The influences of liquid-binder ratio and mixing sequence on the performance superabsorbent polymer (SAP)-containing alkali-activated slag (AAS) mortar are investigated in this study. It is found that SAP absorbs much less liquid upper supernatant AAS than water. Mixing with first induces a larger absorption capacity it solid first. Increasing improves flowability but reduces strength SAP. None...

Water sources optimizing required a suitable irrigation program. Different material can use to increase water use efficiency. Superabsorbent is one of the materials where used in around the world. These materials put in the soil and absorb water so that reserved water is usable by plant in the time of drought stress and they can reduce stress and lead to prevent yield loss. Therefore, the exper...

The preparation of an itaconic acid-based oligomer and its polymerization with acrylic acid via aqueous solution copolymerization are described herein for application as novel superabsorbent polymers (SAPs). structure the SAP is characterized using Fourier transform infrared (FT-IR) spectroscopy. In addition, absorption properties SAPs various contents degrees monomer neutralization evaluated b...

A solution polymerization method has been used to synthesize a polyacrylic-type superabsorbent polymer (SAP). The influence of various influential factors, such as the temperature, neutralization degree, cross-linking agent, and initiator, on water absorption capacity SAP investigated. results show that can display non-monotonic behavior depending synthesis conditions. also change according pH,...

The consumption of diapers and sanitary products has constantly been rising. Several problems are associated with using chemical-based products, which difficult to degrade easily cause nappy rash bacterial infections in babies. Therefore, there is an increasing shift towards natural-based because their biodegradability, non-toxicity, biocompatibility. studies being carried out researchers have ...

Introducing superabsorbent polymer (SAP) into white fair-faced concrete can achieve the purpose of internal curing, which is beneficial to popularization and application concrete. The effects SAP mixture curing water content on properties were investigated macroscopically through indexes, including slump, electric flux, standard cube compressive strength, tensile splitting strength. mechanism t...

Superabsorbent polymer (SAP)-containing wound dressings present a valuable and unique category of wound management products. An in vitro approach was used to assess the effects of a new SAP dressing in treatment of non-healing wounds. It was shown that the SAP dressing possesses a significant binding capacity for MMP-2 and MMP-9 in vitro (P\0.001). The inclusion of the bound proteases was so st...
