Studies on the Mechanical Properties and Chemical Reactivity of Hydrophobized Lightweight Aggregate Concrete with the Incorporation of Sewage Sludge

Abstract

Weakened by sewage sludge, the lightweight aggregate-concrete in this article is a combination of sludge from
municipal sewage treatment plants and lightweight aggregates. Laboratory tests of material physical properties are
discussed in this article. Admixing reactive polysiloxanes water emulsion with a substance that absorbs water reduced its
water absorption capacity. An indirect approach for detecting moisture in porous materials was used: Time Domain
Reflectometry. Both types of lightweight aggregate-concrete had their heat conductivity coefficients measured. Light
aggregates reinforced with sewage sludge were found to be suitable for the creation of future products after an analysis of
their moisture and heat qualities.
