High-strength and high-impermeability few-layer graphene concrete and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to high-strength and high-impermeability few-layer graphene concrete and a preparation method thereof. Thehigh-strength and high-impermeability few-layer graphene concrete comprises the following components in parts by mass: 360-390 parts of cement; 1000-1250 parts of stone; 630-660 parts of medium sand;0.01-0.35 part of few-layer graphene; and 200-240 parts of water. According to the invention, the few-layer graphene plays a bridging role in the high-strength and high-impermeability few-layer graphene concrete, so that the filling of internal pores of the high-strength and high-impermeability few-layer graphene concrete, the connection of micro-cracks and the improvement of the impermeability ofthe concrete are facilitated; herein, the few-layer graphene has a template effect due to the large specific surface area, so that formation of hydration products is promoted, the interior of the concrete is more compact, and therefore the internal microstructure of the concrete is improved, and the mechanical property is improved; compared with graphene oxide, the few-layer graphene does not need to be modified and oxidized, and the cost is low.
本发明属于建筑材料技术领域，特别涉及一种高强高抗渗少层石墨烯混凝土及其制备方法。本发明提供了一种高强高抗渗少层石墨烯混凝土，包括以下质量份的组分：水泥360～390份；石子1000～1250份；中砂630～660份；少层石墨烯0.01～0.35份；水200～240份。在本发明中，少层石墨烯在高强高抗渗少层石墨烯混凝土中起到桥接作用，有利于填充高强高抗渗少层石墨烯混凝土内部孔隙、连接微裂缝，提高混凝土抗渗性能；少层石墨烯因其较大的比表面积而具有模板效应，促进水化产物的形成，使混凝土内部更加致密，从而改善混凝土内部微观结构，提高力学性能；相比于氧化石墨烯，少层石墨烯无需改性氧化，成本低廉。
