There is a growing concern for finding alternative solutions to construction materials in order to minimize their environmental impact as well as enhancing their service life. This study investigated the durability of cementitious mortars prepared by replacing fine aggregate (sand) with recycled tyre shreds and crumbs, aiming at providing an alternative outlet to tyre waste disposal. Tyre shreds obtained at different particle ...
Research on the combined substitution of supplementary cementitious materials (SCMs) has already demonstrated that it might be one of the few viable options to produce low-carbon concrete at scale. This paper presents an experimental investigation on the performance and durability of rice husk ash (RHA) and calcined clay (CC) in ternary blended concrete exposed to chloride attacks under wet/dry cycles.

Wide-range reference temperature-and-density based equations for the thermal conductivity of ethene and propene are given. These equations are based upon a body of critically assessed data, acquired partially using the transient hot wire method. The ethene correlation is valid from 110 to 680 K and up to 200 MPa with a maximum uncertainty of 5%. The propene correlation from 180 to 625 K at pressures up to 50 MPa, with an uncertainty of 5%....
O-xylene, m-xylene, p-xylene, and ethylbenzene are all given new representative reference equations for their thermal conductivities based upon experimental data that has been critically assessed for consistency and agreement with theory. This data was collected in part due to the transient hot wire method. The theoretically expected enhancements in the critical regions of all four agree with the data collected and can be well represented by theoretically based equations containing ...
New representative reference equations for the thermal conductivity of n-heptane are expressed based on experimental data that has been critically assessed for consistency and for agreement with theory. A large part of the data was collected by the transient hot wire method. The theoretically expected enhancement in the critical region agrees with the data collected and can be well represented by theoretically based equations containing just one adjustable parameter. The ...
