【 摘 要 】

This paper is concerned with investigation of waste products of boron and metakaolin utilizes in cement mortar. Application of waste products leads to minimization of gross cement amount in mortar production which helps to decrease CO2 emissions caused by manufacture of cement and recycle byproduct waste materials. Along with supplementary materials, application of 1% Polydos TS14 solution was investigated. Physical properties such as compressive and flexural strength at age of 2,7 and 28 days were determined and compared with reference mixture. The results showed that cement replacement materials had affected mechanical properties, although addition of TS14 partially amortized those negative effects. The use of colemanite at the concentration over 7 wt.% showed unacceptably low compressive and flexural strength performances. Also, replacement of Portland cement by 30 wt.% metakaolin showed poor strength. The mixes with TS14 solution showed notable enhancement of compressive and flexural strength. The most adequate proportions for each of supplementary materials have been designed.
