The article presents an analysis of the results experimental studies effect different types a super absorbent polymer additive on strength concrete. study is aimed at effectiveness new type in concrete structures. In course full-scale experiments, it was possible to identify optimum dosage SAP for fine-grained and heavy concretes. addition, showed that remains unchanged if (SAP) 0.5% weight cem...

We consider the multidirectional swelling and drying of hydrogels formed from super-absorbent polymers water, focusing on elastic deformation caused by differential swelling. By modelling as instantaneously incompressible, linear-elastic materials considering situations in which there can be large isotropic strains (arising swelling) while deviatoric remain small, it is possible to describe acc...

Natural strategies for protecting the environment as well plant, animal and human health is considered one of main goals developed countries. Recently, use absorbent polymers hydrogel in agriculture has demonstrated several benefits soil amendments, saving water content, reducing consumption nutrients, minimizing negative impacts dehydration moisture stress crops controlling phytopathogens. The...

Abstract Super absorbent polymer is a new type of functional material that has been researched in recent decades. Due to its special structure and water-absorbing water-retaining properties, it broad field drought resistance, soil improvement crop protection. It conditioner agricultural drought-resistant water-saving materials. Combining with fertilizers prepare forestry slow-release functions,...

AIM The aim of this paper is to report a study to determine the effects of absorbent pads on the pressure-relieving properties of 'standard' and pressure management mattresses. BACKGROUND Pressure ulcers and incontinence often co-exist. There is a strong association between poor mobility and continence problems and patients using pressure management products are therefore also likely to be us...
