Abstract

Cement in concrete، which is the most important part of this material and causes the concrete mixture to form by creating adhesion between the aggregates. Due to the qualitative and quantitative improvement of cement in concrete mix، as well as the reduction of environmental pollution and the improvement of energy consumption in the cement and concrete industry، researchers and researchers are looking for solutions to achieve These goals with an attitude to sustainable development. The use of cement supplements and pozzolanic materials has been one of these solutions. The reason for the widespread application of these materials، apart from environmental protection and economic cost reduction، is to improve concrete's mechanical properties and durability in destructive environmental conditions. In this study، ordinary and heated zeolite was used under three different temperatures as pozzolan. Initially، concrete samples were made with 16 mixed designs to study compressive strength and Islamp samples. In the next step، the design of optimal mixtures to measure concrete resistance in unhealthy environments was investigated and investigated. The addition of heated zeolite under 200 degrees compared to conventional zeolite in concrete has increased resistance، especially in the long run، compared to reference samples. Also، the zeolite heated under 200 degrees at a young age and higher strength results in better resistance. The results of durability tests in the second phase showed that the durability of higher-strength samples due to more zeolite substituted 200-degree zeolite cement in the sulfate environment was more resistant than conventional concrete.
