Large-particle-size aggregate concrete as well as preparation method and application thereof
The invention belongs to the technical field of building materials, and particularly discloses large-particle-size aggregate concrete as well as a preparation method and application thereof. The preparation raw materials of the large-particle-size aggregate concrete comprise a gel material, coarse aggregate, fine aggregate, an additive and water, the coarse aggregate meets the condition that the number of groups with the passing rate deviation value larger than +/-5% in sieve pores does not exceed two, and the passing rate deviation value is the difference value between the passing rate of the sieve pores with the nominal diameter being D and the synthetic grading passing rate. The invention also provides a preparation method of the large-particle-size aggregate concrete and application of the large-particle-size aggregate concrete in preparation of building materials. The large-particle-size aggregate concrete has the advantages of being good in working performance, high in strength and resistant to cracking, additional high-cost additives are not needed, and construction operation steps are conventional, simple and convenient.
本发明属于建筑材料技术领域，具体公开了一种大粒径骨料混凝土及其制备方法与应用。本发明的大粒径骨料混凝土的制备原料包括凝胶材料、粗骨料、细集料、外加剂和水，其中粗骨料满足在筛孔中的通过率偏差值大于±5％的组数不超过两组，所述通过率偏差值为公称直径为D的筛孔通过率和合成级配通过率之间的差值。本发明还提供该大粒径骨料混凝土的制备方法和在制备建筑材料中的应用。本发明的的大粒径骨料混凝土具有工作性能好、强度高和抗开裂的特点，且无需额外的高成本添加剂，施工操作的步骤常规简便。
