[0051]
[0052] Method for preparing super - durable materials, including:
[0053] According to the percentage of quality, we will weigh the following raw materials: 49% grinding cement, 35% level with fine sand, 15% super gray, and solid content account for 1% of the total amount of raw materials; After mixing sand, ultrafine gray and uniform mixture are mixed with water and stir, resulting in a mortar;
[0054] Among them, the grinding cement uses a pure clinical PO524 cement to obtain abrasive treatment, and the specific surface area of the grinding cement is 680m. 2 / kg, fineness of 80 μm screen 6%;
[0055] The graded fragrant sand is mixed after mixing with a half-mixed semi-mixed semi-mixing, and then press the thickness of the fine 1: 1: 1, the crush value is 5%, the fineness is 0.1 ~ 0.6mm, the apparent density More than 2700kg / m 3 , Bulk density is greater than 1400kg / m 3 The mud contains less than 0.1%;
[0056] Ultrafine gray is mixed by the proportion of sili...
Example Embodiment
[0073]
[0074] A method of preparing a super-durable material, the process is basically the same as in Example 1, and the difference is that according to the percentage of mass, weigh the following raw materials: 49% grinding cement, 27% level with fine sand, 8% steel Fibers, 15% ultrafine gray, and solid content account for 1% of the total amount of raw materials.
[0075] The test block is compressed by semi-drying, and the test block 3 days intensity pressure> 850MPa, the anti-frozen level exceeds D200, the anti-seepage level is greater than P12, the ablation level is greater than KS150, chloride ion migration coefficient level (RCM) Method) RCM-V, Electrical flux q-V, anti - carbon transformation level T-V.
