This study presents the influence of alccofine-1203 (alccofine) on mechanical and microstructure characteristics of High Strength Concrete (HSC). A total of 7 binder proportions were developed to evaluate the Standard Consistency (SC), Initial Setting Time (IST) and Final Setting Time (FST) of the binders, and mechanical properties of HSC. Scanning electron microscopic (SEM), energy dispersive X-ray spectroscopy analysis (EDS), X-ray diffraction (XRD) were used to study the microstructure characteristics of binder pastes. 4–14% of alccofine is used to replace cement form control mix. The test results showed that compared to control mix binder, the increase in alccofine replacement levels increased the SC slightly, but decreased the IST and FST. As alccofine replacement levels increased from 4 to 10%, the compressive and tensile strengths of concrete increased but 12 and 14% replacement levels reduced the strength of the concrete. Compared to the control mix, all the alccofine based mixes exhibited higher compressive and tensile strengths. SEM and EDS analysis demonstrated that compared to all other mix binders, mix with 10% alccofine had higher amount of C-S-H gel formation, stronger dense matrix with fewer pores and microcracks as well as low Ca/Si ratio. XRD analysis showed that mix with 10% alccofine revealed higher quantification of Alites and Larnites leading to higher early as well as later strengths to the M-10%AF mix compared to other mixes.

这项研究提出了alcocofine-1203（alccofine）对高强度混凝土（HSC）的力学和微观结构特征的影响。共开发了7种粘合剂比例，以评估粘合剂的标准稠度（SC），初始凝固时间（IST）和最终凝固时间（FST）以及HSC的机械性能。用扫描电子显微镜（SEM），能量色散X射线能谱分析（EDS），X射线衍射（XRD）研究粘合剂的微观结构特征。使用4–14％的alccofine代替水泥形态控制混合物。测试结果表明，与对照混合物粘合剂相比，阿尔考芬替代水平的提高使SC略有增加，但IST和FST却降低了。随着阿尔考芬替代水平从4％上升到10％，混凝土的抗压强度和抗拉强度提高了，但是12％和14％的替代含量降低了混凝土的强度。与对照混合物相比，所有基于alcocofine的混合物均表现出更高的压缩强度和拉伸强度。SEM和EDS分析表明，与所有其他混合粘合剂相比，与10％alccofine混合的混合物具有更高的CSH凝胶形成量，更强的致密基质，更少的孔和微裂纹以及低的Ca / Si比。XRD分析表明，与10％的Alcocofine混合物混合后，Alites和Larnites的定量更高，与其他混合物相比，M-10％AF混合物的早期和后期强度更高。SEM和EDS分析表明，与所有其他混合粘合剂相比，与10％alccofine混合的混合物具有更高的CSH凝胶形成量，更强的致密基质，更少的孔和微裂纹以及低的Ca / Si比。XRD分析表明，与10％的Alcocofine混合物混合后，Alites和Larnites的定量更高，与其他混合物相比，M-10％AF混合物的早期和后期强度更高。SEM和EDS分析表明，与所有其他混合粘合剂相比，与10％alccofine混合的混合物具有更高的CSH凝胶形成量，更强的致密基质，更少的孔和微裂纹以及低的Ca / Si比。XRD分析表明，与10％的Alcocofine混合物混合后，Alites和Larnites的定量更高，与其他混合物相比，M-10％AF混合物的早期和后期强度更高。
