Compressive Strength Index of Crimped Polypropylene Fibres in High Strength Cementitious Matrix
Submitted: Jul 2, 2013; Accepted: Aug 18, 2013; Published: Aug 29, 2013 Abstract: Experimental Studies were conducted to analyse the influence of crimped polypropylene fibres in cementitious matrix. The compressive strength of concrete with the addition crimped polypropylene fibres for relative volume fractions of 0.1% and 0.3% were evaluated in concrete with water cement ratio as low as 0.3. H...
متن کاملProperties of antibacterial polypropylene/nanometal composite fibers.
Melt spinning of polypropylene fibers containing silver and zinc nanoparticles was investigated. The nanometals were generally uniformly dispersed in polypropylene, but aggregation of these materials was observed on fiber surface and in fiber cross-sections. The mechanical properties of the resulted composite fibers with low concentration of nanometal were comparable to those for the control P...
متن کاملAn alternative method for correcting fluorescence quenching
Under high light intensity, phytoplankton protect their photosystems from bleaching through nonphotochemical quenching processes. The consequence of this is suppression of fluorescence emission, which must be corrected when measuring in situ yield with fluorometers. We present data from the Southern Ocean, collected over five austral summers by 19 southern elephant seals tagged with fluorometer...
متن کاملEvaluation of cotton fibers stickiness by colorimetric method
Stickiness is the physical process of contaminated lint adhering to equipment. The degree of stickiness depends on chemical identity, quantity, and distribution of the sugars. The sugar in cotton fibers may be insect or plant derived. There are several methods for measuring cotton fibers stickiness. In this work, a colorimetric method was used for the measurements. In the method, honeydew was c...
متن کاملFormation and antifouling properties of amphiphilic coatings on polypropylene fibers.
We describe the formation of amphiphilic polymeric assemblies via a three-step functionalization process applied to polypropylene (PP) nonwovens and to reference hydrophobic self-assembled n-octadecyltrichlorosilane (ODTS) monolayer surfaces. In the first step, denatured proteins (lysozyme or fibrinogen) are adsorbed onto the hydrophobic PP or the ODTS surfaces, followed by cross-linking with g...
