  • Concrete strength Understanding Cement

    Concrete strength. Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. First, though a couple of definitions may be useful: The processes of 'setting' and 'hardening' are often confused: Setting is the stiffening of the concrete after it has been placed. A concrete can be 'set' in that it is no longer fluid, but it may

    201188&ensp·&enspRe: Impact of free lime on grinding efficiency. Hello Pankajbits, All other factors being equal, low free lime clinker (hard burned) is generally harder to grind than clinker with higher free lime. This is due to physical changes in clinker mineralogy and porosity caused by overburning rather than the presence of the free lime itself.
