CBR Characteristics of Cementitious Graded Gravel Soils by Curing Methods

Improvement of Forest Road Gravel Surfacing Quality by Nano-polymer CBR PLUS

In this study, CBR PLUS was used on gravel roads to reduce erosion and consequently maintenance costs of forest road network. Nano-polymer CBR PLUS with weight percentages of 0.25, 0.50, 0.75 and 1.00% in water were added to the surfacing materials of a forest road in Nekachoob Company of Iran. A comparative soil chemical and mechanical test for untreated and treated soil was carried out to obs...

Strength Characteristics of Self-curing Concrete

Today concrete is most widely used construction material due to its good compressive strength and durability. Depending upon the nature of work the cement, fine aggregate, coarse aggregate and water are mixed in specific proportions to produce plain concrete. Plain concrete needs congenial atmosphere by providing moisture for a minimum period of 28 days for good hydration and to attain desired ...

Characterization of Hydrogel Curing Methods for Manufacturability

In the field of soft robotics, hydrogels possess material properties that allow them to function as both soft strain sensors and electrodes for dielectric elastomer actuators. However, there is still much that needs to be understood about the curing process of hydrogels and the resulting material characteristics before devices can be reliably manufactured. In this study, we investigated the eff...

Filtration of broadly graded soils: the reduced PSD method

Flexural Behavior of Cementitious Composites Reinforced by Synthetic Fibers

The application of fibers to reinforce cementitious materials is a well-known subject. At first, asbestos fibers are used in industrial process to produce fiber reinforced cement sheets. Thereafter, various types of synthetic fibers are produced and used as asbestos substitutes. The aim of the present work is to evaluate the effect of synthetic fibers on the flexural behavior of cementitious co...
