10,不发火细石混凝土骨料一般为石灰石、白云石.粒径宜为0.15~5m

10. Non-flammable fine stone concrete aggregates are generally limestone and dolomite. The particle size should be 0.15~5mm, the mud content should not be more than 3%, and the organic content should not be more than 0.5%. The cement uses ordinary Portland cement. The strength grade is not less than 42.5, and the moldings of the surface layer division should be made of non-pyrophoric materials, and check at any time when configuring. Non-flammable ground can only be used after passing the non-flammable test.

10, non-fire fine stone concrete bone is generally limestone, dolomite. Particle size should be 0.15 to 5mm, mud content should not be greater than 3%, organic content should not be greater than 0.5%, cement using ordinary silicate cement, its strength level is not less than 42.5 levels, the surface layer of the insert should be used without fire material, configuration at any time to check. The ground without anger must be qualified by the non-fire test before it can be used.

10. The aggregate of non igniting fine aggregate concrete is generally limestone and dolomite. The particle size should be 0.15 ~ 5mm, the mud content should not be more than 3%, and the organic matter content should not be greater than 0.5%. The ordinary portland cement should be used as the cement, and its strength grade should not be less than 42.5. The non combustible material should be used for the inlay of the surface layer division, which should be checked at any time during configuration. The non fire ground can be used only after passing the non ignition test.<br>
