Internal and external synergistic self-curing cement concrete and preparation method thereof
The invention discloses internal and external synergistic self-curing cement concrete and a preparation method thereof, the cement concrete is internally doped with a super absorbent polymer SAP material as an internal curing material, and the surface layer of the cement concrete is sprayed with an epoxy resin coating WEC material as an external curing material; the use amount of the SAP material is 0.63 kg-2. 09 kg in terms of per cubic meter of concrete, the spraying amount of the WEC is 180 g-300 g in terms of per square meter of concrete, and the spraying time is 3.0 h-6. 0 h after pouring. Through synergistic curing of the external WEC coating and the internal SAP material, the curing efficiency of the cement concrete can be remarkably improved, and the problems that conventional curing of the cement concrete is not timely and low in efficiency are solved, so that the mechanical property and shrinkage reducing property of the cement concrete are greatly improved, and the internal and external synergistic self-curing cement concrete with excellent comprehensive performance is obtained.
本发明公开了一种内外协同自养护水泥混凝土及其制备方法，所述水泥混凝土在其内部掺加超吸水性树脂SAP材料作为内养护材料，在其表层喷涂环氧树脂涂层WEC材料作为外养护材料；以每立方米混凝土计，SAP材料用量为0.63kg～2.09kg，以每平方米混凝土计，WEC喷涂量为180g～300g，喷涂时间为浇筑后3.0h～6.0h。本发明通过外部WEC涂层和内部SAP材料的协同养护，能够显著提升水泥混凝土的养护效率，克服水泥混凝土常规养护不及时、效率低的问题，从而大幅增加水泥混凝土的力学性能和减缩性能，获得综合性能优异的内外协同自养护水泥混凝土。
