▪ Abstract The cement industry contributes about 5% to global anthropogenic CO2 emissions, making the cement industry an important sector for CO2-emission mitigation strategies. CO2 is emitted from the calcination process of limestone, from combustion of fuels in the kiln, as well as from power generation. In this paper, we review the total CO2 emissions from cement making, including process and energy-related emissions. Currently, most available data only includes the process emissions. We also discuss CO2 emission mitigation options for the cement industry. Estimated total carbon emissions from cement production in 1994 were 307 million metric tons of carbon (MtC), 160 MtC from process carbon emissions, and 147 MtC from energy use. Overall, the top 10 cement-producing countries in 1994 accounted for 63% of global carbon emissions from cement production. The average intensity of carbon dioxide emissions from total global cement production is 222 kg of C/t of cement. Emission mitigation options include en...

Carbon dioxide emissions from the global cement industry

Simply supported bridges consisting of five I-section concrete girders are analyzed using the finite-element method. The main parameters of this study are: girder spacing (1.8–2.7 m), span length (25–35 m), skew angle (0–60°), and different arrangements of internal transverse diaphragms. Results of reliable analysis based on the finite-element method show that, in right bridges, American Association of State Highway and Transportation Officials distribution factors are conservative and in skew bridges, these factors are very conservative.

Load Distribution Factors in Simply Supported Skew Bridges

Ten large-scale tests on floors comprising hollow-core slabs supported on beams were carried out. All tests ended in web shear failure of slabs close to the supports of the beam. In one test the shear resistance was not reduced, but in others was only 40–77% of the reference value measured on non-flexible supports. In one test yielding of the reinforcement in the supporting beam preceded failure. In other tests the beams did not yield and their deflection at slab failure was very small, typically \db\N/1,000–\iL\i\db/300. Reduction of shear resistance is due to transverse deformation of the slab ends resulting from deflection of the beam. The reduction is so great that it must be considered in design, even though collapses due to such reduction, thanks to the high safety factors applied, have neither occurred nor are likely to occur in conventionally designed floors.

Shear Resistance of PHC Slabs Supported on Beams. I: Tests

The shear strength of extruded prestressed precast hollow-core slabs, investigated experimentally and analytically, is reported Ten slab specimens have been tested, all failing in the shear mode (six in shear tension mode) The analysis explores ways of employing existing procedures for predicting the shear capacity It is concluded that modification of the FIP recommendations would lead to a better approximation of the test results
