characteristics and conformation traits of broilers were assessed. The data was evaluated based on the number of survivors and the number of birds in each subclass. Because the differences between replicates for the different variables under research were not significant after analysis of variance, all following analysis was done on a combined sex basis. The results of the current investigation on percent shrinkage, percent dressing, percent giblet, and total percent meat yield revealed a substantial influence on males, females, and combined sex basis when probiotics were included. Most carcass components in the control group had a higher percent yield than those in the probiotic-supplemented diet. The cut-up components yield (leg, breast, back with neck, and wings) were almost identical in the control and probiotic supplemented dietary groups, and the percentage was likewise lower in the probiotic supplemented food group than in the control group. The treatments had no influence on the moisture, fat, or ash content of the meat, according to the proximate principles of the meat. The protein content of broiler diets containing Probiotics, on the other hand, was dramatically lowered. Lactobacillus counts were greater in the probiotic-fed groups than in the control group.
