铝粉对EPS节能保温墙板性能的影响

摘要

EPS节能保温墙板是一种轻型且保温效果好的保温材料，若在制作过程中加入铝粉，铝粉参与水化产生的氢氧化钙反应，生成氢气泡，使混凝土内部形成许多蜂窝状的结构，能增强保温效果。但当掺入过量铝粉时，发气量过大，墙体内部孔隙率过大，将影响混凝土的抗压强度，为此需要对铝粉的掺量进行研究。%EPS insulation energy-saving wall panels is a kind of light and heat preservation materials with good effect, if adding aluminum powder in the production process, Aluminum can react with the hydration of calcium hydroxide and generate hydrogen bubble, and form a number of cellular structure Inside the concrete, which enhances the heat preservation effect. When mixed with excess aluminum powder, it will have too much gas, and the large porosity impacts the compressive strength of concrete. So to study the content of aluminum powder is needed.
