agricultural waste fibers have been found to be suitable as reinforcement in cement-based composites, but studies on oil palm fiber as reinforcement in gypsum-cement wall panels are scarce. a mixture of two equal weights of gypsum and cement, with water-binder ratios of 0.45 and 0.55 were prepared. in each mix a varying percentage of fiber contents of 2%, 3% and 4% by weight of the binders were...

Activated carbon fiber composites show gnat promise as fixed-bed catalytic reactors for use in environmental applications such as flue gas clean-up and ground water decontamination. A novel manufacturing process produces low density composites h m chopped carbon fibers and binders. These composites have high permeability, can be activated to have high surface area, and have many potential envir...

The ultra-high-performance fiber-reinforced cementitious composite (UHPFRC) is a new generation of building material with extremely high mechanical strength and durability, which can be used for ultra-high, thin-wall or long-span construction, that prolongs the service life construction in severe environments. In this study, UHPFRC was prepared range local ecological admixture to decrease mater...

Carbon fiber composite materials are increasingly being used in the design and fabrication of transportation vehicles. In particular, the aviation industry is increasing transitioning from metals to this class of composites due to the high strength and low weight of the materials. Most aviation structural composites are thermoset, meaning they require thermal processing to harden the epoxy. In ...

Conventional concrete production that uses ordinary Portland cement (OPC) as a binder seems unsustainable due to its high energy consumption, natural resource exhaustion and huge carbon dioxide (CO₂) emissions. To transform the conventional process of concrete production to a more sustainable process, the replacement of high energy-consumptive PC with new binders such as fly ash and alkali-acti...

This work addresses the development and assessment of a fiber optical viscometer using a simple and low-cost long-period fiber grating (LPFG) level sensor and a capillary tube mechanism. Previous studies of optical viscosity sensors were conducted by using different optical sensing methods. The proposed optical viscometer consists of an LPFG sensor, a temperature-controlled chamber, and a cone-...

The reinforcement of stabilized soils with fibers arises as an interesting technique to overcome the two main limitations soils: weak tensile/flexural strength and higher brittleness behavior. These types mixtures require extensive laboratory characterization since they entail study a great number parameters, which consumes time resources. Thus, this work presents alternative approach predict u...
