STUDIES ON BLENDED CEMENTS, II

Environmental CRIteria for CEMent based products ECRICEM Phase I: Ordinary Portland Cements Phase II: Blended Cements EXECUTIVE SUMMARY

Clinical studies of dental cements. II. Further investigation of two zinc oxide--eugenol cements for temporary restorations.

a compressive strength of 2,200 psi and the other with a compressive strength of 3,500 psi, were the most satisfactory for cementing temporary restorations. The data collected, however, were not sufficient in quantity to differentiate between the two cements. There was the possibility that one or the other of the two cements might prove superior, and this investigation was undertaken to collect...

Studies on Effect of Injection Timing of Graphene Nanoparticles Blended Simarouba Biodiesel Blend on CI Engine

Graphene is a monolayer carbon atoms discovered in the recent past which has inspired researchers in a wide range of applications. It has a surface area as high as 2630 m2/g and thermal conductivity value of 3000 W/mK-1 at room temperature. It is chemically the most reactive form of carbon with one carbon atom exposed to reaction from each side. Stable dispersion of graphene was achieved using ...

Meta-Analysis of Studies on the Effect of Blended Learning on Academic Performance in Iran

The purpose of this research was to conduct a meta-analysis of the studies on the effect of blended learning on academic performance in Iran. The meta-analysis was based on the estimated effect size of blended learning on academic performance. 211 studies were identified in the period 2010-2017, of which 20 research documents were selected using non-probability (purposive) sampling. Initial dat...

effect of grinding method on energy consumption and particle size distribution of blended cements

the benefits of using mineral admixtures as a partial replacement of portland cement (pc) are well established in the literature. economic and environmental advantages by reducing co2 emissions are well known. this paper examines the influence of intergrinding and separate grinding on the amount of energy consumption, blaine fineness and particle size distribution (psd) of blended cements, name...
