\u00cen\u021belegerea Bazelor: Ce Face Betonul S\u0103 Func\u021bioneze<\/h2>\r\n
\r\n

Betonul combin\u0103 ciment, ap\u0103 \u0219i agregate precum nisip sau pietri\u0219.

Plasticizatorii, numi\u021bi \u0219i reduc\u0103tori de ap\u0103 conven\u021bionali, sunt agen\u021bi chimici care sporesc manevrabilitatea betonului \u00een timp ce reduc cantitatea de ap\u0103 necesar\u0103 pentru a atinge o anumit\u0103 consisten\u021b\u0103.
