Question:

Concrete mix design of cementing material 28d mortar compressive strength of mineral powder fly ash in addition to 10% can also be how much can use other content

If I want to design matching with Gong Ding wins scratching the amount of calcium water sail scared to fly ash 15% mined powder 10% is not done gluing material 28d mortar compressive strength test powder 10% fly ash The amount of 15% (that is, mineral powder 45g fly ash 67.5g cement 337.5g) more

Answer:

You can refer to the mix design rules, there are specific instructions
There is no limit on the total amount of admixture in the design procedure, and you can refer to the durability design procedure or other procedures. Generally, the total amount of gelling material is required (for example, not less than 300), the amount of cement required (for example, not less than 280 for winter, not less than 260 for waterproof concrete). The total amount of admixture is generally between 30% and 50% fluctuations, less uneconomical, more strength growth slow. Most of the projects require less than 50% of the fly ash content (ie, up to 25% + 2%). When you design the ratio, you should be directly based on the strength of the concrete Determine the final match. Do not have to glue the material 28d sand strength test.
The general concrete admixture may not be a large Gong Ding wins scratching the amount of calcium sail scared to the total amount of 35% of the total amount of glue to find the amount of gel, you can mix any fly ash, slag powder ratio but the total Not more than 35% on the line.
