Slag-alkali lightweight concrete with corn waste aggregate

Abstract

The paper presents a technical solution for obtaining effective slag-alkali lightweight concrete on the basis of corn waste. The granulometric compositions, types and forms of waste at grinding for obtaining slag-alkali lightweight concrete on the basis of corn waste are developed; compositions and formulations of slag-alkali lightweight concrete based on shredded corn waste have been developed. As a result of the development of a new scheme of changing the mechanism of strength formation of slag-alkali lightweight concrete and optimization of its composition, lightweight concrete composites with compressive strength of 2.9-4.5 MPa and bond strength of aggregate with mineral matrix of 45.7-59.7 MPa were obtained.
