EPS混凝土性能的影响因素研究

Study on Influencing Factors of Performance Improvement of EPS Concrete

EPS混凝土作为一种新型的保温材料,应用越来越广泛,但存在强度较低,容易离析、泌水等缺点。为了提升EPS混凝土的力学性能与工作性能,文中通过提高水泥用量,单掺和复掺硅灰、粉煤灰、矿粉,添加纤维素醚等方式,对EPS混凝土的力学性能及工作性能进行了研究。结果表明,提高水泥用量、外掺硅灰、粉煤灰、矿渣能明显提升EPS混凝土强度;纤维素醚、硅灰能明显改善EPS混凝土的工作性能。

As a new type of thermal insulation material,EPS concrete is used more and more widely,but it has some disadvantages such as low strength,easy segregation and bleeding,in this paper,the mechanical properties and workability of EPS concrete are studied by increasing cement content,adding silica fume,fly ash,mineral powder and adding cellulose ether The results show that the strength of EPS concrete can be obviously increased by increasing the amount of cement,adding silica fume,fly ash and slag,and the workability of EPS concrete can be obviously improved by adding cellulose ether and silica fume.
