E. Cement

The raw materials like: limestone, chalk, shale, clay etc., mixed with water, are crushed, ground and blended. They are now submitted to a chemical process in a rotary kiln until they combine into clinker. From the clinker opportunely mixed with gypsum, the cement factories obtain the modern Portland cement, that may be modified in more and more sophisticated binders like expansive mortars, pre-mixed cements etc.
In section “Cement & Mortars” Macben proposes a complete range of equipment for : fineness, consistency, setting-time, workability, soundness, flow, fly ash, lime reactivity and slaking, chemical test, etc.; and for mixing, moulding, curing and strength tests, to satisfy all the above quality variables, in compliance with the EN, ASTM and the most known International Standards.
