The solutions to the increasing problem in the energy demand of the world has been expected from the building sector with consumption of high amount of energy. Producing environmentally friendly and energy efficient blended cements and using materials with high thermal performance in terms of insulation and thermal energy storage in buildings are some of these solutions. Calcined marl at optimum temperature is an alternative pozzolan for blended cement productions. The main purpose of this study is to determine of how the thermal performance and mechanical properties of mortar/concrete will be affected by using calcined marl as alternative pozzolan. For this purpose, the mortars/concretes containing calcined marl blended cements were produced. The calcined marl replacement ratios of blended cements were 0, 10, 30 and 50 wt.%. In the study, the strengths and thermal performances of mortars/concretes containing calcined marl blended cements were determined. The test results were compared among themselves and with each other. According to the test results, it was concluded that thermal performances of the mortars/concretes containing calcined marl blended cements could be improved up to 50% replacement ratio without compromising the strength of considered materials.

含有煅烧泥灰岩作为替代火山灰的砂浆/混凝土的热性能

世界能源需求日益增加的问题的解决方案已被期望从消耗大量能源的建筑部门中得到解决。生产环保节能的混合水泥，并在建筑物中使用具有高热性能的隔热和热能储存材料是其中一些解决方案。在最佳温度下煅烧的泥灰岩是混合水泥生产的替代火山灰。本研究的主要目的是确定使用煅烧泥灰岩作为替代火山灰对砂浆/混凝土的热性能和机械性能有何影响。为此，生产了含有煅烧泥灰混合水泥的砂浆/混凝土。混合水泥的煅烧泥灰替代率为 0、10、30 和 50 wt.%。在研究中，测定了含有煅烧泥灰混合水泥的砂浆/混凝土的强度和热性能。测试结果相互比较。根据测试结果，得出的结论是，含有煅烧泥灰混合水泥的砂浆/混凝土的热性能可以提高高达 50% 的替代率，而不会影响所考虑材料的强度。
