Effect of curing methods and scrap tyre addition on properties of mortars

Abstract

Mechanical, thermal conductivity, and porosity properties of scrap tyre incorporated mortars are examined experimentally in this study for various curing conditions. Cement mortars were prepared by adding 0%, 1%, 5%, 10% and 18% of scrap tyre by cement weight, and the mortars were subjected to three curing procedures for 14 weeks. The lowest thermal conductivity values were obtained on samples containing 18% of scrap tyre by water curing and wetting-drying curing as 1.09 and 1.14 W/mK, respectively. The maximum compressive strength of 61.5 MPa was obtained on a pure sample cured by wetting and drying, while the flexural strength of pure and a 1% additive incorporated samples, which were also cured by wetting-drying, amounted to 9.1 and 8.2 MPa, respectively.
