Preparation method of high-ductility and high-strength concrete
The invention discloses a preparation method of high-ductility and high-strength concrete, and belongs to the technical field of concrete processing. The preparation method comprises the following steps: S1, stirring prefabricated raw materials; S2, preparing a concrete initial material; S3, standing; S4, flocculating; and S5, filling a die. The high-ductility and high-strength concrete prepared by the preparation method has the characteristics of light weight, high strength and good weather resistance, can meet the requirements of the construction industry on concrete performance indexes, and has a relatively good application prospect, meanwhile, cement, fine sand and diatomite are compounded as aggregate, so that the internal porosity of the concrete is improved, the elasticity of the concrete is remarkably reduced, the stacking density and the mass density of the concrete are reduced, and the concrete has the characteristic of light weight, by adding the reinforced fibers and the graphene oxide, the crack resistance and the strength of the concrete can be remarkably improved, and polymeric aluminum chloride can improve the strength of the concrete.
本发明公开了一种高延展性高强度混凝土的制备方法，属于混凝土加工技术领域，包括以下步骤：S1、预制原材料的搅拌；S2、混凝土初始料的制备；S3、静置；S4、絮凝；S5、装模，其中，通过本发明的一种高延展性高强度混凝土的制备方法制备得到的高延展性高强度的混凝土具有重量轻、强度高、耐候性好的特点，能够满足建筑业对混凝土性能指标要求，具有较好的应用前景，同时，本发明采用水泥、细砂和硅藻土复合作为骨料，提高混凝土的内部孔隙率，显著降低混凝土的弹性，同时降低混凝土的堆积密度和质量密度，具有轻质化的特点，通过加入增强纤维和氧化石墨烯，能够显著提高混凝土的抗裂性能和强度，聚合氯化铝能够提高混凝土的强度。
