in fact, this productivity surge is the cause of the downward price pressures then here is another case that illustrates why it is important to distinguish between deflationary pressures arising from a negative aggregate demand shock versus

Due to the growing demand for steel, the amount of SS is likely to increase. The accumulation of SS not only occupies a large area of landfills, but also causes harm to the surrounding environment. Therefore, promoting the usage of SS in construction applications is recommended (Pan et al....
Fig. 4. Variations in superplasticizer demand for given Vebe consistency time. As shown in Table 4, the unit weights (whether theoretical or measured) followed a decreasing trend for mixtures prepared with increased w/b and/or containing higher RMA additions. For example, the measured unit weight...
PCE-based superplasticizer had shown to increase the early age strength of concrete in general, and it also reduces water demand of the concrete [77,79]. Therefore, it will be an interesting topic for future studies on how PCE-based superplasticizers interact and influence the performance of con...
Besides the environmental concern posed by the CO2 emissions from cement production, the continued growth in demand for concrete raises other concerns: first, the availability of the natural resources for its component materials and second, the vast size of the landfills required for disposing of the...
Although other supply and demand factors could be blocking the participation of women in business activities, discrimination in access to business resources is definitely a barrier to female entrepreneurship. Furthermore, this type of distortion might be preventing an efficient allocation of talent, with...
There are cases where high-throughput SEC analysis is in high demand. Examples are in the early stage of drug development during clone selection, or process development, where large numbers of samples need to be analyzed daily. The AdvanceBio SEC 200 Å 1.9 μm column, with its unique, ...
The fine aggregate had a modulus of elasticity of 2.67. Table 1 presents the physical properties of the natural aggregates, including their granulation distribution, as per ASTM C3363. Figure 1 illustrates the visual appearance of the natural coarse aggregates (NCA). Table 1 Particle size ...
Table 6 illustrates the outcomes of the sensitivity study. The findings show that similar to the normal SCC, w/b ratio and curing times (t) are the most significant and dominant parameters in forecasting the CS of the SCC mixes, including RP aggregates. In this research, the w/b ratio ...
