Abstract

The control of concrete properties depends on the cement hydration process and the formation of hydrated phases. The increase of hydrated phases and the increase of hydration kinetics increase the mechanical properties of cement. Additives can affect the final properties of concrete. In this research, the properties of MgO-PEG nanocomposite on the mechanical properties of cement paste were investigated. The formation of MgO-PEG nanocomposite was investigated by XRD, DTA characterization techniques. Then different percentages of MgO-PEG nanocomposite were added to the cement paste and its strength and heat of hydration were investigated. The compressive strength increased by 89.76%, 106.02%, 98.87%, and 99.45% for the samples containing 0, 1, 3, and 5 wt% MgO-PEG nanocomposites, respectively. The results demonstrated that PEG alone may decrease compressive strength and hydration-related performance due to increased water absorption, whereas forming a MgO–PEG composite effectively counteracts this issue by improving hydration and microstructural densification.

MgO-PEG纳米复合材料掺入对水泥浆体性能的影响

混凝土性能的控制取决于水泥水化过程和水化相的形成。水化相的增加和水化动力学的提高提高了水泥的力学性能。添加剂会影响混凝土的最终性能。本研究考察了MgO-PEG纳米复合材料的性能对水泥浆体力学性能的影响。采用XRD、DTA等表征技术对MgO-PEG纳米复合材料的形成进行了研究。然后将不同比例的MgO-PEG纳米复合材料加入到水泥浆体中，考察其强度和水化热。含有0、1、3和5 wt% MgO-PEG纳米复合材料的样品的抗压强度分别提高了89.76%、106.02%、98.87%和99.45%。结果表明，单独使用PEG可能会由于吸水率增加而降低抗压强度和水化相关性能，而形成MgO-PEG复合材料通过改善水化和微结构致密性有效地抵消了这一问题。
