所谓高强度混凝上一般是指抗压强度不低于50Mpa的混凝土。可用于高层建筑,桥梁预应力混凝土桩、大型混凝土重力式近海结构等。高强度混凝土具有自重轻、节约材料、成本低等优点。制备高强混凝土的方法主要有:1、使用高效减水剂;2、掺用粉煤灰、硅粉等矿物质细料;3、采用高温蒸养法;4、采用加压成型法;5、用聚合物浸渍混凝土;6、用聚合 The so-called high-intensity coagulation generally refers to concrete with a compressive strength of not less than 50 MPa. It can be used in high-rise buildings, bridge prestressed concrete piles, large concrete gravity-type offshore structures, etc. High-strength concrete has the advantages of light weight, material saving, and low cost. Preparation of high-strength concrete methods are: 1, the use of superplasticizer; 2, mixed with fly ash, silica fume and other mineral fines; 3, the use of high-temperature steaming method; 4, the use of pressure forming method; 5, Concrete impregnation with concrete; 6, with polymerization
