Water scarcity is an important obstacle to the development and expansion of urban landscape in the arid and semi-arid regions of the world. Nowadays organic and artificial materials can be used to reducing water consumption without reducing the quality and quantity of urban landscape. In order to study of the effect of some mulch type on the reduce of irrigation interval on a popular seasonal p...

In this study, we analyzed the strength and shrinkage properties of concrete with three additives, superabsorbent polymer (SAP), calcium sulfoaluminate (CSA) clinker, shrinkage-reducing admixture (SRA), to verify internal curing reduction effects. According compressive tests, use SAP as an additive resulted in a slight decrease strength, whereas using 10% CSA clinker 8 MPa higher than that ordi...

A capacitive electrocardiography (cECG) technique using a non-invasive ECG measuring technology that does not require direct contact between the sensor and the skin has attracted much interest. The system encounters several challenges when the sensor electrode and subject's skin are weakly coupled. Because there is no direct physical contact between the subject and any grounding point, there is...

Polyurethanes with water expansion properties are manufactured by incorporating polyurethane resins and superabsorbent polymers. This study aimed to present an optimal mixing ratio of a polymer that can express the effective waterproofing performance material properties. The evaluation results confirmed was exerted at more than 10% 150% or more, which were then set as minimum standard value for...

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...
