Abstract ：
In this study, lightweight ultra-high performance concrete (LUHPC) was prepared by replacing different components in the mixture of ultra-high performance concrete (UHPC) with hollow glass microspheres (HGMs). The specimens with different curing ages were evaluated in order to investigate the influencing effects of HGMs on the performance of UHPC. Additionally, isothermal calorimetry and thermogravimetric experiments were conducted to quantify the pozzolanic activity of HGMs and substituted supplementary cementitious materials. Scanning electron microscopy was used to observe and analyze the morphology of LUHPC. The results showed that HGMs possessed moderate reactivity which was responsible in increasing the degree of hydration and reducing the impact on the mechanical properties, where inert materials in the UHPC mixture was replaced. High-temperature curing promotes the reaction of the HGMs and significantly enhanced the strength of LUHPC, resulting in mechanical performance notably higher than that obtained under standard curing. By optimizing mixture proportion, a LUHPC mixture with a density of 1890 kg/m3 achieved 134 MPa in compressive and 19 MPa in flexural strength.

Abstract ：
Pre-mixed fluidized solidified soil (PFSS) has the advantages of pumpability, convenient construction, and a short setting time. This paper took the excavated loess in Fuzhou as the research object and used cement-fly-ash-ground granulated blast furnace slag-carbide slag as a composite geopolymer system (CFGC) to synthesize PFSS. This study investigated the fluidity and mechanical strength of PFSS under different water-solid ratios and curing agent dosages; finally, the microstructure of the composite geopolymer system-pre-mixed fluidized solidified soil (CFGC-PFSS) was characterized. The results showed that when the water-solid ratio of PFSS increased from 0.46 to 0.54, the fluidity increased by 77 mm, and the flexural strength and compressive strength at 28 d decreased to 450.8 kPa and 1236.5 kPa. When the curing agent dosage increased from 15% to 25%, the fluidity increased by 18.0 mm, and the flexural strength and compressive strength at 28 d increased by 1.7 times and 1.6 times. A large number of needle-like AFt, C-S-H gel, and C-(A)-S-H gel coagulate with soil particles to form a three-dimensional reticular structure, which is the mechanism of the strength formation of PFSS under the action of CFGC.

Abstract ：
This study introduces an innovative phase-change composite aggregate, integrating paraffin (PA) into waste aerated autoclaved concrete (AAC), enhancing energy efficiency in building temperature regulation. The composite, with a 62 % paraffin volume fraction, showed significant improvements in dry density (71.4 %), compressive strength (34.0 %), and failure strain (25.0 %) over unmodified AAC. It demonstrated a low paraffin leakage rate under 5 %, thermal conductivity of 0.551 W/(m & sdot;K), a phase transition temperature range of 5-45 degrees C, a latent heat of 42.82 J/g, and maintained thermal stability after 300 cycles. Finite element analysis highlighted the impact of porosity and pore size on the compressive strength, while heat transfer simulations underscored the AAC's pore structure's role in convective heat transfer during paraffin melting. Concrete with PA-filled AAC achieved a 28-day compressive strength of 38.2 MPa and a maximum temperature reduction of 15 degrees C during heating, outperforming conventional concrete. This research provides valuable insights into the mechanical and thermal performance of phase-change composites for advanced building materials.

Abstract ：
Fluidized solidified soil (FSS) is an innovative backfill material that offers benefits such as easy pumping and straightforward construction. This study examined how varying the water-soil ratio and the curing agent dosage affect the properties and microstructure of FSS. The strength development mechanism was investigated when composite solidification agents were used. The findings show that both the water-solid ratio and the curing agent dosage can affect the microstructure of FSS, thereby affecting its performance. When the water-solid ratio increases from 0.52 to 0.56, the unconfined compressive strength (UCS) and flexural strength of the FSS decrease by 34.1% and 39.3% after 28 d. Conversely, the curing agent dosage increasing from 10% to 30% will increase both UCS and flexural strength by 11.2 times and 11.1 times. As the curing age increases, the number of cracks at failure point in the FSS will increase and lead to a more complete failure. Numerous needle-like AFt, C-S-H gel, and C-(A)-S-H gel create a three-dimensional network by adhering to soil particles.

Abstract ：
Although sugarcane bagasse ash (SCBA) possesses favorable cementitious properties, previous research has primarily focused on improving the mechanical performance of conventional concrete- or cement-based composites. Limited attention has been given to ultra-high-performance concrete (UHPC) with SCBA, especially regarding its tensile -sensing properties. This study aimed to comprehensively evaluate the effect of SCBA on the mechanical, electrical, and tensile self-sensing properties of UHPC. The results demonstrated that incorporating SCBA below the critical concentration of 3.0 wt% enhanced the mechanical properties of UHPC. Notably, adding 3.0 wt% SCBA remarkably improved the compressive, flexural, and tensile strengths of UHPC, resulting in increases of 13.1%, 17.4%, and 20.6%, respectively. However, excessive incorporation of SCBA adversely affected the mechanical properties due to reduced workability of UHPC, increased generation of harmful voids, and a lower degree of hydration caused by the excess SCBA. Furthermore, the inclusion of SCBA influenced the electrical resistivity of UHPC, and specifically, an SCBA content of 0.3 wt% yielded the maximum electrical resistivity. Moreover, incorporating SCBA in UHPC enhanced its tensile stress-sensing performance compared to SCBA-free UHPC. Among the various SCBA contents tested, UHPC with 0.3 wt% SCBA presented the best linearity, with values of 8.8% for loading and 17.0% for unloading, respectively, which were significantly lower than those for SCBA-free UHPC, which were 14.0% and 60.0%, respectively. Additionally, UHPC with 0.9 wt% SCBA gained the lowest hysteresis and repeatability, with values of 13.3% and 5.3%, respectively, which were much lower than those for SCBA-free UHPC, which were 50% and 51.6%, respectively. The tensile stress-sensing performance of UHPC is influenced by three key aspects: the gap between adjacent conductive fillers, contact resistance, and the connectivity of the electrical network, which are subject to change due to varying stress states and SCBA concentrations. This study should aid SCBA use and promote UHPC's practical applications.

Abstract ：
This study tackled the issue of inferior fiber-matrix adhesion in bamboo fiber (BF) reinforced cement-based composites, a critical factor impacting their performance and service life. Our approach introduces a novel application of silane coupling agents (SCAs) to improve the compatibility of BF with cement matrices. We utilized isocyanate propyl triethoxy silane (IPTS) in a pioneering manner, and used gamma-glycidyl ether oxypropyl trimethoxysilane (KH560), respectively, to chemically modify the BFs. This modification strategy was designed to enhance the adhesion between BFs and the cement matrix through the SCAs' interaction with hydroxyl groups on the BF surface and their involvement in the cement hydration process. Our findings reveal that the modified BFs, when incorporated into cement composites, not only match the compressive strength of the control but also show a remarkable increase of over 20 % in flexural strength and over 30 % in tensile strength. Additionally, the modified BFs reduce drying shrinkage by more than 19 % after 90-day curing, and similarly significant reductions are observed in chloride ion penetration and freeze-thaw cycle failure rates. Notably, IPTS outperforms KH560 in enhancing mechanical strengths and durability, likely due to the formation of more siloxane bonds on the fiber surface, leading to stronger cement matrix interaction. This research presents a cost-effective method to improve the performance of BF/cement composites, paving the way for broader utilization of BFs in sustainable construction materials.

Abstract ：
Pervious concrete has a unique open-skeleton structure and high permeability, which effectively control water runoff, mitigate urban heat island effects, and reduce traffic noise in urban constructions. However, low strength, easy granulation, and poor durability often limit its application in pavement engineering. As a polymer binder, vinyl ester (VE) resin has high strength, wear resistance, durability, and corrosion resistance, which can remedy the shortage of pervious concrete. In this work, by optimizing the aggregate gradation and curing temperature, high-performance pervious concrete using VE resin as binder was fabricated. To further improve the performance of VE binder, renewable acrylated epoxidized soybean oil (AESO) and diphenylmethane diisocyanate (MDI) were used to increase the crosslinking degree of the resin and the durability of pervious concrete. When using 15% AESO and 10% MDI based on the weight of VE, the pervious concrete achieved an enhanced flexural strength of up to 7.72 MPa. A significant improvement was achieved by incorporating 50 wt% solid wastes copper slag into the pervious concrete, the compressive strength and flexural strength reached 37.72 MPa and 7.53 MPa, respectively. The permeability coefficient of the permeable concrete was 2.64 mm/s, and the connected porosity was 11.33%, which are higher than the requirements of China national standard. The satisfactory durability of pervious concrete was also verified through freeze-thaw, abrasion, and aging tests. This work offers a viable strategy for cost-efficient and sustainable high-performance pervious concrete, providing insights into the utilization of renewable feedstocks and solid wastes in civil materials.

Abstract ：
The production of manufactured sand and stone processing can cause dust pollution due to the generation of a significant amount of stone powder. This dust (mainly granite powder) was collected and incorporated as a cement replacement into mass-manufactured sand concrete in order to enhance the mechanical properties and microstructures. The heat of the hydration was measured by adding the granite powder into the cementitious material system. The mechanical properties, autogenous shrinkage, and pore structures of the concrete were tested. The results showed that the mechanical strength of the concrete increased first and then decreased with the increase in granite powder content. By replacing the 5% cement with the granite powder, the 28 d compressive and flexural strength increased by 17.6% and 20.9%, respectively. The autogenous shrinkage was mitigated by the incorporation of the 10% granite powder and decreased by 19.7%. The mechanism of the granite powder in the concrete was studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), and mercury intrusion porosimetry (MIP). The porosity decreased significantly within the 10% granite powder. A microstructure analysis did not reveal a change in the type of hydration products but rather that the granite powder played a role in the microcrystalline nucleation during the hydration process.
