Ultra-high performance concrete with low shrinkage and high elastic modulus and preparation method thereof
The invention provides ultra-high performance concrete with low shrinkage and high elastic modulus and a preparation method thereof, and belongs to the technical field of concrete preparation. Comprising cement, aggregate, water, chemical additives, mineral admixtures, plant fibers and camphor. The plant fibers are added into the concrete, so that the tensile strength and the crack resistance of the concrete are improved, the overall density of the concrete can be reduced, the self weight of the concrete is reduced, the environmental protection property and the sustainable development property of the concrete are improved, and meanwhile, the camphor is added into the concrete, so that damage caused by freezing and melting of water in the concrete can be reduced; the anti-freezing performance of the concrete is improved, and the flowability and operability of the concrete can be improved.
本发明提供一种低收缩高弹性模量的超高性能混凝土及其制备方法，属于混凝土制备技术领域；包括：水泥、骨料、水、化学添加剂、矿物掺合料、植物纤维、樟脑。本发明通过在混凝土中添加植物纤维，提高混凝土的抗拉强度和抗裂性能，并可以降低混凝土的整体密度，减少自重，提升混凝土的环保性和可持续发展性，同时在混凝土中添加樟脑，能够减少水分在混凝土内部的冻结和融化造成的损伤，提高混凝土的抗冻性能，且能够提高混凝土的流动性和可操作性。
