The dosage of mineral powder has a complex influence on the compressive strength of self-compacting concrete, among which the pore structure is a key determining factor. This study investigated the effects of different dosages of mineral powder (0%, 5%, 10%, 20%, and 30%) on the workability, mechanical properties, and pore distribution in C80 self-compacting concrete. The research results show that an appropriate dosage of mineral powder (0–20%) can significantly improve the spreadability and fluidity of C80 self-compacting concrete. This phenomenon is mainly attributed to the shape effect and micro-aggregate effect of mineral powder, which improve the fluidity of concrete, reduce the viscosity of the paste, and thereby increase the spreadability and gap-passing rate. By testing the BSD-PS1/2 series fully automatic specific surface area and pore size analyzer, we found that there are columnar pores and ink bottle-shaped pores in C80 self-compacting concrete, as well as a small amount of plate-like slit structures. Our observations with an SEM scanning electron microscope revealed that the width of micro-cracks and micro-holes is between 1 and 5 μm and the diameter is between 3 and 10 μm. These microstructures may have an impact on the mechanical properties of the structure. By applying fractal theory and low-temperature liquid nitrogen adsorption tests, this study revealed the relationship between the fractal characteristics of internal pores in C80 self-compacting concrete and the dosage of mineral powder. The results show that with the increase in mineral powder dosage, the fractal dimension first decreases and then increases, reflecting the change rule of the complexity of pore structure first decreasing and then increasing. When the dosage of mineral powder is about 20%, the compressive strength of SCC reaches the maximum value, and this dosage range should be considered in engineering design. Full article

The aim of this paper is to conduct reliability analysis of flexural strength design provisions of FRP-reinforced concrete (FRP-RC) beams in accordance with CSA S806. In particular, different load combinations, including dead, live, wind and snow, are investigated. Through this, the various sources of uncertainty related to the material strength and geometrical properties are taken into account when examining the reliability of the flexural strength provisions of CSA. The uncertainty inherent in the flexural strength model is assessed using a large experimental database of 303 FRP-RC beams assembled from the literature. The first-order reliability method (FORM) is employed for reliability analysis. The results indicated that the reliability index, β, of the current code is not consistent for different failure modes, yielding overly conservative values for the FRP rupture mode (β = 4.895) compared to the concrete crushing mode of failure (β = 3.726). Based on the reliability-based calibration of the existing design equations, modifications to the current provisions are proposed to achieve a variety of target reliability indexes of 3.5, 3.8, and 4 for the failure modes of concrete crushing and FRP rupture, separately, and for a common range of load ratios in the different load combinations. The results presented enable designers to choose proper strength-reduction factors to reach the desired level of safety for each failure mode in the flexural design of FRP-RC beams. Full article

Engineers commonly use the 28-day characteristic strength of concrete for project calculations, but this may not reflect the full-strength potential, especially in concretes with supplementary cementitious materials (SCMs). SCMs, known for their slow reactivity, often delay optimal strength beyond 28 days, requiring higher cement content to speed up early strength development, thus increasing production costs. This study examined the relationship between concrete age and mechanical strength across eight cement types, including tests for axial compression, water absorption, void index, and specific mass. The findings showed that pozzolan and slag cements gained significant long-term strength due to slow pozzolanic reactions. Conversely, limestone filler mixes had lower initial strength and slower progress, likely due to increased porosity from fine fillers. A correlation was found between higher pozzolan content and improved durability, including reduced water absorption and void index. Cost analysis indicated that optimizing cement mix designs for targeted strength levels could reduce production costs, especially for concretes with high SCM content. Using long-term characteristic strength rather than the traditional 28-day strength resulted in approximately 14% savings, particularly for slag- and pozzolan-based cements. The savings were less significant for other cement types, emphasizing the importance of adjusting mix designs based on both performance and financial considerations. Full article
