The variety of approaches to tackle climate change reflects the size of this global problem. No technology will act as a panacea to cure the greenhouse gas emissions problem, but new building materials with byproducts or even wastes have the potential to play a major role in reducing the environmental impacts of the building sector. In this study, three potential solutions of concrete with dispersed reinforcement in the form of recycled fibers (polypropylene, glass and steel) were examined. The aim is to present a detailed analysis of the thermal properties of new building materials in an experimental approach. Concrete mixtures were prepared according to a new, laboratory-calculated recipe containing granite aggregate, a polycarboxylate-based deflocculant, Portland cement (52.5 MPa) and fibers. This experimental work involved three different contents of each fiber (0.5%, 0.75% and 1.0 wt.%), and all tests were carried after the complete curing cycle of concrete (28 days).
应对气候变化的方法多种多样，这反映出了这个全球性问题的规模。没有哪种技术能成为解决温室气体排放问题的万灵药，但含有副产品甚至废弃物的新型建筑材料有潜力在减少建筑行业对环境的影响方面发挥重要作用。在本研究中，对三种以再生纤维（聚丙烯、玻璃和钢）形式分散增强的混凝土潜在解决方案进行了研究。目的是以实验方法对新型建筑材料的热性能进行详细分析。混凝土混合物是根据一种新的实验室计算配方制备的，该配方包含花岗岩骨料、聚羧酸盐基解絮凝剂、波特兰水泥（52.5兆帕）和纤维。这项实验工作涉及每种纤维的三种不同含量（0.5%、0.75%和1.0重量%），并且所有测试都是在混凝土完全养护周期（28天）后进行的。
