摘要：
This paper describes the possibility of using fine concrete recycled material to produce lightweight blocks. We focus on mechanical properties of foamed cement matrix. The samples contain 1: 1 cement and finely ground waste concrete. The matrix was lightened with various foam agents and subsequently compressive strength and thermal conductivity were measured. The results obtained from these samples were compared with reference samples.
