摘要
高强混凝土仅是一个相对的概念 ,只要选用的水泥有足够的强度 ,完全可以用普通材料和常规工艺生产出优质的高强混凝土。高强混凝土由于对水泥强度及水灰比的波动更为敏感 ,生产中应加强控制 ,除严格按配比配料外 ,特别应注意混凝土坍落度的波动。
The so called high strength concrete is only a general relative term or concept.Only adopting the quality cement with sufficient strength,the high strength concrete can be readily produced just with ordinary materials and technology.Because the high strength concrete is very sensitive and highly affected by cement strength and fluctuation of water-cement ratio,it is ,therefore,that during its production a strict control of material's mixdesign and fluctuation of slump of concrete should be carefully carried out.
