Summary: The study revealed that ITP had some influence on the performance of concrete, partially replacing fly ash can improve the early-age compressive strength of concrete but decrease the later-age compressive strength. Increasing ITP content can enhance carbonation resistance and frost resistance, while the best sulfate attack resistance is achieved with a 50% substitution ratio.

Summary: This paper discusses the potential of recycled fine powder as an activator in fly ash based geopolymer mortar. The results show that up to 30% substitution of recycled fine powder enhances the strength and durability properties of geopolymer mortar mixes. Microstructure analysis confirms the presence of calcium content in recycled fine powder provides additional gel with geopolymer matrix and densify the microstructure to enhance all properties of geopolymer mortar.

Summary: Adding silica fume (SF) and fly ash (FA) into polypropylene (PP) filled mortar has shown to reduce porosity and water absorption while improving compressive and flexural strength. The combination of SF and FA also promoted strength development and reduced shrinkage, providing a new solution to the issues of low strength and large shrinkage in plastic mortar.

Summary: This study measured the compressive strength and shrinkage properties of fly ash-based alkali-activated materials (AAM) using different activators. The results showed that similar compressive strength can be achieved by adjusting the alkali-equivalent content and GGBFs replace percentage, regardless of the type of fly ash used. However, the shrinkage performance varied significantly depending on the type of fly ash.

Summary: The effects of Na2SO4, Na2CO3, and Na2SiO3 on the setting time, compressive strength, and hydration mechanism of binders with high volume of fly ash were investigated. Mechanical activation of fly ash was performed before chemical activation. The addition of chemical activators accelerated the hydration of Portland cement and initiated the pozzolanic reaction earlier, resulting in shorter setting time and higher early compressive strength of the binders. The combination of mechanical activation and sodium silicate activation proved to be the most effective for obtaining HVFA binders with good physicomechanical properties.

Summary: This study discusses the use of ground bottom ash together with fly ash in high performance concrete. Self-compacting concrete was applied to maximize the performance of high performance concrete. By processing bottom ash through oven-drying, sieving, and grinding, its fine consistency was achieved. The replacement of 50% cement by ground bottom ash resulted in a significantly stronger concrete with less autogenous shrinkage.

Summary: Wood biomass is widely used in the European Union, but the disposal of its ash requires proper solutions to prevent pollution. This study found that incorporating wood ash in concrete reduces compressive strength and increases capillary absorption, but has little influence on gas permeability. Wood ash with high CaO content can reduce drying shrinkage in concrete.

Summary: The Taguchi optimization approach was used to determine the optimal mix ratios for geopolymer paste production using fly ash. The method enabled the exploration of the combined effect of process parameters on output response with minimal experiments, reducing time, cost, and effort. Sixteen mixtures were prepared and tested for compressive and splitting tensile strength, with the best parameter settings resulting in a compressive strength of 24.96 MPa and splitting tensile strength of 4.40 MPa. ANOVA analysis showed significant influences of standing time and NaOH concentration on the strength values.

Summary: Incorporating rice husk ash led to an improvement in compressive strength of high-calcium fly ash geopolymer modified with borax, while using borax instead of sodium silicate resulted in decreased strength. The decrease in strength when using borax was attributed to the increase in crystalline nature of reaction products caused by lower Si/Al ratios in the gel phases formed.

Summary: By introducing synthetic microfibers and viscosity modifier agent into cement mortar mixture, layer deformation in cement printing applications can be reduced and open time can be significantly shortened. However, while fibers can improve the mechanical properties of mortar, viscosity modifier agent may have a negative effect on the mechanical properties.

The element equation is constructed within the framework of flexibility-based finite element formulation, and the material small-scale effect is consistently represented by the stress-driven nonlocal integral model. The proposed nonlocal frame element demonstrates accuracy and characteristics in different numerical examples, showing its applicability in eliminating paradoxical responses and investigating the material small-scale effect.

Summary: A strategy to enhance the energy conversion performance of a cement-based triboelectric nanogenerator (TENG) has been proposed by fabricating a cement-carbon black (CB) composite, which exhibits a 13-fold enhancement of the electrical output and the highest power density of 2.38 W/m2. The improvement is attributed to the good dispersion of conductive CB nanoparticles in the cement matrix, leading to a high dielectric constant that intensifies the triboelectric charge density of TENG.

The results showed that the addition of graphene oxide increased the compressive strength of the geopolymer and improved the bond-slip responses of fibers embedded in the geopolymer mixed with graphene oxide. Different types of fibers also exhibited different failure modes.

Summary: This research aimed to produce rice husk ash and fly ash geopolymer hollow block using NaOH activated geopolymerization. The results showed that increasing the content and fineness of rice husk ash improved the compressive strength of the geopolymer. The microstructure of the geopolymer block exhibited the presence of reaction products and a small amount of unreacted ash particles. The carbon footprint of rice husk ash and fly ash geopolymer hollow block was significantly lower compared to Portland cement. The block met the standard requirements for compressive strength and water absorption.

Summary: This study compares the release behaviors of phosphorus from biochar loaded with magnesium (Mg) and calcium (Ca). It is found that magnesium allows for a gradual and more soluble release of phosphorus, while calcium releases a smaller amount of phosphorus. Therefore, magnesium is a better additive than calcium in biochar-based fertilizers for immobilizing plant-available phosphorus and enhancing fertilizer effectiveness.

Summary: This study investigated the influence of phase change materials (PCM) on the thermal behavior of concrete sandwich panels. The integration of a PCM concrete layer in the sandwich panels maximized the heat storage capacity of PCM and slowed down the rate of heat transfer. The results showed that the thermal behavior was modified by the presence of an air gap and the application of PCM further reduced the rate of heat transfer.
