Summary: This investigation focuses on predicting and optimizing the total powder content of self-consolidating concrete. The study shows that the relationship between the responses and the constituent materials can be used to predict the characteristics of SCC, reducing repetitive laboratory testing and enabling quick decision-making for building applications. The results also indicate that the slump flow increases with the increase in certain parameters, and the partial replacement of cement by FA decreases the compressive strength at early ages.

Summary: The study compared the flow assessment of partial replacement of cement using Basalt powder (BP) in developing Self-Consolidating Concrete (SCC) with Limestone powder (LP), showing that mixtures with more than 15% BP replacement had higher yield stress values, and BP mixtures generally had higher viscosity values except for those with 15%-20% replacement where LP had slightly higher values. Due to the morphological and chemical nature of volcanic powder BP, mixtures with BP replacement showed superior and durable compressive strength development at 56 days.

Summary: In recent years, researchers have focused on using various industrial by-products and waste materials in concrete to reduce environmental impact and conserve natural resources. This study investigates the properties, bond stress-slip behavior, and use of self-compacting rubberized concrete (SCRC) with and without silica fume. The results show that the replacement of sand with crumb rubber (CR) has a negative effect on the fresh and hardened properties of SCRC, but the addition of silica fume improves its mechanical properties and bond strength. By replacing 10% of the sand with CR and adding silica fume, the SCRC achieves similar properties and bond strength to normal self-compacting concrete, showing its potential for structural applications.

Summary: Experimental and numerical investigations were conducted to study the performance of UHPFRC continuous deep beams with openings. The test program included seven beams with openings and one solid beam. The position, height, width of the opening, and ratio of transverse reinforcement were the variables. The results showed that the failure mode depended on the position and size of the opening, with shear failure occurring in the diagonal strut between the support and the opening edges. The proposed 3-D numerical model successfully predicted the failure load and performance of the beams.

Summary: This paper investigates the torsional behavior of UHPFRC shallow and deep beams with a compressive strength of 190.2 MPa through experimental and numerical studies. The experiment results show that increasing the stirrups' spacing has a minimal effect on the ultimate torsional strength of the beams. It is found that the torsional web reinforcement ratio can be safely taken to be 40% of the minimum required value, and the maximum stirrups spacing can be determined by the lesser of twice the beam width or 300 mm. The cracking strength equation used in current codes is modified to account for the L/h ratio and steel fibers content.

Summary: This study analyzes the erosion mechanisms of NaCl solution on asphalt concrete and finds that NaCl solution softens asphalt and promotes the intrusion of crystalline salt into it. Salt crystallization alters the surface roughness of aggregates, resulting in a decrease in skid resistance but an improvement in compressive strength. Additionally, the concentration of NaCl solution initially has no significant impact on the mechanical performance of asphalt concrete, but its domination gradually increases with the intensification of cyclic effects.

Summary: This paper investigates the effect of freezing and thawing cycles on the tensile behavior of cracked ultra-high performance concrete (UHPC). The results show that long-term freezing and thawing action deteriorates the cracking strength, tensile strength, tensile strain, and strain energy of cracked UHPC. On the other hand, the action of water generally favors the development of tensile properties of UHPC. The crack distribution tends to be unsaturated under freezing and thawing environment, and the re-hydration reaction is hindered. The pore structure near the crack varies under different environments.
