This study focuses on the effect of the amount of silica fume addition and volume fraction of steel fiber on the engineering properties of cementitious materials. Test variables include dosage of silica fume (5% and 10%), water/cement ratio (0.35 and 0.55) and steel fiber dosage (0.5%, 1.0% and 2.0%). The experimental results included: compressive strength, direct tensile strength, splitting te...

Fiber type distributions, cross-sectional areas (CSAs) and succinate dehydrogenase (SDH) activities in the soleus (SOL) muscle in normotensive Wistar-Kyoto (WKY) and spontaneously hypertensive (SHR) rats were determined after exposure to cigarette smoke at three different dosage levels using a smoking machine. The rats were exposed to cigarette smoke at a rate of 15 puffs/min, for 20 min/day wi...

To explore the law of microwave deicing carbon-fiber-modified concrete under action multiple factors and improve its application in pavement, this study, we designed a test heat absorption effect factors. We found that CFRP is influenced by coupling fiber length dosage, height (straight-line distance between receiving surface bell component), initial temperature ice cover. The rises fastest whe...

The mechanical properties of polymer impregnated concrete containing polypropylene fiber were statistically and experimentally examined in this study. Taguchi L9 (33) was used variables for experiments selected as the ratio (0%, 1% 2%), cement dosage (300, 350 400 kg/m3) curing time (7, 14 28 days). After specimens cured at specified times, they dried 105 ±5 °C. Then, monomer to 24 hours under ...

The design, preparation and application of three-dimensional (3D) printed structures have gained appreciable interest in recent times, particularly for drug dosage development. In this study, the electrohydrodynamic (EHD) printing technique was developed to fabricate aligned-fiber antibiotic (tetracycline hydrochloride, TE-HCL) patches using polycaprolactone (PCL), polyvinyl pyrrolidone (PVP) a...

expansive soils undergo volumetric changes in response to changes in their moisture content that this characteristic causes irreparable problems particularly in civil projects. investigators have proposed chemical methods as well as mechanical treatments to stabilize the expansive soils. in this study, stabilization of expansive soil with randomly distributed fiber was investigated by reinforci...

The effects of well-defined asbestos and man-made mineral fibers, as well as glass and synthetic fluoroamphibole, on phagocytizing permanent rat tumor cells were tested. The following parameters were compared: cell proliferation as determined by cell count and 3H-thymidine incorporation, RNA synthesis by 3H-uridine uptake, protein synthesis by incorporation of 3H-labeled amino acids, protein co...

A high-strength Concrete structure is what everyone tries to achieve through the project. So many studies are being studied with various types of fibers. In this paper, I have used PVA fibers two different plasticizers. The main purpose study find amount plasticizer be and which feasible for proportions We casted 0.125%, 0.250%, 0.375%, 0.50% fiber in proportion weight cement. also their compre...
