application of superabsorbent material is one of the new methods for moisture storage in the soil. this research was performed in the khajeh research station on the basis of randomized complete block design with three replications in the plots with dimension of 4×5 meter for investigate the effect of different amounts of pumice on water retention capacity in the soil, growth and of spring saffl...

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 (...
