The invention discloses a high-temperature-resistant anti-cracking concrete and a preparation method thereof. The preparation method comprises the following steps: dissolving a naphthalene water reducer in water, adding graphene, dispersing graphene to prepare a graphene solution, adding an EVA emulsion into the graphene solution, uniformly stirring, carrying out ultrasonic treatment to obtain a mixed solution, adding the mixed solution into concrete production equipment, adding nano titanium dioxide, nano silicon dioxide, nano carbon fibers, cement, fly ash, river sand and gravels into the mixed solution, uniformly mixing to obtain semi-finished product concrete, and finally performing ultrasonic treatment on the semi-finished product concrete to obtain the high-temperature-resistant anti-cracking concrete. The nano titanium dioxide, nano silicon dioxide and nano carbon fibers are added into the high-temperature-resistant anti-cracking concrete, the high-temperature-resistant performance and the compressive strength of the concrete are improved, by adding the graphene, the brittleness of cement is improved, the toughness of the concrete is improved, and therefore microcracks are reduced, and the durability of the concrete is improved.
本发明公开了一种耐高温抗裂混凝土及其制备方法，通过将萘系减水剂溶解于水中，然后加入石墨烯，将石墨烯分散制得石墨烯溶液，向石墨烯溶液中加入EVA乳液，搅拌均匀后用超声波处理，得到混合溶液，将混合溶液加入到混凝土生产设备中，然后向混合溶液中投入纳米二氧化钛、纳米二氧化硅、纳米碳纤维、水泥、粉煤灰、河砂、碎石混合均匀后，得到半成品混凝土，最后对半成品混凝土进行超声波处理，得到该耐高温抗裂混凝土；该耐高温抗裂混凝土中加入纳米二氧化钛、纳米二氧化硅、纳米碳纤维，提高了混凝土的耐高温性能和抗压强度，通过加入石墨烯，改善了水泥脆性增加了混凝土的韧性从而减少微裂缝的产生，从而提高混凝土的耐久性。
