Multiphase lightweight aggregate concrete (MLAC) is a green composite building material prepared by replacing part of the crushed stone in with other coarse aggregates to save construction ore resources. For best MLAC performance this paper, four kinds aggregate—coal gangue ceramsite, fly ash pumice and coral—were used different dosages (10%, 20%, 30% 40%) total replacement. Mechanical property...

Metal contamination is one of the most serious global problems. This investigation deals with use Aksaray pumice for adsorption cobalt ions. The factors affecting on were examined. Pumice activated at 873 K two hours before contact UV-Vis spectrophotometer was used to measure ions concentrations. response surface methodology utilized evolve predictive model pumice. experimental and predicted ma...

In this research, the effect of the cement, sand, and pumice mixture on the durability of lightweight concrete is investigated. The intention of this paper is to replace a certain amount of the pumice percentage as an alternative option of the cement and pumice sand aggregate with conventional sand components. The experimental results include compressive strength, ion-chloride emission factor (...

Artificial live rock is an artificial that shaped like living in nature. designed to mimic natural which capable of being a substrate for corals, habitat epibenthic and the biological filter saltwater aquarium. The purpose this research know technique making development are suitable export on scale. method used experimental with quantitative descriptive analysis. level suitability product stand...

Domestication and taming. Archaeozoologists generally use the word domestication when they have good evidence for morphological modifications such as the decrease of the general size or the shortening of the face and tooth raw. However, morphological modifications may not appear for some considerable time after the original association with man. We use the term 'taming' for the early history of...
