The invention provides a novel concrete and a preparation method thereof, and relates to the field of concretes. The problem that existing concrete has many holes is solved. The novel concrete raw material comprises, by weight, 50-85 parts of Portland cement, 10-25 parts of fly ash, 45-77 parts of aggregate, 30-66 parts of bentonite, 18-35 parts of graphene oxide, 16-29 parts of nano-silica sol, 9-19 parts of a filler, 2-7 parts of a dispersing agent, 1-6 parts of a pumping agent, 8-16 parts of a defoaming agent, 7-16 parts of an anti-cracking agent and 78-96 parts of water. The novel concretehas few internal holes, the corrosion resistance of the concrete is effectively improved, and the preparation method is simple. 本发明提供了一种新型混凝土及其制备方法，其涉及混凝土领域，旨在解决现有混凝土孔洞多的问题，新型混凝土原料按重量份包括以下组分：硅酸盐水泥50-85份，粉煤灰10-25份，骨料45-77份，膨润土30-66份，氧化石墨烯18-35份，纳米硅溶胶16-29份，填料9-19份，分散剂2-7份，泵送剂1-6份，消泡剂8-16份，抗裂剂7-16份，水78-96份。本发明的新型混凝土内部孔洞少，有效提高了混凝土的抗腐蚀性能，而且制备方法简单。
