Steel fiber graphite concrete as well as preparation method and application thereof
The invention is applicable to the technical field of concrete, and provides steel fiber graphite concrete as well as a preparation method and application thereof. The steel fiber graphite concrete comprises a concrete base material, and the concrete base material is doped with graphite and steel fibers; the mixing amount of the graphite is 2% to 5% of the mass of the fine aggregate in the concrete base material, and the mixing amount of the steel fibers is 0.2% to 0.8% of the mass of the concrete base material. According to the steel fiber graphite concrete provided by the embodiment of the invention, the graphite and the steel fibers are doped into the concrete base material, so that the heat conductivity coefficient, the breaking strength and the compressive strength of the steel fiber graphite concrete can be remarkably improved, and the running stability and the heat exchange efficiency of an energy pile can be guaranteed when the steel fiber graphite concrete is applied to the energy pile.
本发明适用于混凝土技术领域，提供了一种钢纤维石墨混凝土及其制备方法和应用，该钢纤维石墨混凝土包括混凝土基料，所述混凝土基料中掺有石墨和钢纤维；其中，石墨的掺量为混凝土基料中细骨料质量的2%~5%，钢纤维的掺量为混凝土基料质量的0.2%~0.8%。本发明实施例提供的钢纤维石墨混凝土，通过在混凝土基料中掺入石墨和钢纤维，可以显著提高钢纤维石墨混凝土的导热系数、抗折强度和抗压强度，故将该钢纤维石墨混凝土应用于能量桩中，能保证能量桩运行的稳定性和换热效率。
