Constructii %D 2011 %I NR&DI URBAN-INCERC %X The making of complex researches of resistance and compactproperties of concrete on the base of limestone offal that contains a huge pitch of concrete components on the base of nominal materials. They studied three types of concrete based on residue from crushing limestone: concrete on small particles as filler in concrete were used to crushing limestone residues career Mic uti; carbonate concrete, the coarse-grained aggregate as they used limestone gravel career low, and as small aggregate - residues from crushing limestone in the same career; cheramzit concrete on gravel and waste from crushing limestone. These studies reveal general rules of these properties of concrete according to their characteristic structure. %K strength and compaction properties %K concrete cheramzit %K small particles %U http://uac.incd.ro/Art/v2n3a5.pdf
