Szukana fraza: [Abstract = "The mechanical test results show that compressive strength and mechanical behavior of an ecological cement mortar made with marble waste as natural sand improved significantly. However, marble\-based mortars with 100% of marble sand have given a mechanical strength similar to that obtained by control cement mortar \(100% natural sand\). It was also noted that it an ecological cement mortar made with 30% of marble powder as an addition a supplementary material can be obtained. This leads to a reduction in cement consumption and a reduction in CO2 gas emissions caused by cement production."]
