Abstract
Invenţia se referă la materialele de construcţie şi este utilizată pentru prepararea betonului uşor de înaltă rezistenţă.Esenţa invenţiei constă în aceea că compoziţia conţine un amestec de ingrediente, în % mas. :şi umplutură uşoară de formă sferică cu dimensiunea de 5...15 mm în cantitate de 13...41% de la volumul amestecului. Totodată, în calitate de umplutură pot fi utilizaţi polimeri expandaţi, bile cave de polimeri sau de sticlă.Rezultatul constă în îmbunătăţirea proprietăţilor de bază ale betonului şi anume a densităţii în intervalul 1000...2445 kg/m3 şi a rezistenţei la compresiune în intervalul 12...85 MPa, îmbinând astfel proprietăţile betoanelor grele (rezistenţă înaltă) cu ale betoanelor uşoare (schimb de căldură mic).
