Abstract

Whenever a new material is replaced in concrete, some other tests other than strength and durability need to be carried out to validate the viability of the material replaced. This study aims to investigate the sustaining capacity of the light weight concrete manufactured with compost and Ground Granulated Blast Furnace Slag (GGBS) for M sand and cement respectively subjected to high temperature. Four concrete samples are tested, which includes the control specimen and three specimens are opted based on the optimum mix arrived from the strength and durability studies. Thermogravimetric Analysis (TGA) is done on the samples and they are heated up to 1,000 °C. For the specimens tested, the loss in mass with respect to the temperature is obtained. It is noted that the mass loss of the concrete samples with 15% GGBS along with compost at 0 & 10% is found lower than the control specimen. Also, from the loss in mass, the loss of chemically bound water and free CH content can be found, which aids in contributing strength to the concrete. For the concrete to be sustainable, compost can be replaced at 10% and GGBS at 15%.

利用堆肥和磨细高炉矿渣 (GGBS) 制备轻质混凝土的实验分析：通过 TGA 透视高温特性

每当在混凝土中更换新材料时，除了强度和耐久性之外，还需要进行一些其他测试，以验证所更换材料的可行性。本研究旨在调查用堆肥和磨细高炉矿渣（GGBS）分别替代中砂和水泥生产的轻质混凝土在高温下的承受能力。测试了四个混凝土样品，其中包括对照试样和根据强度和耐久性研究得出的最佳混合物选择的三个试样。对试样进行了热重分析（TGA），并将其加热至 1,000 °C。对于测试过的试样，可获得随温度变化的质量损失。结果表明，添加 15% GGBS 和堆肥（0% 和 10%）的混凝土试样的质量损失低于对照试样。此外，从质量损失中还可以发现化学结合水和游离 CH 含量的损失，这有助于提高混凝土的强度。为了使混凝土具有可持续性，堆肥和 GGBS 的替代比例分别为 10%和 15%。
