STEEL FIBER REINFORCED CONCRETE Nguyen Van CHANH (1) SUMMARY , The concrete alone, typically, should have a slump of 50-75 mm greater than the desired slump of the SFRC Of course, the fibres should be added free of clumps, usually by first passing them through an appropriate screen Once the fibres are all in the mixer, about 30-40
Researchers from Delft Technical University in the Netherlands have developed concrete that can heal itself using special bacteria Concrete is the most widely used building material in the world but is prone to cracks which means that it needs to be reinforced with steel and in some cases fixed or replaced when cracks expand too much
What kind of concrete to use for a dog kennel Being in the concrete business, I've poured many concrete slabs for dog kennels Whether you have one dog or more, you know they dig their way through just about anything But a dog isn't going to cause damage to concrete if it's the right mix design Concrete can be made a lot of different ways .
