Abstract
Inventia se refera la materialele de constructie si este utilizata pentru prepararea betonului usor de inalta rezistenta. Esenta inventiei consta in aceea ca compozitia contine un amestec de ingrediente, in % mas. :ciment Portland 15...20nisip 14...20silice fin macinata 3...15pietris cu fractia 5...15 mm 20...40superplastifiant pe baza de policarboxilati eterici 1...3apa restul,si umplutura usoara de forma sferica cu dimensiunea de 5...15 mm in cantitate de 13...41% de la volumul amestecului. Totodata, in calitate de umplutura pot fi utilizati polimeri expandati, bile cave de polimeri sau de sticla. Rezultatul consta in imbunatatirea proprietatilor de baza ale betonului si anume a densitatii in intervalul 1000...2445 kg/m3 si a rezistentei la compresiune in intervalul 12...85 MPa, imbinand astfel proprietatile betoanelor grele (rezistenta inalta) cu ale betoanelor usoare (schimb de caldura mic). ŕ
