The effect of the sand-to-binder ratio on bulk packing density was examined, while the impact of water-to-binder ratio and sand-to-binder ratio on the workability and mechanical properties of UHPCC was systematically studied. Additionally, X-CT was utilized to quantitatively analyze the steel fiber distribution and mesoscopic pore structure of UHPCC. Results indicated that the sand-to-binder ratio had the significant effect on bulk density, with the optimal ratio being 1.25. The suitable fluidity of UHPCC was between 245–255mm, with an optimal water-to-binder ratio of 0.18. The compressive and flexural strength of the mortar prepared with the optimal parameters were 167.5 MPa and 41.2 MPa, respectively.","PeriodicalId":48521,"journal":{"name":"Journal of Sustainable Cement-Based Materials","volume":"12 1","pages":"1376 - 1386"},"PeriodicalIF":4.4,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45082430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the development of machine learning potentials necessitates intricate construction of descriptors, particularly for complex material systems. Therefore, the Deep Potential method, which utilizes artificial neural networks to autonomously construct descriptors, are employed to develop a deep learning-based potential for calcium silicate hydrates (the basic building block of cement-based materials) in this study. The accuracy of this potential is validated through calculations of energetics, structural, and elastic properties, demonstrating alignment with first principle calculations and an efficiency 2–3 orders of magnitude higher. Additionally, the deep potential successfully reproduces precise predictions in C-S-H models with different calcium-to-silicon ratios, thereby confirming its remarkable transferability. This potential is expected to fulfill cross-scale computations and bottom-up design of cement-based materials with both high accuracy and efficiency.","PeriodicalId":48521,"journal":{"name":"Journal of Sustainable Cement-Based Materials","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135703531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The particle groups of MGYRS had good fractal characteristics, and the fractal dimension had a better correlation with the particle size, distribution and specific surface area of MGYRS, which could well reflect the changes in the physical properties of MGYRS. After mechanical milling, the analysis by XRD, FT-IR and XPS microscopic tests revealed that: the crystallinity and grain size of mineral crystals in MGYRS decreased with the increase in milling time. The electron binding energy of Si2p, Al2p and O1s shifted to the low-energy direction, and the chemical valence state of silicon atoms appeared Si3+ due to the breakage of the Si-O-Si/Al chemical bond. These changes in internal structure and chemical valence state were the microscopic manifestations of mechanochemical effects. The activation rate of MGYRS increased with the increase of grinding time, which was the macroscopic manifestation of mechanochemical effects.","PeriodicalId":48521,"journal":{"name":"Journal of Sustainable Cement-Based Materials","volume":"12 1","pages":"1322 - 1333"},"PeriodicalIF":4.4,"publicationDate":"2023-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41685264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A self-compacting concrete was considered in this study as to maximize the properties of high performance concrete. Bottom ash was processed to a fine consistency by oven-drying, sieving, and grinding. Ordinary Portland cement (OPC), sieved and ground bottom ash (GBA), and fly ash (FA) were used for producing high performance concrete at a W/B ratio of 0.27. Replacement of 50% cement by GBA produced 101.0 MPa concrete at 28 days: 21.6% stronger than OPC concrete. The 50% GBA mixture needed a greater quantity of superplasticizer to satisfy slump flow requirements for self-compacting concrete, but that dosage was reduced with a partial replacement of GBA by FA. Elastic moduli of all blended concretes matched OPC concrete. However, the blended concretes experienced much less autogenous shrinkage. Pastes containing GBA and FA have less portlandite than OPC paste. In addition, replacing OPC by GBA–FA substantially reduced cumulative heat evolution.","PeriodicalId":48521,"journal":{"name":"Journal of Sustainable Cement-Based Materials","volume":"12 1","pages":"1270 - 1285"},"PeriodicalIF":4.4,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41834744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four kinds of environments (air, wet-dry cycles, 20 °C water, and 40 °C water) are chosen to simulate real service environments. The tensile property, ultrasonic pulse velocity, crack characteristic, and water absorption of FA-EGC are measured to evaluate the self-healing properties. The test results show that the existence of water and the increasing of temperature can benefit the self-healing performance of FA-EGC. In addition, the 28-day self-healing products are determined by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), and scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) to explore the mechanism of the self-healing in different environments. The results demonstrate that N–A–S–H gels could be the main self-healing products in the air condition. While in the other environments with water, the (N/C)–A–S–H gels would be the primary products.","PeriodicalId":48521,"journal":{"name":"Journal of Sustainable Cement-Based Materials","volume":"12 1","pages":"1228 - 1241"},"PeriodicalIF":4.4,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43976467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The early-age autogenous shrinkage and TC of concrete with various proportions of polypropylene (PP) macro fiber (0%, 0.3%, 0.6%, and 0.9%) were investigated utilizing the Temperature Stress Test Machine. Fiber dispersion and the microstructure of concrete mixtures were also analyzed.

Although there have been some related reviews, the comprehensiveness and advancedness need to be further improved. This paper is a detailed review of previously conducted studies to explore the influence of NS in cementitious composites for evaluating mechanical properties and durability. The impact of NS on the fresh state, i.e. setting time and workability, and in the hardened state, i.e. compressive, flexural, and split tensile strengths is considered. Besides, the long-term durability is discussed that include permeability, resistance against acid and base attack, abrasion resistance, and carbonation resistance. Furthermore, volume stability and microstructure of concrete with NS are presented. A huge number of studies showed the positive effect of NS with optimized content for improving the concrete properties, while a negative effect was observed with the use of excess NS content. The inclusion of NS in cementitious composites substantially enhances the mechanical properties, durability and microstructure. Meanwhile, better dispersibility is the key to ensure the strengthening effect of NS, which can be improved by changing the morphology/size of NS, optimizing the stirring method, and adding surfactants. Further investigation of the application of NS in special concrete is its development direction, and the effect of NS on the microstructure of main hydration products needs to be further explored.","PeriodicalId":48521,"journal":{"name":"Journal of Sustainable Cement-Based Materials","volume":"12 1","pages":"1286 - 1306"},"PeriodicalIF":4.4,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44754070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
